The calculated data are well in accord with the results of actual measurements of the contents of radionuclides in the body. Internal irradiation of all tissues and organs, determined by the inhalation of a mixture of radionuclides, worked almost completely within the first year following the accident, the thyroid being the critical organ. In the next years internal irradiation for the personnel of the Chernobyl Nuclear Power Station was determined entirely by transuranic elements and was about 0.1 M.P.D annually for bone tissue.
