We have been listening/reading about the accident in Mayapuri, Delhi in which at least two labourers have lost life because of radiation exposure. A few days back it was told that the radiation source was Cobalt 60, which found its way to the scrap dealer's shop. Initially, it was surmised that the scrap might have been imported, but yesterday it was reported that its source was University of Delhi's Department of Chemistry,

I was indeed intrigued, because i know no one in the deptt who does research in Radiation Chemistry. So, i did a bit of Net research. Within a few minutes, i could guess the name of The Faculty member! It is Professor B. K. Sharma, who was a faculty member in Chem Department, some forty years ago, when i had joined as an undergraduate student. I could trace out a research paper published in 1985 with a coworker from Bareilly.

So, how did the radiation source find its way to the scrap market? Obviously Professor Sharma must have retired long ago (possibly he might have passed away too!). So the equipment he procured at that time, must have been lying discarde in some attic of the department all these years. Off late, there has been a drive to clean up to vacate some useful working space in the University. The protocol for that, i have come to know recently, is to appoint a committee of Faculty members to review the nature of the items to be disposed off and the manner to be used. In the present case, i won't be very surprised if no committee member cared to look through the stock register carefully, or if they did cared to find out the likely environmental threat, if an equipment like a Gamma Irradiator (which has Cobalt 60 in it) found its way to the scrap market, because not every chemistry faculty member can be expected to know about each such equipment. So, the procedure must have been followed in a routine manner.

Now that a serious accident has happened, what corrective steps the University authorities can take?

I have a few suggestions:

1. The potential risks for all research equipment being procured by the University must be documented at the time of its procurement, so that whenever it needs to be disposed off, the people involved can at least be aware of them.

2. Whenever a faculty member retires, he must be required to submit a report about each and every equipment procured by him for his laboratory, with a word of caution!!

Cool

From the news reports published today in newspapers it appears that it is not an isolated incident Smile Many science departments have been adopting a callous approach towards discarding nuclear waste. That calls for serius concern. All faculty members conducting any research activity using hazardous material should be required to give an undertaking that they would take all care for the disposal of waste, whether it we radioactive material or environmentally hazardous chemical substances. If the University does not initiate such steps it would become totally socially irresponsible Sad

The University must learn a lesson from this tragic incident, if it wants its name in annals to go down as a socially responsible university.

Faculty members of various science departments choose the subject of their research activity, based on the fashion of the day; that gives them more opportunities for career advancement through frequent jaunts to western countries. It would be rare if any of them would be concerned about the environmental impact of their research activity. I remember that during by Ph.D. research work at IITK i used to dump into the drain many liters of methanol/chloroform almost daily for many months. I never cared for the impact of these toxic chemicals whether on the environment or my health. Similarly I have lately witnessed how we trash a number of computers that may not be very old, and hence still usable, only because we can get grants for purchasing brand new models. An activity that generates a lots of e-waste, about which no one is concerned a bit. Can't these computers be recycled? Can't some people from the academic community think of some innovative ideas that would minimize such waste?

Definitely there is a need to give some serious thought on these issues within the science community of the University Smile

Off late the media is live with the comments of a faculty member in the Chemistry department. This gentlemen had a dubious record. So far, i can recollect he was appointed because of his closeness to a OBC cabinet minister. Later he even succeeded in getting a plum position of the VC of a university in UP. His comments are at best political in nature!

Our present VC can hardly be held responsible for this incident! At best he might be responsible for the undue haste in initiating the write-off procedure. But then we must remember that he had to ensure working space for several faculty members that had to be added to the department because of the recent OBC reservation directive of the Central Government. He could do little else then to get some space vacated that has been lying waste within the department. The faculty members who were the members of the write-off committee are the real culprits. They did not carry out the responsibility entrusted to them in a responsible manner Sad

Today, after reading the newspaper, i need to correct myself, Dr. Sharma is very much alive, I wish him a longer happy life:

