TIME HISTORY ANALYSIS FOR ISOTOPIC COMPOSITION OF ACTINIDES INHALED BY MAYAK PA WORKERS DURING 1949-2000
The method to estimate <sup>241</sup>Pu isotope content using the data of repeated <sup>241</sup>Am measurements is proposed. Calculations based on the data of repeated radiochemical analysis of skeleton tissue samples showed that <sup>238</sup>Pu and endogenous <sup>241</sup>Am relative contribution to dose patterns due to incorporated actinides increases with time.
