引言 在铀矿床的放射性水化学普查中,常采用水中铀和氡作为找矿标志。多年来,没有实地测量水中氡的仪器,用水样瓶从遥远的山沟取回水样,在室内采用FD-103型静电计进行测量。由于氡的寿命短,水样瓶不易密封而漏气,因而在室内所测数据不够准确。同时该仪器笨重、漏气、漏电,本底不易排除,操作繁琐,工作效率低。在高氡样品和气候潮湿的情况
Introduction In the uranium deposit radioactive chemical survey, uranium and radon in water are often used as prospecting indicators. Over the years, there have been no field-based instruments for measuring radon in water, water samples were taken from remote ravines with water vials and measured indoors using a model FD-103 electrometer. Due to the short life of radon, water bottle is not easy to seal and leak, so the measured data indoors is not accurate enough. At the same time the instrument bulky, leakage, leakage, the background is not easy to rule out, cumbersome operation, low efficiency. Humidity in high radon samples and climatic conditions
