氡是天然辐射照射的重要来源,地下水系统的水中富含有较高浓度的氡。对水扰动或加温会加快水中氡的释放,并进入外界空气。温泉作为地热水,广泛应用于医疗、保健和洗浴等方面。本项目通过测量咸宁温泉水中氡含量,以及温泉场所空气中氡及其子体浓度,探讨温泉水在利用过程中氡的释放情况,以及对温泉场所室内外空气氡及其子体浓度和变化规律的影响,并对现场工作人员和疗养人员进行了剂量评价(表1、2和图1),结果如下。
Radon is an important source of natural radiation exposure, groundwater system is rich in water with high concentrations of radon. Disturbing or warming the water will speed up the release of radon in the water and into the outside air. Hot Springs as geothermal water, widely used in medical, health and bathing and so on. In this project, the radon concentration in the hot springs of Xianning and the concentrations of radon and its sub-bodies in the air of the hot springs are investigated to investigate the release of radon in the hot spring water and the concentration and variation of indoor and outdoor radon and its daughters The impact of the dose was assessed on site staff and health-care workers (Table 1, 2 and Figure 1) and the results are as follows.
