Governments and/or regulatory authorities are responsible for, among other things, the definition of regulatory controls or conditions, if any, that should be applied to radioactive sources or radiation exposure situations in order to appropriately protect the public, workers and the environment. Countries use different policy and structural approaches to fulfil this responsibility. Generally, the recommendations of the International Commission on Radiological Protection (ICRP) are used as at least part of the basis for protection. Now, with the evolution of recommendations from the ICRP, a single, conceptually simple, and self-coherent approach can be used by governments and regulatory authorities to define appropriate protection under all circumstances. This report describes this process.
