Barely a month after two workers were exposed to nuclear radiation at a power plant operated by the Nuclear Power Corporation of India Limited (NPCIL) in Rawatbhata area of Kota district in Rajasthan, four more workers faced a similar hazard last week. But officials have rubbished the panic caused by the incident saying “exposure to radiation is normal and is a way of life…Earlier on June 23, two contractual workers were exposed to tritium during maintenance at unit number five…it was found that the two were exposed to radiation beyond the investigation limits.
