August 31, 2010. Pick of the Week #8: Failed Attempt to Reduce Safety Code 6 Guideline in 1977.
Dr. Michael Repacholi, prior to becoming the Coordinator of the Radiation and Environmental Health Unit at the World Health Organization, was involved in formulating Canada’s Safety Code 6 Guideline for microwave radiation. In 1977, he and Maria Stuchly gave a talk at the I.E.E.E. meeting in Toronto entitled “Emission and Exposure Standards for Microwave Radiation.”
In this presentation Repacholi and Stuchly proposed a Canadian maximum permissible level (MPL) for microwave radiation that was between the then U.S. guideline (10 mW/cm2) and the Russian guideline (0.01 mW/cm2). The recommended MPL was 1 mW/cm2 for occupational exposure and 0.1 mW/cm2 for public exposure. These proposed guidelines are much lower than what we currently have (5 mW/cm2 for occupational exposure and 1 mW/cm2 for unlimited public exposure).
