| 内容記述 | The plutonium (Pu) treated in nuclear fuel cycle is usually accompanied with 241Am produced from 241Pu by b disintegration, which emits g-rays of 60 keV with the emission rate of 0.36, being more penetrable than the L X-rays from Pu. The 241Am could improve the detection limit of chest counting of Pu, if it being used as a metabolic tracer for Pu in lungs. Young adult male Wistar rats were exposed to polydisperse aerosols of Pu(NO3)4 with 0.6 mm in Activity Median Aerodynamic Diameter. They were periodically sacrificed and the radioactivity of 241Am and 238/239/240Pu in the autopsied lungs were measured. It has been shown that the 241Am was cleared from the lungs at nearly the same rate as the Pu at least for half a year post inhalation, which proved validity of 241Am as a metabolic tracer for inhaled Pu nitrate in external chest counting. | |||||
