本试验是利用示踪方法,探讨在含盐地下水补给下,土体和地下水盐分运行的规律。试验方法:供试样品为含有0.5%放别性碘化钠的砂柱和含有5克/升放射性硫酸钠的溶液(模拟地下水)。利用马立奥瓶控制地下水埋深在80厘米和60厘米。测量方法采用一组四个定标器和钟罩计数管同时观测数点,因S~(35)为弱β源,为玻璃所吸收,所测的数值只是I~(131)(γ射线)运行状况。试验开始记录时间
This experiment is to use tracer method to explore the law of the salinity movement of soil and groundwater under the condition of salt groundwater recharge. Test Methods: The test sample was a sand column containing 0.5% sodium dodecyl iodide and a solution containing 5 g / L sodium sulfate radioactive (simulated groundwater). The use of Mario bottles to control groundwater depth of 80 cm and 60 cm. The measurement method uses a set of four scaler and bell counting tube to observe several points at the same time. Because S 35 is a weak β source absorbed by the glass, the measured value is only I 131 (γ ray) Health status. Test began to record time
