초록
A new underwater radiation monitoring system is developed and applied for measuringradioactivity using NaI(Tl) detector. The system consists of a detection module, a solar panel,and a bettery. The measurement data are tansmitted and received wirelessly. This apparatus isdesigned for qualitative and quantitative radionuclide detection in the water environment. Toevaluate performance of the system, long-term operation test was performed. To offer volumetricactivties in Bq·L-1, conversion factor of 137Cs is obtained using Monte Carlo simulations. Frombacground data and conversion factor of the system, the MDA of 137Cs for system was obtained tobe 1.78 Bq·L-1 for 5 minute measurement.
