New results of radioactivity studies on bottom sediment samples of the Novaya Zemlya Depression of the Kara Sea
Object and purpose of research. This paper studies bottom sediment samples taken at nuclear waste disposal sites of the Novaya Zemlya Depression (the Kara Sea). The purpose of this study was to measure specific activity distribution of bottom sediments depth-wise, to identify dumped objects causing...
