    Notes: Conclusion The results showed that plutonium may be retained in bone marrow macrophages for a considerable time. Consequently, plutonium deposits in these cells may substantially irradiate components of the surrounding bone marrow and cells on bone surfaces. In red bone marrow these include the radiation sensitive cells which give rise to leukaemia. If follows that bone marrow deposits of plutonium resulting from the turnover of contaminated bone are likely to be important in radiation protection dosimetry. The period of plutonium retention in the bone marrow was found to exceed that in the liver. In addition to the above the results of this study suggest that the autoradiographic methods used to measure the plutonium content of the bone marrow are likely to be suitable for studying those factors which may affect the rate of loss of alpha-emitters from this tissue. These factors include the iron status, sex, and age of the animal and effects of drugs and radiation on the cells.

    Notes: Abstract Studies were undertaken using bone removed from young adult baboons, which had been contaminated with plutonium-239 at various times prior to sacrifice, and human bone from an adult male (USTR Case 246), who had received an internal deposition of americium-241 as a result of a glove-box explosion 11 years prior to his death. The baboon bone was supplied by the CEA, France, and the human bone by the United States Transuranium Registry. The bone samples, examined by qualitative and quantitative autoradiography with CR 39 detectors, demonstrated the rapid redistribution of bone surface-seeking radionuclides in younger primates due to growth and the slower, bone turnover driven redistribution in the adult human bone. In both species, primary and secondary surface deposits of radionuclide remained conspicuous despite bone activity; true volumization of radionuclide was seldom seen. The dosimetric implications of these findings are discussed.
