A method for the measurement of gross alpha and gross beta activities for low alpha-to-beta activity ratios is presented. Measurement of the gross alpha activity would still be important from an internal dose perspective when the gross beta activity is dominating, since a significant dose contribution may come from alpha emitting radionuclides. The method is intended for screening of drinking water after a radiological emergency when many samples would be valuable to be measured during a short period of time.
本文介绍了一种用于测量低α/β活度比情况下总α和总β活度的方法。当总β活度占主导时，从内照射剂量角度来看，总α活度的测量仍然很重要，因为发射α粒子的放射性核素可能会产生显著的剂量贡献。该方法旨在用于放射性应急后饮用水的筛查，此时在短时间内测量大量样本具有重要价值。
