摘要: An effort has been made to optimize the counting time for low-level measurement of naturally occurring radioactive material (NORM) by considering standard deviation between activity values different photopeaks and error. It is observed that at lower time, relative (RSD) varies randomly, but attains a gradual trend with increasing also comes closure Therefore minimum NORM 238U 232Th would be required stabilize RSD values.