Prof who used gamma irradiator says DU wrong in selling it

New Delhi: Professor B K Sharma,who had last used the gamma irradiator in Delhi University 25 years back,said the chemistry department should not have disposed of the instrument in the first place.Speaking to Times City on Friday,82-year-old B K Sharma said, I had received the gamma irradiator through UGC for my research on gamma rays.It was a very safe instrument and there was no question of disposing it of.
DU had bought the gamma irradiator for his research titled Effect of Gamma Rays on Compressed Cyanide in 1968 for around $20,000.Though B K Sharma,who retired in 1985 and is now bedridden,could not remember the cost of the equipment,he said he had five to six students doing their PhD research work on this instrument at one time under him. I worked on it for 20 years and never faced any problem.It was a very safe instrument.The cobalt-60 was inside a heavy lead cover as it did not let radiation come out of it.The crisis happened only because the scrap dealers dismantled the instrument, B K Sharma said in his shaky voice.
B K Sharma who now lives in Ashok Vihar,said, I dont understand why the university sold it to scrap dealers.Now,lets see how they handle the situation.I cant comment on how and why they did it. Those guided by B K Sharma in their PhD research recall the fascination for this instrument as it was a rare possession at that time.Though it had been lying unused for more than two decades,its entry in DU was dramatic. The instrument didn't have a normal installation.I had heard it arrived on the highest building on the campus in a helicopter in 1968.It was the only machine,which was about six feet,to be kept in an 8X10 feet room, said Dr D S Sharma,who completed his PhD on Effect of Radiation on Amino Acids and Peptides under professor B K Sharma in 1979 and now teaches chemistry in DUs Zakir Husain College.
According to D S Sharma,the machine might have had two to five kilogramme of Cobalt-60 in it.In case of any negligence in handling,the machine would switch off on its own, he added.Babha Atomic Research Centre constantly monitored the use of gamma irradiator back then, he said. We used to spend just a few seconds inside the lab with the machine and always noted the timing. BARC used to give us badges which we wore on the chest.It recorded the amount of radiation we were exposed to.We used to sent those badges back to BARC so that it could check the level of exposure, Dr D S Sharma said.
He added, They could then ask those to stop doing the experiments with the machine if their exposure level was found to be more than the permissible level.BARC even provided us with special jackets to wear while inside the room.If the number of Cobalt-60 bars had to be reduced or increased,BARC experts had to be called in.
He said that the machine should not have been sold off that too for a lakh of rupees as it was in a working condition.
According to Dr Sharma,its impossible that the department of chemistry was unaware of Cobalt-60 or could miscalculate its radioactivity period. If the head of department could not even figure that out and auctioned it to scrap dealers,he is not fit to be a scientist,not even a lab assistant, Dr Sharma said.

B K Sharma (left) and D S Sharma in 1981


I also came to know the names of the faculty members, who were the members of the write-off committee, and hence the persons who should be held responsible, because they did not do their duties properly. These include Prof. R. C. Rastogi, a computational chemist, about two years senior to myself, Professor. N. K. Kaushik, an inorganic chemist, who joined the Chemistry epartment while I was an undergraduate student, and the Head of the Department, Professor V. S. Parmar and Prof. Rup Lal a zoologist.

...........according to faculty members of the chemistry department,the head of the department,V S Parmar;two other faculty members,N K Kaushik and R C Rastogi;and dean of sciences,Professor Roop Lal,were responsible for the auction.

One cannot expect any responsible behavior from Prof. Rastogi, and Prof. Kaushik, they are on the verge of retirement and hence took this unlucrative and unattractive responsibility only it did not appear to be very demanding. I have known Rastogi ever since he was a postgraduate student, he used to study in the Hans Raj College library till late in night, while i was also there. The department preferred him over me, when he was appointed in the Chem Department in 1987, mainly because he was a student of the Head of the Department, But then that is hardly an aberration, that has been rampant in Indian society, because people are appointed in responsible positions primarily due to the compulsions faced by the selection committee. The case gets public only after it is found how irresponsible they are, say the case of the officer who was a spy pin the Indian High Commission in Pakistan, or the Cabinet Minister for Telecom, who gave away the 2G spectrum for a song!!!

A clear cut case of Privileges vs Responsibilities; we all want to enjoy the privileges that a powerful post provides, but are often found shirking from the social responsibilities that are expected from us in return!!

