In Japan, the clearance levels for uranium-bearing waste have been established by the Nuclear Safety Commission (NSC). The criteria for uranium-bearing waste disposal are also necessary; however, the NSC has not concluded the discussion on this subject. Meanwhile, the General Administrative Group of the Radiation Council has concluded the revision of its former recommendation 'Regulatory exemption dose for radioactive solid waste disposal', the dose criteria after the institutional control period for a repository. The Standardization Committee on Radiation Protection in the Japan Health Physics Society (The Committee) also has developed the relevant safety criteria and guidelines for existing exposure situations, which are potentially applicable to uranium-bearing waste disposal. A new working group established by The Committee was initially aimed at developing criteria and guidelines specifically for uranium-bearing waste disposal; however, the aim has been shifted to broader criteria applicable to any radioactive wastes.
在日本，核安全委员会（NSC）已制定了含铀废物的豁免水平。含铀废物处置标准也很有必要；然而，核安全委员会尚未完成对此问题的讨论。与此同时，辐射委员会的总务管理小组已完成对其先前建议“放射性固体废物处置的监管豁免剂量”（即处置库制度控制期后的剂量标准）的修订。日本健康物理学会辐射防护标准化委员会（该委员会）也已制定了适用于现有照射情况的相关安全标准和指南，这些标准和指南可能适用于含铀废物处置。该委员会新成立的一个工作组最初旨在专门制定含铀废物处置的标准和指南；然而，其目标已转向适用于任何放射性废物的更广泛标准。
