种职业，以及医学检查、诊断和治疗程序。委员会1全面审查和评价这些来源在全球和各区域的辐照情况及相应的辐照剂量。根据对日本原子弹爆炸幸存者和其他遭辐射群体健康状况的各种研究，委员会对辐射引起的健康影响方面的证据进行评价。委员会还审查在认识辐射所造成的健康影响的发生机制方面所取得的进展。这些评估为国际辐射防护委员会（辐防委员会）拟订其关于辐射防护的建议以及为联合国系统内各有关机构制定《关于国际电离辐射防护和辐射源安全的基本安全标准》提供了科学依据。
therapeutic procedures. The Committee1 thoroughly reviews and evaluates global and regional exposures to such sources of radiation and the doses that result from them. It evaluates the evidence of radiation-induced health effects from studies of the health of survivors of the atomic bombings of Japan and of other exposed groups. It also reviews advances in understanding of the mechanisms by which radiation-induced health effects can occur. These assessments provide the scientific foundation used, inter alia, by the International Commission on Radiological Protection (ICRP) in developing its recommendations on radiation protection and by the relevant agencies within the United Nations system in formulating International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources.
