John Dunn, MD, JD: The United States Environmental Protection Agency (USEPA) 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 (HPS) 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. https://junkscience.com/wp-content/uploads/2020/06/Health-Physics-Paper-edited-July-28-2018.pdf

Howard Cork Hayden, Emeritus Physics Professor, University of Connecticut: This presentation is about the Direct Proportion Model (aka LNT). It focuses on the horizontal axis (dose). Dose is an intensive variable, not an additive quantity (collective dose corollary). It presents extensive and intensive variables in language of thermodynamics. Radiation Dose is not an additive quantity. Use the Dose axis with great care. There are discoveries to be made when researchers abandon the notion that dose is an additive quantity.

Anything taken in excess can be harmful; aspirin is a good example. Thus, the adverse health effects of high doses of ionizing radiation at high dose rates do not predict possible harmful effects from low doses or low dose rates of (ionizing) radiation. Repeated studies have tried and failed to detect harmful effects caused by low doses or low dose rates of radiation. On the contrary, studies have found beneficial health effects. By ignoring such studies and extrapolating the effects of high doses of radiation at high dose rates, advisory bodies have concluded that low dose rates and low doses of radiation increase the risk of cancer. They are wrong.
