2. Influence of discharges from nuclear power plants (CNPE)

2.1 Volumetric activities in air and associated effective doses

The volumetric activities of radionuclides present in the air as a result of atmospheric emissions from nuclear power plants are too low to be measured as part of routine monitoring. However, since 2012, they have been better quantified during specific measurement campaigns carried out by the French Institute for Radiological Protection and Nuclear Safety (IRSN).

Figure 5 shows the results of measurements of tritium and carbon-14 volumetric...
