This study investigates the seasonal variation in radioactive cesium (sum of '134Cs and '137Cs; hereafter radioactive Cs) concentrations in kokanee (Oncorhynchus nerka) within a pumped-storage power plant reservoir system, with particular f...
Full spectrum modeling of in situ gamma-ray detector measurements with a focus on precipitation-induced transients [0.03%]
考虑降水引起的脉冲的原位γ能谱的全光谱建模
M S Bandstra,J M Ghawaly,D E Peplow et al.
M S Bandstra et al.
Gamma-ray detectors that are deployed outdoors experience increased event rates during precipitation due to the attendant increase in Rn-222 progeny at ground level. The increased radiation due to these decay products (Pb-214 and Bi-214) ha...
