Operational approaches to the optimisation of radiological protection continue to evolve at nuclear power plants. The continual improvement of protection has been greatly facilitated by the exchange of good practice and experience through the Information System on Occupational Exposure (ISOE).
With the forthcoming revision of the system of radiological protection, as recommended by the International Commission on Radiological Proctection (ICRP), the ISOE programme considered that it would be important and useful to document good operational practice to ensure that it is reflected appropriately in the new ICRP recommendations. This report is a compilation of practical examples of good practice in optimisation. It is intended to assist nuclear power plants in providing the most appropriate protection for the public and workers, and to highlight for the ICRP concepts that should be reflected in its new recommendations.
