25-40% underestimate of radiation doses to 1,769 Canadian health care workers undetected for 4 years
The Star has reported that 1,769 Canadian health care workers suffered radiation doses 25 to 40% worse than they were told four years ago, due to an error in a computer program administered by Health Canada. The Canadian Nuclear Safety Commission regulates Health Canada on such matters, but both federal agencies missed the error for 4 years. Some health care workers were exposed to above permissible doses, once the error was caught. CNSC also regulates Canadian atomic reactors, and other nuclear facilities and activities. The article closed by quoting Mark Mattson of Lake Ontario Waterkeeper:
"Mark Mattson of Lake Ontario Waterkeeper, who has opposed construction of new nuclear units at Darlington, said the incident raises question about the nuclear regulator – which also oversees nuclear power stations.
'The shocking thing here is that no one noticed the mistake for four years,' he said.
'Waterkeeper is very interested to see who is held accountable for this mistake. In recent years, we have become increasingly concerned that the CNSC is lax when it comes to enforcing the rules.' "
