Alpha-radiator distribution in the skin and body for contamination of various types

To evaluate the hazard of skin contamination with dry salts of α-radiators (210Po, 241Am and 237Np) and their solutions, experiments have been made on sucking-pigs, whose skin by its morphological and functional features resembles that of a man. It has been found that after 6-hour contact in the absence of sanitary treatment, the distribution of the radionuclides in the upper layer of the skin (100 μm) is practically the same for both kinds of contamination. In deeper skin layers and in the organism the content of nuclides studied deposited in the form of the dry salts is 1.5-7 times higher in comparison with the skin and organism contamination with a solution which is connected with the pH value of contaminant. The results obtained probe the necessity of proper hand skin protection in activities with 210Po and transplutonium elements and that of early skin decontamination, no matter what kind of contamination is