In my opinion the members of the write-off committee responsible for this very irresponsible write off must be penalised in an exemplary fashion, so that members of such committees in future do not discharge their duties in such an irresponsible manner, In the present case they were all senior faculty members nearing their retirement, so they discharged their responsibility in a very casual manner leading to lot of suffrage to several persons. But the tragedy can be much more serious, as several Co-60 pencils are still reported to be missing; just imagine the consequences if they fall in the hand of some kind of terrorists Evil or Very Mad

That appears to be quite reasonable. The same sentiment has been echoed in the editorial of TOI today:
Times of India wrote:

Criminally Careless
Delhi Universitys role in radiation death reveals the lack of safeguards in our system
If the radiation leak incident in the national capital had not tragically claimed a life and left seven others in critical condition,it would seem almost farcical.That Delhi Universitys chemistry department would auction off an irradiator knowing full well that it contained cobalt-60,a highly radioactive substance,beggars belief.And that it would then keep mum while people landed up in hospital because of radiation poisoning it would be a stretch to argue that they had no inkling of the truth of the situation given that the scrap dealer connection was reported early is a damning indictment of its criminal negligence and irresponsibility.But beyond the specifics of this case,several questions about safety protocols and enforcement measures in dealing with such material in the country at large have been raised.
Radioactive material in nuclear power institutions,whether civilian or military,is presumably under stricter safeguards.But that still leaves a whole host of institutions with access to it scattered across the country,primarily educational and research organisations,and hospitals.Neither is there a comprehensive list of such organisations and the material in their possession with regulatory bodies like the Atomic Energy Regulatory Board.Why it has taken the government so long and loss of life to wake up to the obvious dangers posed by unregulated handling of hazardous material is a question worth asking.
Even now,the reaction by Delhi University officials betrays a fundamentally flawed way of looking at the issue.According to its vice chancellor Deepak Pental,the mistake made by the chemistry department personnel was in miscalculating the cobalt-60 s radioactive time and not realising that it might still be active.He misses the point entirely.Whether still active or entirely inert,the mistake lies in disposing of radioactive material in such cavalier fashion instead of handing it over to institutions like the Bhabha Atomic Research Centre.Neither does the establishment of a three-member committee by the varsity to investigate the incident inspire much confidence.Any such process must be carried out by an external watchdog body.
Charges have been made about more radioactive material missing and buried on the university grounds.These must be looked into along with the auctioning of the irradiator and culpability decided. Given that the callousness of university personnel has cost a life and placed others in danger,strict punitive measures under the law are called for. And as importantly,the lessons drawn from this must be put to use to ensure that there are no repeats

Here's yet another interesting news report about the incident published in THE HINDU newspaper:
R. Ramachandran wrote:

A former storekeeper of the Chemistry Department of Delhi University successfully prevented the disposal of the gamma cell irradiator for two years, according to some former senior faculty members and non-teaching technical personnel of the department who, however, do not wish to be named.

Apparently, there have been moves to sell off the gamma irradiator through public auction since 2007-08. But the then storekeeper, who has served the department for long and was aware that it was dangerous do so, seems to have been successful in prevailing upon the faculty members on the departmental ‘write-off' committee not to consider the irradiator for auctioning.

“It is common knowledge in the department, certainly among the senior faculty, that we have a gamma cell irradiator with cobalt-60 source in it,” said the former department professor.

The present keeper, perhaps not being as aware of the properties of the equipment, did not seem to have raised any objection when its auction was once again mooted earlier this year. But what is unbelievable is that, while a lower rung employee rightly managed to stall its disposal, the faculty members who constituted the present write-off committee could not see the obvious dangers of their recommendation to dispose of the gamma irradiator.

What is also curious is that the committee did not consider it necessary to consult the 82-year-old B. K. Sharma, who was the last person to work with the gamma irradiator till 1985, if the current faculty felt that adequate information on the equipment was lacking. “Nobody asked me. I am in Delhi only,” said Dr. Sharma. Speaking to The Hindu, he said it was generally known that the source was a strong one and disposing it of like that was a serious mistake.

