John Dunn, MD, JD: The United States Environmental Protection Agency is charged with identifying and mitigating environmental risks. This article discusses US EPA’s misguided decision to use the Linear-No-Threshold (LNT) cancer risk model as a basis for regulating exposure of the public to ionizing radiation such as is associated with residential radon. The Health Physics Society has stated that reliance on the LNT model “…tends to foment the public’s fear of all types of radiation . . . reliance on the LNT model, especially at very low doses and dose rates, is inappropriate and can exaggerate the risk.” The HPS also condemns “collective” (cumulative) dose as a measure of radiation health risk.

Howard Cork Hayden, Emeritus Physics Professor, University of Connecticut: This article was presented at the ANS - HPS Joint Topical Conference on LNT, Linear No-Threshold Model and Cumulative Dose. It is a straightforward proof that radiation dose is not a cumulative measurement.

Andrzej Strupczewski, Chairman of Nuclear Safety Commission at National Centre for Nuclear Research, Poland: Fear is dominating practically every discussion on consequences of the Fukushima accident. The largest earthquake ever noted in Japan’s history followed by a disastrous tsunami hit on March 11, 2011. Both these calamites destroyed the entire province, moved Japan isles by 4 metres (!) and killed almost 20,000 people. Reports of UN agencies (including World Health Organization and the UNSCEAR Scientific Committee) unanimously state that no health consequences have been or will ever be detected – even within Fukushima neighbourhoods most exposed to the radiation.

Mohn Doss, Medical Physicist in Diagnostic Imaging: 1) Low-dose radiation increases activation of natural killer cells. 2) Natural killer cells eliminate cancer cells, and so there would be less cancers following exposure to low-dose radiation.
