« EPA accepts the recommendations in the BEIR VII and ICRP Reports to the effect that there is strong scientific support for LNT and that there is no plausible alternative at this point. However, research on low dose effects continues and the issue of low dose extrapolation remains unsettled. » Source : EPA Radiogenic Cancer Risk Models and Projections for the U.S. Population, U.S. Environmental Protection Agency, rapport EPA 402-R-11-001, avril 2011
« The concept of a tolerance dose involves the assumption that if the dose is lower than a certain value-the threshold value-no injury results. Since it seems well established that there is no threshold dose for the production of gene mutations by radiation, it follows that strictly speaking there is no such thing as a tolerance dose when all possible effects of radiation on the individual and future generations are included. » Cité par: Background material for the development of radiation protection standards, Staff Report of the Federal Radiation Council, Report No. 1, 13 mai 1960
