Summary

The kinetics of contamination of a ground stratum of atmosphere in a short-range region of a plant "Ukryttya" is investigated during work on building new safe confinement. Weather influence, a type and a venue of operations on volume activity 137Cs in air is shown. It is displayed that absence of excess of admissible densities 137Cs in air during observations in sampling points does not guarantee absence of such overflows in venues of operations and in the propagation direction of a torch of local emission. The conservative assessment of volume activity of isotopes of the plutonium, executed in the conjecture of a fuel compound of "hot" particles, has displayed that the probability of local and short-term exceeding of admissible densities of isotopes of plutonium in 30 times exceeds probability of such overflows for 137Cs.

Keywords: object "Ukryttya", building a new safe confinement, specific activity of air, autoradiography, dissolution kinetics in a pulmonary fluid.
