中文摘要 |
本文介绍的测量地下水中222Rn的液体闪烁法,具有简便、快速、灵敏、可靠等优点。该方法仅需水样10ml,制样时间不超过1min,探测限可达0.82Bq/L,能实现样品测量的自动化。它不需要特殊的测量装置,普通的商品液体闪烁计数器即可满足要求。是一种进行大规模地下水样中222Rn浓度调查的,较为理想的方法。 |
英文摘要 |
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 levels in groundwater. |
