The Delhi police today filed a chargesheet in a city court against six Delhi University professors in the 2010 Mayapuri radiation case for endangering lives by auctioning a radioactive gamma irradiator without following mandatory precautions. The chargesheet, filed before Metropolitan Magistrate Lovleen, covers Delhi University teachers, including the then Head of Chemistry Department, VS Parmar, and the then Dean of Sciences, Roop Lal. Besides them, Rakesh Kumar, Ramesh Chandra Rastogi, Ashok Prasad and Rita Kakkar have also been chargesheeted under various penal provisions dealing with causing death by rash and negligent acts and causing grievous hurt. The court is likely to take cognisance of the probe report on September 21. The irradiator was sold in the scrap market in violation of the rules of the Atomic Energy Regulatory Board (AERB) which says any chemical product emitting radiations cannot be auctioned and disposed of without following mandatory regulations, the chargesheet said. One person died and seven people were critically injured in April last year after they were exposed to radiation when they cut open a Cobalt-60 irradiator at Mayapuri scrap market here. The irradiator was traced to the university’s chemistry department. The police said two committees, comprising university professors, were set up before the irradiator was decided to be auctioned. The first committee was set up to find out which material was of no use to the university and can be sold and the second committee was formed to auction the waste products, the chargesheet said. The six accused professors were part of those committees and had recommended the auctioning, it said. — PTI
