Future application of the ICRP system of radiological protection: views from UK professionals

The Society for Radiological Protection (SRP) and UK Partner Societies have formed a working group to consider ICRP proposals for new recommendations, helping to formulate responses to ICRP from the International Radiation Protection Association. SRP views have been summarised under three headings: (1) Science; (2) Applications; and (3) Communications. (1) Small changes in low dose (< 100 mSv) risk estimates may not warrant detailed revisions. Proposed changes to ICRP dose quantities and ICRU operational quantities are generally welcomed. However, it is noted that the present system works well and such changes do not of themselves appear to warrant the publication of new ICRP general recommendations. (2) An important focus for the practical application of the system is the promotion of reasonableness in the optimisation of protection at low doses in different circumstances of exposure. Experience has shown that in many cases, application of the ALARA principle over-emphasises the ‘as low as’ without due consideration of the ‘reasonably achievable’ and the caveat of ‘taking economic and social factors into account’. (3) ICRP recommendations are aimed principally at regulatory authorities, organisations and individuals who have responsibility for radiological protection. There is scope for improved coordination of the efforts of RP organisations in the development of the system, its dissemination to RP professionals and its communication to stakeholders affected by the application of the system.
