LNT Theory: A Credible Middle Ground?

Abstract

This presentation will summarize pros and cons of the debate which has been proceeding in the radiation protection community concerning the 'correctness' of the linear-no-threshold (LNT) theory. We shall summarize in general terms the discussions at three recent international meetings where the topic has been discussed: IAEA/WHO meeting in Seville (November 1997) on Low Doses of Ionizing Radiation: Biological Effects and Regulatory Control; the Pacific Basin Nuclear Conference (Banff, May 1998); and the American Statistical Association (San Diego, June 1998) "Radiation and Health" meeting, this year on the topic Radiation effects at low doses. The issues are complex. Specific impressions will be provided from each meeting on how the debate is proceeding, and some general conclusions drawn.
