AN ENVIRONMENTAL NOBLE LIE, LINEAR NO-THRESHOLD (in Radiation, Biophysics, and Toxicology) NEEDS TO GO (John Dunn) USofA07.Oct.2018
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.
Linear No Threshold (LNT) Folly: An Economics Perspective on Nuclear Safety (Leon Louw, Bonne Posma) South Africa USofA07.Oct.2018
Leon Louw, lawyer, economist, Executive Director of Free Market Foundation in South Africa, Director - Regulatory Affairs for Nuclear Africa (Pty) Ltd and Bonne Posma, physicist, Chairman, Nuclear Africa (Pty) Ltd, Founder, Saminco (USA) specializing in electric propulsion systems for off-road vehicles and underground mining conveyances. The nature and risks of nuclear radiation are widely misunderstood from the most advanced society to the least sophisticated societies. Many view nuclear radiation as they view ghosts and spirits. People who fear what they regard as ominous phenomena generally have difficulty explaining why. This facilitates the promotion by scaremongers of irrational fear. During the era of nuclear weapons testing, radiation fear mushroomed. It endures despite the fact that, for over half a century, 450 water-moderated nuclear power plants delivered millions of terawatt hours of electricity without a single radiation fatality.
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.
Bruno Comby, President of Environmentalists for Nuclear: I discovered a new local radiation hot spot in France in nature (publicly accessible) near the former Areva uranium mine of Lodeve. The radiation count there goes up to 4.8 microSv per hour, that’s a 100 times more than in the middle of the Salagou lake, and 50 times more than the usual background radiation, but still 20 times less than I measured inside an inhabited house in Ramsar near the Caspian sea.
