Biodistribution of 239Pu

A radiometric study of organs and tissues by 34 workers involved into plutonium production and died due to different reasons showed that distribution of plutonium in human organism by its inhalation depends on physico-chemical properties of isotope compounds. By transfer of soluble compounds it deposits to a greater degree in skeleton and to a less degree - in liver and lungs, by transfer of insoluble compounds - in lungs. By solubility of different degree the distribution is of mixed type. Distribution of plutonium in lungs is irregular: maximum isotope concentration is observed in superior lobes or lymphoid, that one in skeleton - in thoracic vertebrae and cranium.
