| Abstract: | A liquid scintillation counting method for determining 222Rn in groundwater is described in this paper, the method proved to be simple, rapid, sensitive and reliable. Only 10 mL of water sample is needed for the analysis. Sample preparation can be finished in less than one minute, the detection limit is about 0,82 BqL-1 Sample counting can be done automatically. A commercial liquid scintillation counting system is effective enough for the procedure. It. proved to be an idcal method for conducting large-scale survey on 222Rn le- vels in groundwater. |
