In 1993, ICRP-65 recommended that dose conversion of radon exposure should be based on the comparison of detriments between radon exposure and effective dose. The lifetime detriment from the radon exposure was projected according to the epidemiological studies of uranium miners then available. The projection model (GSF) was multiplicative with temporal and age-at-exposure modification. Since 1993, new studies of uranium miners have appeared and many original studies were updated. In addition, projections of the risk have been improved by including further modifying factors as for instance in BEIR VI. New analyses were completed in the Czech and French studies of uranium miners with accurate estimates of exposures based on extensive radon measurements. The resulting estimates of excess absolute lifetime risk per unit exposure in working level months (WLM) from these models lead to dose conversion of 10 mSv WLM(-1) for the BEIR VI model and 8 mSv WLM(-1) for the joint Czech-French model in contrast to the conversion of 5 mSv WLM(-1) for the GSF model.
1993年，国际放射防护委员会第65号出版物建议，氡暴露的剂量转换应以氡暴露与有效剂量之间的危害比较为基础。根据当时可得的铀矿工流行病学研究，推算出了氡暴露的终身危害。推算模型（GSF）是时间和暴露年龄修正的乘积形式。自1993年以来，出现了新的铀矿工研究，许多原始研究也得到了更新。此外，通过纳入更多修正因素，如在BEIR VI中那样，风险推算得到了改进。捷克和法国对铀矿工进行了新的分析，基于广泛的氡测量对暴露进行了精确估计。这些模型得出的每工作水平月（WLM）单位暴露的超额绝对终身风险估计值，使得BEIR VI模型的剂量转换为10 mSv WLM⁻¹，捷克 - 法国联合模型为8 mSv WLM⁻¹，而GSF模型的转换值为5 mSv WLM⁻¹。
