The objective of this study is to investigate the levels of radon gas and increase public awareness of its hazards to health in Bethlehem governorate- Palestine. The concentrations of radon-222 and radium- 226 in 79 different types of water samples were measured. The average values of radon and radium concentrations in tap water, rainwater, groundwater, and mineral water samples were 0.93 Bq/ℓ and 45.5 Bq/kg, 1.01 Bq/ℓ and 49.3 Bq/kg, 1.21 Bq/ℓ and 59.3 Bq/kg, and 0.60 Bq/ℓ and 29.2 Bq/kg, respectively. All the measured radon concentrations in the collected samples were within the limit of 11 Bq/ℓ established by UNSCEAR in 1982. The annual effective doses for ingestion and inhalation due to radon in water were calculated for adults, children, and infants using parameters introduced by UNSCEAR in 2000. The results show that there is no significant risk to public health from radon inhalation or ingestion through drinking water in the study region.
本研究旨在调查巴勒斯坦伯利恒省氡气水平，并提高公众对其健康危害的认识。测量了 79 种不同类型水样中的氡-222 和镭-226 浓度。自来水中、雨水、地下水和矿泉水样本中的氡和镭浓度平均值分别为 0.93 Bq/ℓ 和 45.5 Bq/kg、1.01 Bq/ℓ 和 49.3 Bq/kg、1.21 Bq/ℓ 和 59.3 Bq/kg、0.60 Bq/ℓ 和 29.2 Bq/kg。所有采集样本中的氡浓度均在 UNSCEAR 于 1982 年设定的 11 Bq/ℓ 限值内。利用 UNSCEAR 于 2000 年引入的参数，计算了成人、儿童和婴儿因水中氡摄入和吸入导致的年有效剂量。结果表明，研究区域内通过饮用水摄入或吸入氡气对公众健康没有显著风险。
