【摘要】 介绍了某天然蒸发池放射性废液蒸发量模拟实验、现场采样监测、释放源强估算方法及辐射健康危害评价的结果。估算表明:蒸发池运行所致最大个人年危险为6.5×10^-9;20km半径范围内总的集体年危险为3.2×10^-5人。文章指出,上述估算结果仅仅是针对一个运行年（即1990年）而言。如果考虑到地面放射性核素沉积的累积效应,则随着时间的推移,其危险会略有增加,直至达到一动态平衡为止。更多还原

【Abstract】 The results of simulated experiments, field monitoring and radiation health risk evaluation of radionuclides transport to the atmosphere from the natural evaporating ponds of a certain nuclear factory, and the estimating method of releasing source strength are presented. The estimated results of radiation health risk show that the maximum individual annual risk is 6.5X 10-9 and the total collective annual risk within a radius of 20 km is 3. 2 X 10-5 person, which are caused by operation of the evaporating ponds. It should be pointed out that the above estimated results only refer to one operating year (1990). If the cumulative effect of radionuclides deposition in ground is considered, the risk will increase a little with time until the dynamic balance is achieved.更多还原
