Bernard Cohen, Professor of Physics at the University of Pittsburgh and sometime President of the Health Physics Society, offered to eat a gram of plutonium oxide or breathe a liter of plutonium oxide particles that could stay suspended in air for one minute. He said the additional hazard would be equivalent to taking a six month sabbatical in Denver. Note that about 7 1/2 tons of plutonium were dispersed in the atmosphere by the atmospheric bomb tests of the US, USSR, Britain, France and China.
