1.1本指南涵盖了在去污和退役（D）过程中遇到的材料放行获得批准的技术∧和D） 限制使用。它适用于因放射性含量而不符合任何监管要求的材料。图1显示了确定可考虑放行的材料的逻辑图。协商该逻辑树的材料被称为“基于剂量的释放候选材料” 1.2本指南的目的是提供一种方法，用于区分必须小心隔离以防止人类接触的材料与可回收或以其他方式处理的材料。它适用于放射性在材料体积中或多或少均匀分散的材料（称为块状残余物），而不是表面污染物体。 1.3表面污染物体是指外部受到放射性物质污染的材料。如果可以证明其符合适用的联邦和州表面污染法规，则已存在释放回收的规定。管理导则1.86和能源部第5400.5号令规定了释放供非限制使用的材料的放射性表面污染的上限。 1.4释放含有残余放射性物质的材料（除 226 Ra）散装（例如，土壤或轻微活化金属）是基于通过most证明公众成员的剂量将低于其预期用途的规定值（由申请人提出或由未来法规确定），并低于第二个规定值（也由申请人提出或由未来法规确定）限制性似是而非的场景。 第一个建议值应低于第二个值，因为对任何公众成员的剂量（通过预期用途场景）几乎肯定会实现，而替代场景的剂量只有在出现意外（可能不太可能）情况时才会累积。联邦法规已经存在，用于发布 226 Ra污染土壤。 1.5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 This guide covers the techniques for obtaining approval for release of materials encountered in decontamination and decommissioning (D∧and;D) from restricted use. It applies to materials that do not meet any of the requirements for regulatory control because of radioactivity content. Figure 1 shows the logic diagram for determining the materials that could be considered for release. Materials that negotiate this logic tree are referred to as "candidate for release based on dose." 1.2 The objective of this guide is to provide a methodology for distinguishing between material that must be carefully isolated to prevent human contact from that that can be recycled or otherwise disposed of. It applies to material in which the radioactivity is dispersed more or less uniformly throughout the volume of the material (termed residual in bulk form) as opposed to surface contaminated objects. 1.3 Surface contaminated objects are materials externally contaminated with radioactive material. Provisions already exist for their release for recycle if it can be shown that they meet applicable federal and state regulations for surface contamination. Regulatory Guide 1.86 and DOE Order 5400.5 specify the upper limits for radioactive surface contamination on material to be released for unrestricted use. 1.4 The release of material containing residual radioactive material (except for 226 Ra) in bulk form (for example, soil or slightly activated metal) is based on the demonstration that the dose to a member of the public will be lower than a specified value (proposed by the petitioner or to be determined by future regulation) for its intended use and lower than a second specified value (also proposed by the petitioner or to be determined by future regulation) via the most restrictive plausible scenario. The first proposed value should be lower than the second since the dose to any member of the public (via the intended use scenario) will almost certainly be realized, whereas the dose from the alternate scenario will only accrue if an unintended (and presumably less probable) circumstance arises. Federal regulation already exists for the release of 226 Ra contaminated soils. 1.5 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.
