Summary

Short generalization of researches of physical and chemical characteristics of the radioactivity aerosol of the 30 km zone of the ChNPP spent by employees of department of safety and rehabilitation of environment of the Institute of the Problem Safety of the NPP of NAN Ukraine is presented. Results of measurements of volume activity of emissions from оbject "Ukryttya", their existential variability, are resulted the basic characteristics Chernobyl an aerosol both in premises of object "Ukryttya", and in its near zone were analized. Data on activity distribution on the sizes of particles during natural wind lifting are presented. In premises of object "Ukryttya" and in its near zone except hot particles of fuel structure registered малоактивные particles enriched 137Cs. Data on a kinetics выщелачивания радионуклидов from "hot" particles allow to define a solubility class 137Cs, 90Sr, 239+240Pu and 241Am in the investigated aerosols as class S (slow dissolution) for fuel particles and to carry solubility 137Cs in low-level active caesium particles to class F (fast dissolution).

Keywords: radioactive aerosol, "hot" particles, distribution on activity, solubility in lung fluid
