Plutonium in environment; Plutonij v okruzhayushchej srede

Mass production of fission products and numerous testing of atomic and hydrogen bombs, imperfection technologies of chemical reprocess worked out of nuclear fuel, entering of high active radionuclides from numerous places of burial and all kinds of accident on equipment with using nuclear technologies, it is all are cause of entry in biosphere of radioactive transuranium nuclides from 7 to 10 now, mainly long-lived isotopes of plutonium. At present operating time of plutonium reliably evaluating on a level with 900-905 t. Already now content of technogene plutonium in upper layer of soil (to 30 cm) reaches to 10{sup -13} g/g in numerous locations. In this case the concentration in alive organisms compose non-less than 10{sup -14} g/g. Inevitably it will be grow on till dangerous level with 10{sup -12} g/g in zones with high level of pollution, which are dangerous for human health. Typical isotopic mass {sup 240}Pu/ {sup 239}Pu armored plutonium ratio compose 0.05-0.06. Measured isotopic mass {sup 240}Pu/ {sup 239}Pu analogous isotopic ratio of global fallen outs, shows, that followed by [{sup 240}Pu/ {sup 239}Pu]{sub from}[{sup 240}Pu/ {sup 239}Pu]{sub mj} 1 pollution of soil dependently by plutonium of irradiated fuel, for example, Chernobyl NPP. Inhalation ways of entrance plutonium is the greatest contribution (above 90 %) in dose of irradiation.
