摘要

po是一种半衰期足够长的有害天然同位素,在环境过程中起着重要作用。用α光谱仪分析了越南岘港-广南地区48个样品,包括地下水(挖井、热水和钻井)和地表水(湖泊、河流和溪流)。210Po活性较低,平均值为0.15 ~ 4.58 mBq.L-1和1.34 mBq.L-1。地下水和地表水组之间210Po活性无显著差异。这些组的平均210Po活性分别为1.28 mBq和1.40 mBq。l - 1。研究区的地质条件、中性pH值和主要氧化条件支持了所选水源的低210Po活性。成人、儿童和婴儿因饮用含有210Po的水而产生的年平均有效剂量分别为1.15、1.21和2.94µSv。分别y-1。

Radiological risk assessment and characteristics of 210Po in selected water sources in Quang Nam and Da Nang, Vietnam
210Po, one of the harmful natural isotopes with a long enough half-life, plays a significant role in environmental processes. 48 samples, including groundwater (dug wells, thermal water, and drill wells) and surface water (lakes, rivers, and streams) in the Da Nang - Quang Nam region of Vietnam were analyzed by an alpha spectrometer. Relatively low activities of 210Po have been observed, whose mean values ranged from 0.15 to 4.58 and 1.34 mBq.L-1. There is no significant variation in 210Po activities between groundwater and surface water groups. The average 210Po activity of those groups is 1.28 and 1.40 mBq.L-1, respectively. The geological conditions of the study area, neutral pH values, and predominant oxidizing conditions supported the low 210Po activities in the selected water sources. Average annual effective doses for adults, children, and infants due to the consumption of water containing 210Po were found to be 1.15, 1.21, and 2.94 µSv.y-1, respectively.
