Ecological Systems and Devices Annotation << Back Development and assay of in situ bottom sediment radiation monitoring method based on underwetergamma spectrometer with hpge I.V. Pyrkov, A.S. Korotkov, I.I. Tihonov A.S. Semenovykh A non-destructive method for radiating monitoring of bottom sediment, based on application submersible semi-conductor gamma spectrometer is developed. The method has a series of advantages in comparison with widely applied sampling method. The method is successfully approved through monitoring of bottom sediment of water objects around an arrangement of the Novovoronezh NPP. Key words: radiation monitoring; bottom sediment; remote method; sampling method; specific activity; radioactive nuclide. E-mail: iitihonov@yandex.ru
