Holders of an RSR (Radioactive Substances Regulation) open source permit, including disposal to the environment, are required to report annually to Natural Resources Wales (NRW) emissions of certain non-nuclear radioactive substances.
This emissions data is collated as part of a UK dataset and is reported to the OSPAR Commission. OSPAR is the mechanism by which 15 Governments and the EU cooperate to protect the marine environment of the North-East Atlantic.
