本标准规定了稀土、铌/钽、锆及氧化锆、锡、铅/锌、铜、钢铁、钒、磷酸盐、煤、铝、钼、镍、锗、钛、金等非铀（钍）矿产资源开发利用活动中伴生放射性物料贮存及固体废物填埋设施在选址、设计、建设、运行、关闭、监护等过程应遵守的辐射环境保护原则与一般技术要求。其他非铀（钍）矿产资源开发利用活动可参照执行。
铀（钍）系单个核素活度浓度大于400Bq/g 的伴生放射性物料贮存及固体废物处置，应根据实际情况采取更为严格的环境保护措施。
Introduction
Analysis of the core content of the standard
| Management links | Key indicators | Special requirements |
|---|---|---|
| Site selection | Distance between foundation layer and groundwater ≥3m | Avoid active fault zones/hundred-year flood lines |
| Impeccable system | Permeability coefficient of double artificial lining ≤1×10-12cm/s | Thickness of primary and secondary linings ≥2.0mm |
| Monitoring period | Regular monitoring for 30 years | Detection of Radon Emission Rate/γ Dose Rate |
Detailed Explanation of Key Technical Terms
4.1.3 Three Simultaneous Principles
Pollution prevention and control facilities must be designed, constructed and put into operation simultaneously with the main project. Typical case: A rare earth smelter built a tailings reservoir with an anti-seepage coefficient of 1×10-12cm/s.
6.2.4 Anti-seepage System Architecture
Implementation recommendations
- Materials with uranium activity > 400Bq/g need to have their protection levels upgraded
- Landfills should be equipped with a leakage detection layer (Clause 6.2.6)
- Establish an electronic record system for radioactive waste
Analysis of standard evolution
Compared with GB 23727 uranium ore standard, this specification innovatively proposes:
- Expand the applicability to 16 types of non-uranium ores
- Clarify the technical parameters of double artificial lining
- Introduce a 30-year monitoring period system
