Intracellular incorporation of polymeric plutonium injected into mice was demonstrated in liver and spleen by electron-microscopic auto-radiography. The observations are not inconsistent with other evidence indicating the association of plutonium with lysosomal components. Early results with a quantitative electron-microscopic technique may lead to microdosimetry of cells and cellular components.
