Oi. Yaroshevich et al., DEVELOPMENT OF THE INSTRUMENTAL METHODS F OR RADIONUCLIDES OF PU AND AM-241 CONTENT CONTROL IN SOILS, Doklady Akademii nauk BSSR, 37(6), 1993, pp. 49-52
An instrumental method based on the registration of chi- and gamma-rad
iation of Pu and Am-241 in soils with high activity of other radionucl
ides of post-Chernobyl origin is described. The results of chi- and ga
mma-radiation spectra measurements with the help of this method as wel
l as the results of measurements of alpha-activity distribution with S
SNTD method of different types of soils as to their depth are presente
