John Cardarelli II, Captain US Public Health Service Officer, Cincinnati, OH, USA, Brant Ulsh, M. H. Chew & Associates, Livermore, CA, USA: The USEPA uses the linear no-threshold (LNT) model to estimate cancer risks and determine cleanup levels in radiologically contaminated environments. The LNT model implies that there is no safe dose of ionizing radiation; however, adverse effects from low dose, low-dose rate (LDDR) exposures are not detectable.
Mohn Doss, Medical Physicist in Diagnostic Imaging: The LNT Era (Linear No Threshold) has not ended yet. But, there are signs that we may be approaching its end. The problem with the LNT model for radiation-induced cancer is the absence of threshold results in the fear of the smallest amount of radiation. The LNT model was adopted by advisory bodies in the 1950 and has been endorsed by them repeatedly. Low-dose radiation boosts the immune system and so it should lead to reduction of cancers, a phenomenon known as radiation hormesis. Conclusion: The LNT mmodel is not valid and lives are being lost because of the LNT model and unjustified fear of low-dose radiation.
Donald Miller, MD: Fearful of the harm that radiation can do, the citizens of Sacramento, in a public referendum, had the city shut down its Rancho Seco nuclear power plant. The Sacramento Municipal Utility District put up windmills instead, which on a windy day produces 1 percent of the power the nuclear plant did.
Radiation-Response Models to Low Dose Protection Standards (American Nuclear Society, Health Physics Society, Alan Waltar) USA world08.May.2018
Alan Waltar, nuclear engineer, Past President of the American Nuclear Society, Chair ANS - HPS Joint Topical Conference on Applicability of Radiation-Response Models to Low Dose Protection Standards, October 1 - 3, 2018: Preliminary Program. This conference addresses one of the most important issues facing nuclear power and nuclear medicine, how to establish realistic low dose radiation protection standards. Since the beginning of use of nuclear power in the 1950s, the arbitrary Linear No-Threshold Model with Collective Dose Corollary has been used with results that vastly over predict deaths due to exposure to low dose radiation. This has added tremendous costs, held back the use of nuclear power and limited the use of nuclear medicine. This conference aims at working to establish a low dose protection standard that is based on reality of living organisms rather than an unrealistic arbitrary set of rules.
