Technical indicator analysis
Radioactive contamination detection
When using channel-type radiation detection equipment, the alarm threshold setting must be ≤0.25μSv/h. The on-site implementation shall be in accordance with Appendix B:
- The background value measurement shall take the average of 5 points
- Manual inspection shall be no less than 3 stop points
- α pollution detection distance ≤1cm
Implementation suggestions
Key points for corporate compliance
- Classification and transportation of raw materials: Mixing of different types of bulk materials is prohibited
- Declaration specifications: Multiple types of recycled materials shall not be declared on the same customs declaration form
- Pretreatment requirements: The content of non-metallic coatings must be ≤5%
Standard evolution analysis
The 2024 version mainly responds to the update requirements of the National List of Hazardous Wastes and strengthens:
- New volatile matter detection method (Appendix C)
- Refine the calculation formula for the physical quantity of copper alloy (5.6.2)
- Clarify the requirements for technical equipment such as surface contamination meter
