The International Commission on Radiological Protection (ICRP) publishes guidance on protection against radon exposure in homes and workplaces. ICRP Publication 137 recommends a dose coefficient of 3 mSv per mJ h m−3 (~10 mSv WLM−1) to be used in most circumstances of radon exposure, for workers in buildings and in underground mines. Recently, United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) reviewed radon epidemiology and dosimetry and concluded that its established dose coefficient of 1.6 mSv per mJ h m−3 (5.7 mSv WLM−1) should be retained for use in its comparisons of radiation exposures from different sources in a population. This paper explains and compares the reviews of the scientific evidence from UNSCEAR and ICRP. It is shown that the UNSCEAR and ICRP reviews are consistent and support the use of the ICRP reference dose coefficients for radiation protection purposes. It is concluded that the ICRP dose coefficient should be used to calculate doses to workers.

氡和后代的有效剂量系数：对 ICRP 和 UNSCEAR 值的回顾

国际放射防护委员会 (ICRP) 发布了关于在家庭和工作场所防止氡暴露的指南。ICRP 出版物 137 建议在大多数氡暴露情况下，建筑物和地下矿井中的工人使用 3 mSv/mJ hm-3 (~10 mSv WLM-1) 的剂量系数。最近，联合国原子辐射影响科学委员会 (UNSCEAR) 审查了氡的流行病学和剂量学，并得出结论认为，应保留其确定的 1.6 mSv/mJ hm-3 (5.7 mSv WLM-1) 的剂量系数以用于其比较人群中不同来源的辐射暴露量。本文解释并比较了 UNSCEAR 和 ICRP 对科学证据的评论。结果表明，UNSCEAR 和 ICRP 的审查是一致的，并支持将 ICRP 参考剂量系数用于辐射防护目的。得出的结论是，应使用 ICRP 剂量系数来计算工人的剂量。
