摘要：
The temperature plays an important role in performance of the gamma densitometer system and can lead to inaccurate results. In order to investigate the effects of temperature, we used our gamma densitometer that is composed of NaI(Tl) crystal, photomultiplier tube (PMT), high voltage (HV) power supply, single channel analyzer (SCA) and Cs-137 source. In this paper, we consider the effect of temperature on crystal-PMT, SCA, HV power supply separately and on performance of gamma densitometer itself. Then acquired data were corrected to compensate the temperature effects by proposed method which improves system accuracy up to three times.
