Following the publication `Control of low-level radiation exposure: time for a change?', distributed by the International Radiation Protection Association (IRPA) and subsequently modified by the author, Roger Clarke, and published in the Journal of Radiological Protection (R Clarke 1999 JRP 19 (2) 107-15), the Society for Radiological Protection (SRP) formed a Working Party (WP) whose remit is to discuss the issues arising from the paper and to prepare a response on behalf of the SRP which is the IRPA Associate Society. The WP considered the paper in great detail and prepared a questionnaire on the 33 aspects considered most important. The questionnaire is attached as appendix 1, together with a compilation of the responses received. Appendix 2 contains additional proffered comment. The questionnaire was sent to approximately 1500 UK international members. Although there was only a 6% response, the views expressed were wide-ranging, reflecting the broad professional interests, industrial, medical, academic, research and regulatory, of the international membership. This paper is a distillation of the responses together with the views of the SRP Council and its partner societies in the UK. Incidentally, the questionnaire has been adopted by other countries as a tool to help guide their debate.
