Introduction
Analysis of the core content of the standard
| Elements | Requirements of HJ 1148 | Differences in conventional acceptance reports |
|---|---|---|
| Monitoring scope | Material with uranium (thorium) series nuclide activity concentration >1Bq/g must be covered | Only focus on conventional pollutants |
| Report structure | 11 normative chapters + Appendix A | Usually 6-8 chapters |
| Special requirements | It is necessary to provide nuclide balance diagram and the implementation of the "three simultaneous" of radioactive pollution prevention and control facilities | No such special requirement |
Key Terms
Associated Radioactive Minerals: Clearly defined as non-uranium (thorium) minerals with a single nuclide activity concentration exceeding 1Bq/g in the uranium (thorium) series. This threshold is consistent with the GB 18871 protection standard.
Actual Application Case
During the acceptance of a rare earth smelting project, it was found that the activity concentration of thorium-232 in the tailings reached 3.2Bq/g. According to clause 3.1 of the standard, it was determined to be associated radioactive solid waste, and a special storage facility must be built in accordance with the requirements of Appendix A.4.2.3.
Technology Evolution Analysis
This standard has established a complete acceptance monitoring technology system for associated radioactive mines for the first time. Its innovations are as follows:
- Establish the nuclide balance analysis method (Clause A.3.5)
- Introduce the storage technical specification requirements of HJ 1114
- Clear the acceptance condition judgment standard (Clause A.7.1)
Implementation Suggestions
| Links | Operational Points | Common Problems |
|---|---|---|
| Monitoring Preparation | Key VerificationCertificate of calibration of γ dose rate meter and α/β surface contamination meter | Ignore the matching of instrument detection limit and standard limit |
| Report preparation | Must include a comparison table of radioactive pollution prevention and control facilities (A.4.1) | Missing comparison of design indicators and actual treatment efficiency |
Note: Acceptance monitoring should pay special attention to the selection of monitoring methods for radon and its progeny in airborne effluents (Clause A.8.1).
