Optimization in nuclear industry
Optimized procedures in the nuclear industry have reduced by more than 10 in thirty years the radiation exposures of populations, as can bec seen from the evolution of the local and regional collective dose received by the public. Considering that a gigawatt of power supplies electricity to about one million people in France, the individual exposure to radioactivity of a person due to the power plants operations and to the "uranium cycle" is now below one millionth of a sievert, that is about one-thousandth of exposures coming from health-care.
