摘　　要：选取不同α、β放射性核素作为水中总α、总β测定的标准源,探讨与分析选取标准源的适宜性。测量结果表明,水中总α、总β放射性测定中,分别选取241Am和40K作为标准源,探测效率较高,准确性满足要求。Selecting a different alpha, beta radionuclide as the standard source for the determination of gross alpha, beta in wa- ter, the suitability of the selected standard source was discussed and analysied. The results showed that 241Am and 40K as standard sources respectively, with higher accuracy of detection efficiency, could meet the requirements.
