| pubmed-article:7550891 | pubmed:abstractText | Dynamics of 137Cs content in main types of animal production obtained in region of Russia contaminated as a result of the Chernobyl NPP accident, 1986, is described. Decrease of contamination of agricultural production during 1987--1992 was of not regular character. The most rapid decrease of 137Cs content in production was registered in the first post-accidental period which was connected with intensive realization of countermeasures in agriculture at that time. Half-life periods of 137Cs content (major dose-forming radionuclide) decrease in production for areas of Russia subjected to the most intensive contamination amounted of 1.6 to 4.8 years, as dependent on the scale of countermeasures carried out. | lld:pubmed |
