Scope

This Standard specifies the active concentration for material not requiring
radiological regulation (hereinafter referred to as regulation-exempted
concentration).
This Standard applies to activities such as production operation, trade, landfill
or recycle of large amount (more than 1 ton) material. However, it does not
apply to the following conditions.
- Food, water, animal feed and any substances used in food or animal feed;
- Radon in the air (optimized action level of radon concentration in the air is
shown in Appendix H of GB 18871-2002);
- Material in transporting (managed according to transportation standard);
- Liquid and gas effluents generated by approved practice (they belong to the
scope of approved emission);
- Radioactive residues in the environment (including field soil).
