ABSTRACT
This chapter extends in surveying some of the contexts for the pragmatic system. These include aspects of professional and clinical practice, including questions on uncertainties in radiation risk in both imaging and radiotherapy as detailed in the International Commission on Radiological Protection (ICRP) recommendations, in the regulatory framework, and in the radiation protection of patients in practice. The system of radiation protection in the great majority of countries in the world is based on the recommendations of the ICRP. The relationship between the ICRP principles and the principles/values of medical ethics is, at least on the surface, far from self-evident and requires much exploration. The regulatory framework for radiation protection in general and in medicine relies heavily on the recommendations of ICRP, but the structures and framework for implementation differ.
