Abstract (English):
This study quantitatively compares 239Pu microdistribution in lung of two deceased former Mayak PA workers who were exposed to 239Pu by inhalation and two deceased subject who had been never employed at Mayak PA. The comparison is made utilizing neutron-activation method of measurement. The results are compared to the results of less-sensitive autoradiographic method. The study demonstrated that the most of 239Pu activity in lung is concentrated in areas of interstitial sclerosis.
