1.1本指南的目的是为确定设备、构筑物和陆地区域的剂量限值和残余放射性污染水平之间转换的现场特定转换系数提供指导。本指南不认可允许残留放射性污染的具体水平，也不提供人口剂量计算方法。 1.2规定退役核设施或场地和/或受放射性材料污染的私人财产的剂量限制的标准对于确定退役方法、指导清理（补救行动）工作、确定清理成本、确定待处理的放射性废物量和保护公众是必要的。 然而，此类标准尚未适用于所有类型的核设施、场地或财产。美国核管理委员会（NRC）管理导则1.86（1）， 以及环境保护局（EPA）和能源部（DOE）的具体颁布，提供了一些具体的指导。 1.3本指南无意制定这些联邦政策。它们将由环境保护局和其他联邦机构颁布。相反，它将作为可接受方法的指南，用于将尚未确定的剂量限值转换为退役后可留在现场的残余放射性材料的允许水平。 1.4本标准无意解决与其使用相关的所有安全问题（如有）。 本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 The purpose of this guide is to provide guidance in determining site-specific conversion factors for translating between dose limits and residual radioactive contamination levels on equipment, structures, and land areas. This guide does not endorse specific levels of allowable residual radioactive contamination, nor does it provide a methodology for population dose calculations. 1.2 Standards prescribing dose limits for decommissioned nuclear facilities or sites and/or private properties contaminated with radioactive materials are necessary to identify decommissioning methods, guide cleanup (remedial action) efforts, determine cleanup costs, identify the amount of radioactive waste to be disposed, and protect the public. Such standards, however, are not yet available for all types of nuclear facilities, sites, or properties. Regulatory Guide 1.86 of the U.S. Nuclear Regulatory Commission (NRC) (1), as well as specific promulgations of the Environmental Protection Agency (EPA) and the Department of Energy (DOE), provide some specific guidance. 1.3 This guide is not intended to establish these federal policies. They will be promulgated by the EPA and other federal agencies. Rather, it is to serve as a guide to acceptable methodology for translating the yet to be determined dose limits into allowable levels of residual radioactive materials that can be left at a site following decommissioning. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
