The results of a survey of underwater disposal sites of potentially hazardous objects in the Kara Sea and Oga, Tsivolky, Stepovoy and Abrosimov Bays are presented. Radionuclide levels were determined, using gamma-spectrometric and radiochemical methods, in zones near to and remote from buried solid radioactive waste in the outer and inner parts of the Bays. At the repository of the solid radioactive waste containers in the inner part of the Stepovoy Bay and Abrosimov Bay, higher than background concentrations of (137)Cs were determined in samples of bottom sediments. At one of the sites located in the Stepovoy Bay (137)Cs and (60)Co were detected.
本文介绍了对喀拉海以及奥加湾、齐沃尔基湾、斯捷波沃伊湾和阿勃罗西莫夫湾潜在危险物体水下处置场的调查结果。利用伽马能谱法和放射化学方法，测定了海湾内外靠近和远离掩埋固体放射性废物区域的放射性核素水平。在斯捷波沃伊湾和阿勃罗西莫夫湾内部的固体放射性废物容器储存库中，底部沉积物样本中测得的（137）铯浓度高于背景值。在斯捷波沃伊湾的一个地点检测到了（137）铯和（60）钴。
