Abstract:
A set of new operational quantities for external radiation protection was proposed in ICRU Report 95. The new operational quantities were designed to overcome the conceptual and technical shortcomings of the existing operational quantities, and to achieve a better estimation of the protection quantities. This paper introduces the development of operational quantities, and the changes in their definitions, calculation phantoms and the application scopes, so as to fully understand the significance of the changes in the new operational quantities, which can be used as a reference for the relevant professionals.
