Spectrometry analysis of fumes of mixed nuclear fuel (U0.8Pu0.2)O2e samples heated up to 2,000с and evaluation of accidental irradiation of living organisms by plutonium as the most radiotoxic fission product of mixed nuclear fuel

The main results of the research described are the following: (1) following the research on the influence of mixed fuel fission products (radioactive isotopes being formed during reactor operation as a result of nuclear decay of elements included into the fuel composition) on living organisms, the authors determined the quantities of plutonium dioxide (РuO2) that penetrated into blood and lay in the pulmonary region, liver, skeleton and other tissues.
