The 14C emissions from NPP with RBMK-1000 and EGP-6 reactors as well as the yearly population irradiation dose due to these emissions are evaluated. A model is presented for calculating the population irradiation dose due to 14C emissions assuming an equilibrium 14C distribution between local food products and atmospheric air and absence of such an equilibrium for humans as a result of the consumption of imported food products. This model makes it possible to legitimately reduce the conservatism of the evaluation of the dose from standard NNP emissions as compared with the operating procedures and recommendations. The estimated population irradiation dose from 14C emissions is as follows, μSv/yr: 2.3 Smolensk, 1 Leningrad, 1.3 Kursk, and 0.034 Bilibino NPP. Irrespective of the computational model the 14C contribution in the total population irradiation dose due to emissions from NPP with RBMK-100 and EGP-6 reactors is significantly higher than 1%, so that it must be normalized and monitored.
