人类接受电离辐射照射的主要贡献来自天然辐射源,包括外照射和内照射。本文旨在简要介绍联合国原子辐射效应科学委员会(UNSCEAR)1986年对世界正常辐射本底地区天然辐照年剂量的最新估算值,并与其前一次估算值进行了比较。一、历史的回顾联合国原子辐射效应科学委员会自1955年成立以来,为联合国对原子辐射的对策提供辐射水平和效应方面的科学资料,每年向联合国大会报告并每隔数年公布一次附有详细科学资料作为附件的较全面的报告书。这一系列报告书自1958年开始以来,1962、
The main contribution of human exposure to ionizing radiation comes from natural sources of radiation, including external and internal radiation. The purpose of this paper is to provide a brief overview of the 1986 annual UNSCEAR natural radiation dose estimates for the world’s normal radiation background and to compare them with their previous estimates. I. Historical Review The Scientific Committee on the Effects of Atomic Radiation in the United Nations has provided scientific information on the level and effect of radiation to the United Nations on the measures against atomic radiation since its establishment in 1955 and reports to the UN General Assembly every year and every few years it publishes detailed scientific More comprehensive report as an annex. This series of reports since 1958, 1962,
