The results of a determination of the concentration and dispersity of radioactive aerosols in the local zone of the Cover in spring 2011 are presented. Aside from aerosols - products of the accident at the Chernobyl NPP in 1986, technogenic I, Te, and Cs contained in the emissions from the damaged units of the Fukushima-1 NPP and spreading in the Northern Hemisphere were found. It was determined that technogenic I and Cs and naturally occurring Be and Pb were present on the carriers of similar activity median aerodynamic diameter <1 μm. It is shown that the content of radioactive aerosols - products of the accident at the Fukushima-1 NPP did not exceed the admissible concentration of radionuclides in air for the population and did not make a substantial additional contribution to the dose load to workers at the site of the Cover.
