The purpose of this analysis is to determine the field screening countrateconversion and limitation values required when analyzing soil samples to determine if there are criticality concerns, potentially transuranic waste (TRU) quantities of plutonium present, or whether air sampling is required.Sitsler...

Biokinetics of Inhaled Plutonium-239 and Americium-241 Present in Contaminated Dusts at Maralinga The biokinetics of Pu and Am present in three dust samples obtained from the former nuclear weapons test site were investigated after their deposition in the rat lung. For the different dusts the rate...
The half-life of239Pu has been determined by specific activity measurements on solutions prepared from the stoichiometric compounds Cs2 PuCl6, using plutonium 99.03% enriched in239Pu. The value...doi:10.1007/BF02518350D. BrownK. M. Glover...
The specific activity is varied by changing the number of sources per g of tissue. The program also allows to calculate the numbers of cell nuclei with zero energy deposition. From the 1 dps point sources an average specific energy of 831 rads/h results for plutonium for cell nuclei within ...

Using the experimentally determined Pu/(Pu+Pu) alpha activity ratio, the alpha specific activity of Pu as well as the atom% abundances of different isotopes of plutonium can be obtained from these correlations, without performing mass spectrometric analysis of Pu sample. These correlations are ...
