Scope

This Standard specifies the limit requirements of natural radioactive in
non-ferrous metal products, and over-limit of natural radioactivity activity
concentration and management control of artificial radionuclide pollution.
This Standard applies to development and utilization of non-ferrous metal
products such as copper, lead, zinc, tin, nickel, and cobalt. The development
and utilization of other minerals can also refer to the provisions of this
Standard.
