Zbigniew Jaworowski, Physician, Ph.D. and D.Sc. in Natural Sciences - About 2.3 billion years ago, the advent of an oxidative atmosphere stimulated the surviving organisms to develop efficient defences against the enormous flux of Reactive Oxygen Species (ROS) produced by metabolic processes. These powerful ancient defence mechanisms also protect against the DNA damage caused by low levels of ionising radiation, which is one of the smallest risks in the environment. The Linear No Threshold (LNT) model of the radiation effects appears inappropriate for the current needs.

Edward Calabrese, Professor of Toxicology at the University of Massachusetts, Amherst - The comments offered here assess the scientific foundations of 3 petitions (Carol Marcus, Michael Miller, and Mohan Doss) to the Nuclear Regulatory Commission (NRC) proposing a change in the use of the linear non threshold (LNT) for risk assessment to the hormesis dose–response. It will be shown how hormesis could be applied to cancer risk assessment and how this may be used to optimize the health of radiation-exposed workers and the general public.

Holman Jenkins, writer for the Wall Street Journal, Wade Allison, Emeritus Professor of Physics, Oxford University. A paradigm shift is necessary to facilitate use of nuclear power. This involve stopping use of unscientific radiation guidelines using the Linear No Threshold Hypothesis and basing radiation protection on long observed and documented facts about effects of radiation on living organisms. This article is written so everyone can understand. If we used the Linear No Threshold Hypothesis for guide lines in the rest of our lives, we would not drive cars or take baby aspirin, etc.
