A method to determine the 137Cs soil deposit in situ where the contamination is covered by a clean soil layer is described. The method is based on measurements of the count rates in three energy ranges by a collimated spectrum sensitive detector and their processing. The deposit determination accuracy is 20%. The measurement results are presented and(More)
137Cs contamination of the Techa river flood plain inside the Brodokalmak settlement has been mapped. The collimated scintillated detector technique was used for 137Cs deposit measurements. The 137Cs contamination is very heterogeneous. A comparison of this technique with the traditional sample method was performed at selected locations. The sampling data(More)