“I don't know how this could happen. They are expected to be knowledgeable and they should have known that the source still had high leftover radioactivity after 40 years.”

I really wonder if the knowledge about gamma rays and Cobalt 60 is commonplace for a chemistry teacher/student! I did a bit of search on the Net and found the following information, which may be useful for the student visitors of Vimarsh:]
WIKIPEDIA wrote:

Cobalt-60 (60Co) is a radioactive isotope of cobalt. Due to its short half life of 5.27 years (60Co is not found in nature. It is produced artificially by neutron activation of 59Co. 60Co decays by negative beta decay to the stable isotope nickel-60 ((60Ni). The activated Ni-atom emits two gamma rays with energies of 1.17 and 1.33 MeV..

Main uses for 60Co:

* As a tracer for cobalt in chemical reactions,
* Sterilization of medical equipment,
* Radiation source for medical radiotherapy,
* Radiation source for industrial radiography,
* Radioactive source for leveling devices and thickness gauges,
* As a radioactive source for food irradiation and blood irradiation, and
* As a radioactive source for laboratory use.
.................
The measure of gamma rays' ionizing ability is called the exposure:

* The coulomb per kilogram (C/kg) is the SI unit of ionizing radiation exposure, and is the amount of radiation required to create 1 coulomb of charge of each polarity in 1 kilogram of matter.
* The röntgen (R) is an obsolete traditional unit of exposure, which represented the amount of radiation required to create 1 esu of charge of each polarity in 1 cubic centimeter of dry air. 1 röntgen = 2.58×10−4 C/kg

However, the effect of gamma and other ionizing radiation on living tissue is more closely related to the amount of energy deposited rather than the charge. This is called the absorbed dose:

* The gray (Gy), which has units of (J/kg), is the SI unit of absorbed dose, and is the amount of radiation required to deposit 1 joule of energy in 1 kilogram of any kind of matter.
* The rad is the (obsolete) corresponding traditional unit, equal to 0.01 J deposited per kg. 100 rad = 1 Gy.

The equivalent dose is the measure of the biological effect of radiation on human tissue. For gamma rays it is equal to the absorbed dose.
.............
Shielding from gamma rays requires large amounts of mass. They are better absorbed by materials with high atomic numbers and high density, although neither effect is important compared to the total mass per area in the path of the gamma ray. For this reason, a lead shield is only modestly better (20-30%) as a gamma shield than an equal mass of another shielding material such as aluminium, concrete, or soil; the lead's major advantage is in its compactness.

The higher the energy of the gamma rays, the thicker the shielding required. Materials for shielding gamma rays are typically measured by the thickness required to reduce the intensity of the gamma rays by one half (the half value layer or HVL). For example gamma rays that require 1 cm (0.4") of lead to reduce their intensity by 50% will also have their intensity reduced in half by 4.1 cm of Granite rock, 6 cm (2½") of concrete, or 9 cm (3½") of packed soil. However, the mass of this much concrete or soil is only 20-30% larger than that of this amount of lead. Depleted uranium is used for shielding in portable gamma ray sources, but again the savings in weight over lead is modest, and the main effect is to reduce shielding bulk.
..................

60Co might be an efficient heater for a radioisotope thermoelectric generator. But in contrast to the commonly used 238Pu, its power is nearly exhausted after 10 years. It is also more difficult to absorb γ-ray energy of 60Co than the energy of α-particles emitted by 238Pu.

60Co in a cobalt bomb, a theoretically feasible but extremely "dirty" form of nuclear weapon whereby a tamper of 59Co is irradiated by neutron radiation from the fission process and transmuted to 60Co.

The creation of 60Co is an important step in nucleosynthesis. Without the 60Co step, no elements from number 27 through 83 would be created in supernovas.[3]
............
Gamma radiation
Gamma radiation also known as gamma rays (denoted as γ) is electromagnetic radiation of high frequency (very short wavelength). They are produced by sub-atomic particle interactions such as electron-positron annihilation, neutral pion decay, radioactive decay, fusion, fission or inverse Compton scattering in astrophysical processes. Gamma rays typically have frequencies above 1019 Hz, and therefore have energies above 100 keV and wavelength less than 10 picometers, often smaller than an atom. Gamma radioactive decay photons commonly have energies of a few hundred keV, and are almost always less than 10 MeV in energy.

