Abstract
Results of the radioactive contamination measurements by Cesium-137 of a repository are evaluated. Contamination are carry out with hole radiometry near the repository. Vertical curves of exposure dose rate have a mutual feature — an absence of high values at low depths that corresponds to bulk layer of soils and sharp increasing of exposure dose rate in 60–80 cm that reflects an upper level of repository. Complex software MicroShield was used during data processing of gamma-ray log and specific activity of Cesium-137 determination in radioactive waste gatherings. Software functions with a wide range of geometry options give an opportunity to represent the exact conditions in the well. This allows us to increase the resolution of calculations, minimizing the possibility of possible uncertainties and determine radioactive characteristics inside the buried radioactive waste. Furthermore, determination of buried radioactive materials characteristic afford making rational administrative and projective decisions on how to safely eliminate and behave with radioactive waste.
