Characteristic features of the Cs-137 and Sr-90 distributions in the floodplain of the Techa river near the village of Brodokalmak

Digital maps of the distribution of Cs-137 accumulation in the soil of the floodplain of the Techa river near the village of Brodokalmak are construct ed on the basis of more than 800 field measurements. The total length of th e surveyed section is greater than 15 km. The total accumulation and the ar ea of the floodplain, whose contamination corresponds to definite ranges of the surface activity values, are calculated for half-kilometer sections of the floodplain of the rivet: The specific activity of Sr-90 in the soil is measured at individual locations and its accumulation for sections of the floodplain near the village of Brodokalmak is estimated from the correlatio n coefficients. 5 figures, I table, 16 references.
