National Dose Assessment Working Group
The National Dose Assessment Working Group (NDAWG) was established to promote the use of best practice and consistent methodologies for assessing radiation doses from planned discharges of radionuclides to the environment. As part of its work, NDAWG published Guidance Notes and Reports on key topics relating to the assessment of discharges.
These documents were drafted by members of NDAWG Working Groups which included members from academia, the nuclear industry regulators and other government departments, non-governmental organisations etc. These documents contain public sector information licensed under the Open Government Licence v3.0.
The Society for Radiological Protection was not involved in the production of these documents and is not responsible for their contents. The Society is making them available as a service to the profession and the wider community. For further information about the NDAWG and its work please contact SRP.
