A low-cost delta underwater gamma system (DUGS) for in-situ measurement of natural radionuclides in aquatic sediments

In this paper, we report on the design and radiometric performance of the delta underwater gamma system, a low-cost modular, waterproof, mobile detector system that we recently developed. Radiometric performance tests indicate that the SS316 enclosure can withstand impact from rock outcrops and debr...

More Information
Summary:In this paper, we report on the design and radiometric performance of the delta underwater gamma system, a low-cost modular, waterproof, mobile detector system that we recently developed. Radiometric performance tests indicate that the SS316 enclosure can withstand impact from rock outcrops and debris, with approximately 10% radiation absorption reported (14% at 351 keV and 8% at 1764 keV), implying minimal information loss. There is no significant difference in measurements obtained when the detector is operated vertically or horizontally. From the preliminary in-situ measurements, the system is sensitive to natural radionuclide variability in aquatic sediments.
