Development of an Underwater Nal(Tl) Scintillation Spectrometer to Monitor Seabed Radioactivity

摘要

There was a positive correlation between the ~(137)Cs counts detected with S-RAM and the radioactive caesium concentrations in sediments. The S-RAM was able to detect the in situ radioactive caesium distribution of in sediments in the seabed at Nakoso. The results confirm that this detector is suitable for measuring the radioactive caesium concentrations along transects on the seabed.
