Cs-137 contamination measurements of Techa River bank territory in Brodokalmak settlement
- RECOM Ltd., Moscow (Russian Federation)
Cs-137 contamination mapping (with a scale 1:2,000) of one square kilometer of the Techa River bank territory inside the Brodokalmak settlement has been carried out. The electron maps of Cs-137 contamination distribution of bank landscapes have been created. Collimated scintillated detector technique was used for Cs-137 stock measurements. This method allows for determination of the total Cs-137 stock and the thickness of the soil layer containing more than 80% of total stock in-site. The RKG-09N device was used for these measurements. The Cs-137 contamination is very heterogeneous and the stock means are 10{sup 7} Bq/m{sup 2} at some places. The comparison of the above-mentioned technique and the traditional sampling method was carried out at specially chosen places. The gamma spectrometer laboratory data are in good agreement with site data. Additionally, the samples were investigated to determine soil surface activity of Sr-90. It was shown that Cs-137 contamination correlates with Sr-90 contamination within the bank territory of the settlement. The total Cs-137 stock contained at the investigated territory is near 6.6 {times} 10{sup 11} Bq. The estimated total Sr-90 stock here is near 2.2 {times} 10{sup 11} Bq.
