Misleading statement on CNSC website about tritium risk

March 20th, 2009

In his recent letter to Canadian Nuclear Safety Commission on behalf of the Tritium Awareness Project, Dr. Gordon Edwards points out  that  the CNSC should remove from its web site this statement:

Radiation doses of 100 mSv [millisieverts] and more have shown increases in cancer incidence but there is no evidence of health effects at doses below about 100 mSv.

In his letter to CNSC President Michael Binder, Dr. Edwards says “The statement is scientifically incorrect and misleading. It suggests that a safe threshold of radiation exposure exists – a conclusion at odds with the widespread scientific consensus as found in many documents published by the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), the US National Research Council (NRC), and the International Commission for Radiological Protection (ICRP).
