The classification used during the decommissioning of nuclear installations for the activated materials of radiation protection made of concrete is validated. It is shown that in the decommissioning of nuclear installations the category of activated wastes that are formed, including owing to the large and sometimes determining contribution of 3H in the total induced activity of the concrete with decay times up to 100 years, can be interpreted loosely. The requirements of handling tritium-containing wastes have not been developed.
