Abstract:

The results of the study of distribution of Tl-208, Pb-212, Ac-228, Pb-214, Bi-214, Th-234, Ra-226, Pb-210, Cs-137, Be-7, and K-40 isotopes in samples of atmospheric aerosol from the southern, central, and northern parts of Tajikistan are represented. Significant correlations are found between the concentrations of isotopes Cs-137 and Th-234 (0.95), Cs-137 and Ra-226 (0.95), Ra-226 and Bi-214 (0.84), Ac-228 and Ra-226 (0.75), Pb-210 and Pb-214 (0.69), Ac-228 and Pb-214 (0.64), K-40 and Pb-212 (0.71), Cs-137 and Bi-214 (0.78), and Th-234 and Pb-212 (0.67). Concentrations between the concentrations of other isotopes are insignificant or inverse. The statistics for dust intrusions indicates that the concentrations of isotopes K-40, Cs-137, and Bi-214 are hundreds of times higher than the background pollution level, and of the remaining isotopes, up to tens of times.

Keywords:
