Young adult male Wistar rats were exposed to polydisperse aerosols of Pu(NO3)4 with 0.6 mm in Activity Median Aerodynamic Diameter.

Americium (95 Am) is an artificial element, and thus a standard atomic weight cannot be given. Like all artificial elements, it has no known stable isotopes.The first isotope to be synthesized was 241 Am in 1944. 2021-03-19 · Lloyd RD, Mays CW, Jones CW, Atherton DR, Bruenger FW, Shabestari LR, Wrenn ME. Equations have been derived, from the results of total-body and partial-body counting and gamma-ray counting of individual bones and soft tissues, which describe the retention of injected 241Am in the liver, in the 2004-08-18 · Radioisotope Brief: Americium-241 (Am-241) (continued from previous page) August 18, 2004 Page 2 of 2 For more information on protecting yourself before or during a radiologic emergency, see CDC’s fact sheet 0.314 .

Kuzmenko This evaluation was completed in October 2002 and revised in January 2004. 241Am injection, and 7-day collections were made on a monthly or bimonthly schedule thereafter for about an additional 16 wk. The 241Am content of each excreta sample was determined by gamma-ray counting, and the retention of 241Am in the liver and in nonliver … 2014-08-01 Americium-241 and plutonium determinations will become of greater importance over the coming decades as 137Cs and 241Pu decay. The impact of 137Cs on environmental chronology has been great, but its potency is waning as it decays and diffuses.
