Howard Cork Hayden, Emeritus Physics Professor, University of Connecticut: The article in Nuclear News (Sept. 17, 2017) by Jerry M. Cuttler and William H. Hannum about the linear-no-threshold (LNT) model shows that not only are the no-threshold and collective dose aspects wrong, but that low-dose radiation has beneficial effects. For almost all cases, the Linear No-Threshold and Collective Dose radiation safety guidelines are based entirely on the notion that exposure is an additive quantity. It is not.

Evidence low dose rates increase dog lifespans (Jerry Cuttler, Ludwig Feinendegen, Yehoshua Socol) Canada Germany Israel13.Mar.2017
Jerry Cuttler, Ph.D. Nuclear Sciences and Engineering, past president of Canadian Nuclear Society. Ludwig Feinendegen, MD, Professor Emeritus, Heinrich-Heine Universität, Director of the Institute of Medicine at Kernforschungsanlage, Juelich. Yehoshua Socol Ph.D. Experimental High-Energy Physics, Executive Analyst, Falcon Analytics: After the 1956 radiation scare to stop weapons testing, studies focused on cancer induction by low-level radiation. Concern has shifted to protecting “radiation-sensitive individuals.” Since longevity is a measure of health impact, this analysis reexamined data to compare the effect of dose rate on the lifespans of short-lived (5% and 10% mortality) dogs and on the lifespans of dogs at 50% mortality. .. .. If dogs model humans, this evidence would support a change to radiation protection policy. Maintaining exposures “as low as reasonably achievable” (ALARA) appears questionable.
James Conca, contributing scientist to Forbes. Background radiation across the Earth varies from 3 mrem/yr (0.03 mSv/yr) over the oceans to 10,000 mrem/yr (100 mSv/yr) in areas of high elevation made up of granitic rocks. Thus, it is not surprising that populations subjected to radiation levels of 10,000 mrem (100 mSv) or below, either natural or man-made, show radiation effects that are not statistically different from zero.
