The present study concerns measurement of the radon concentration in drinking and irrigation waters obtained from the eastern part of Oman, in particular in regard to water quality assessment of the region. The samples were collected from different places covering most types of water sources in the region. A passive and time-integrated track etch detector (LR-115 type II) combined with a high-resolution optical microscope has been used to obtain the radon concentration in the studied samples. Values of dissolved radon in water varied among the water sources; the highest concentration of radon was found to be 363 Bq m-3 in a drinking water sample while well water used for irrigation showed the lowest value, at 140 Bq m-3. Measured data for all water sources are below the permissible limit of 11.1 kBq m-3 recommended by the US-EPA. Annual effective doses for the studied samples were in the range 0.38-0.99 μSv y-1 which is significantly less than the action level recommended by the WHO (0.1 mSv y-1), indicating that the water sources in the Jalan BBH region of Oman are safe to use. The obtained data may serve as a reference for any future radiological study of the waterbody of this region.

阿曼东部灌溉用水和饮用水中OF浓度的评估以及对阿曼有效剂量的估算。

本研究涉及从阿曼东部获得的饮用水和灌溉水中the浓度的测量,特别是在该地区的水质评估方面。样品是从覆盖该地区大多数水源的不同地方收集的。无源和时间积分的轨道蚀刻检测器(LR-115 II型)与高分辨率光学显微镜相结合,已用于获得研究样品中的concentration浓度。水中溶解ra的值因水源而异。饮用水样品中最高的of浓度为363 Bq m-3,而用于灌溉的井水最低,为140 Bq m-3。所有水源的测量数据均低于US-EPA建议的11.1 kBq m-3的允许极限。研究样品的年度有效剂量在0.38-0.99μSvy-1范围内,大大低于WHO建议的行动水平(0.1 mSv y-1),表明阿曼Jalan BBH地区的水源使用安全。所获得的数据可作为该地区水体未来任何放射学研究的参考。