Because they are a form of ionizing radiation, gamma rays can cause serious damage when absorbed by living tissue and, are therefore a health hazard.All ionizing radiation causes similar damage at a cellular level, but because rays of alpha particles and beta particles are relatively non-penetrating, external exposure to them causes only localized damage, e.g. radiation burns to the skin. Gamma rays and neutrons are more penetrating, causing diffuse damage throughout the body (e.g. radiation sickness, increased incidence of cancer) rather than burns. External radiation exposure should also be distinguished from internal exposure, due to ingested or inhaled radioactive substances, which, depending on the substance's chemical nature, can produce both diffuse and localized internal damage. The most biological damaging forms of gamma radiation occur in the gamma ray window, between 3 and 10 MeV, with higher energy gamma rays being less harmful because the body is relatively transparent to them.

Radiation waste: DU Chemistry dept head retires, probe on

The Chemistry department of Delhi University got a new head after V S Parmar, who had officiated over the auction of Gamma Irradiator to scrap dealers, retired on Saturday.

A K Bakshi, a senior Chemistry professor, took over from Parmar.

According to a source in the university, Parmar's retirement is not connected with the latest controversy surrounding the auction of radioactive waste — he had reportedly applied under the Voluntary Retirement Scheme earlier.

A faculty member said Parmar is slated to join an institution in the US. "He had told me last week that he would leave the country in a weeks' time," the faculty member said. "He could leave any time now — his family is already in the US."

Vice-Chancellor Deepak Pental, though, called Parmar's immediate relocation to the US a "rumour".

Pental refused to discuss the course of action if the three-member inquiry committee formed by the university found Parmar guilty.

Experts and the Delhi Police had, on Wednesday, traced the source of the radioactive material (Cobalt-60) found in West Delhi's Mayapuri scrap market to a laboratory in DU's Chemistry department. One person has died and at least two others are stated to be critical following exposure to radiation at the scrap market.

Meanwhile, documents with Newline show Parmar had proposed the auction of the Gamma Irradiator this January 20. In a letter to Pental, he said the department needed to demolish one block to construct a new block named 'TR Seshadri Block'.

In its only meeting on February 6 this year, a 10-member committee gave permission to dispose "obsolete equipment, apparatus and furniture".

The Pro V-C approved the auction on February 15, and DU's Engineering department notified it the following day. The radioactive nature of one of the "obsolete" equipment is mentioned in none of the communiqués.

A team from the Atomic Energy Regulatory Board inspected a room where the Physics department keeps its radioactive sources. Pits in the room, where a Radium-Beryllium source was kept, was flooded in end-January, though the cause of flooding is not known. "There were minor discrepancies in the pit; there's nothing to fear," AERB's Raju Kumar was quoted by PTI.

Sources said Physics HoD D S Kulshreshtha had been informed on February 1 and 2 about it. A letter was sent to Pental and Kulshreshtha on February 19. The letter also warned of a possible crack in the glass container used to store the radioactive source.

No action was taken.....................

That's indeed very interesting! No HOD would dare to take any step without the prior consent of the VC! and considering that the equipment was lying in the department for more then 25 years, and no HOD cared to proceed to dispose it of, obviously the VC can be expected to know about it, though he may be ill informed about the risks of selling te radiator as scrap. But the as is usually the case no HOD would dare to hold an opinion different from the diktat of the VC Sad

Nevertheless i would expect that senior science teachers holding responsible positions in University departments, would act in a more responsible manner instead of like a sycophant petty clerk, who is only too fearful for the position he holds in the University bureaucracy, as it appears to be the case in the case under discussion here. But, then teachers apparently teach their students only lessons of sycophancy in India, not to hold correct opinions boldly. As reported above, Professor Parmar, had opted to retire, then what were the compulsions for him to take such irresponsible decisions (except perhaps a favorable recommendation for a plum position abroad after he retires) Sad

Today, while leaving the Academic Research Center Building where CSEC and hence my office is located, i noticed a clipping from The Pioneer Newspaper dated 28 May 2010 on the ILLL notice board. It reported that the Vice Chancellor has constituted a committee, which includes Professor Ashok Bakshi, who is at present the HOD of the Chem Deptt to frame the guidelines for conduct of experiments in the DU science labs. Soon all science students would be provided a booklet detailing these guidelines.

