利用液体闪烁测量装置，采用切连科夫计数法测量１８８Ｒｅ放射性活度。确定了１８８Ｒｅ的从本底到１０６Ｂｑ活度范围的放射性活度刻度曲线，用于１８８Ｒｅ放射性活度的准确测量。并且对一些影响测量效率的因素，如样品体积、测量瓶类型、样品溶液的介质等进行了观察。结果表明：在水溶液中，不加入波长转移剂，１８８Ｒｅ切连科夫计数效率达５８％。 Using the liquid scintillation measuring apparatus, the radioactivity of 188Re was measured by the method of Chernobyl counting. A calibration curve of activity of 188Re from background to 106Bq activity was established for the accurate measurement of 188Re activity. And some factors that affect the measurement efficiency, such as sample volume, measuring bottle type, the sample solution of the media were observed. The results show that 188Re Cherenkov counting efficiency is up to 58% without addition of wavelength-shifting agent in aqueous solution.