In the meantime, there is a relenless atteck on the DO administration for the accident, For example the following Editorial that appeared in THE HINDU a couple of days ago:

Quote:

The Mayapuri metal scrap market tragedy resulting from the callous disposal of equipment containing radioactive source cobalt-60 as scrap by the Chemistry Department of the University of Delhi has highlighted the urgent need to tighten the system of tracking and controlling the possession of such hazardous material. One can understand scrap dealers lacking awareness of what radioactive sources are and their hazards to health and environment. But it is hard to believe that members of a university science department could approve the auction of a radioactive device, flouting the guidelines of the Atomic Energy Regulatory Board (AERB) on safe disposal of such equipment after use. Admittedly, it was a 42-year-old apparatus that has been in disuse since 1985. What is shocking is that a ten-member ‘write-off committee,' comprising scientific members of the university and chaired by the head of the chemistry department, approved the disposal of the Co-60 source, along with other unused equipment of the department, in one lot; and the Vice-Chancellor gave his final approval swiftly.

To blame the deadly disposal on miscalculation, as the top university authorities have done, is to add insult to injury. Calculating the left-over activity in any radioactive source over time is a simple task. Co-60 has a half-life of 5.27 years, which means its activity goes down by half every 5.27 years. Forty-two years is eight half-life periods, which means the activity would have gone down only by 2 to the power of 8, which is 256. The source in question, a GammaCell 220 Irradiator supplied by the Atomic Energy of Canada Ltd, was a very strong source with 3300 Curies(Ci) of initial activity. Depletion by a factor of about 250 after 42 years would still leave a huge amount of residual activity of a few hundred billion decays/sec. On paper, the AERB guidelines take care of the problem of radioactive sources across the length and breadth of the country. But the DU-Mayapuri case has shown how lax observance and enforcement of the rules are on the ground. The temptation to view it as an isolated case must be resisted. As this newspaper pointed out in a recent editorial, a number of ‘sealed sources' containing radioactive waste are turning up in scrap yards; U.S. Customs regulators in 2007 rejected several metal article shipments from India because they were found to be contaminated with radioactive material; and Germany, France, and Sweden have detected cobalt-60 in Indian steel. While we wait for the findings of the inquiry committee, serious lessons must be learned from the Delhi tragedy. The time for the government to clean up is now.

DU sole violator of radioactive norms: AERB
Dwaipayan Ghosh | TNN|New Delhi wrote:
Following the Mayapuri radiation leak, Delhi University has earned the dubious distinction of being the country’s only violator of radioactive waste disposal norms, according to the Atomic Energy Regulatory Board. That AERB alone is not raising fingers against Delhi University became clear after senior officers of Delhi Police claimed that even after repeated requests to the authorities, DU was yet to hand over important documents regarding the sale of the gamma cell.
According to police, DU is yet to respond to a number of important questions posed by the investigators. ‘‘We are waiting for some important documents after which we will consider action against the guilty,’’ said Sharad Aggarwal, DCP (west).
Officers at the police headquarters said they would soon forward a vital suggestion to the MCD and Delhi government regarding the safety of Mayapuri scrap market. ‘‘AERB and BARC had asked us to concretize the roads and bylanes of Mayapuri so that even the most minimal level of radiation — if still active in that area — can be countered. We will ask the government to take necessary steps,’’ said a police officer.
AERB, which is responsible for regulating and monitoring the safety of nuclear facilities and materials, said that more than 800 organizations had approached it in past five years for decommissioning nuclear material. “There are no reported cases of disposal of radioactive material in violation of the ‘Atomic Energy (safe disposal of radioactive waste) Rules, 1987,’ except the gamma cell that was auctioned by DU,” AERB said in an RTI reply to applicant, Abhishek Shukla.
