Jerry Cuttler: Although almost 120 years of medical experience and data exist on human exposure to ionizing radiation, advisory bodies and regulators claim there are still significant uncertainties about radiation health risks that require extreme precautions be taken. In the `950s, without scientific evidence, the Natitonal Academy of Sciences Biological Effects of Atomic Radiation (BEAR) Committee recommended that the linear no-threshold (LNT) model be used to assess the risk of radiation-induced mutations in germ cells and the risk of cancer in somatic cells.

Background radiation across the Earth varies from 3 mrem/yr (0.03 mSv/yr) over the oceans to 10,000 mrem/yr (100 mSv/yr) in areas of high elevation made up of granitic rocks. Thus, it is not surprising that populations subjected to radiation levels of 10,000 mrem (100 mSv) or below, either natural or man-made, show radiation effects that are not statistically different from zero.

The first Earth Day, in 1970, was celebrated after a wave of environmentalism swept the nation. Many give credit to Rachel Carson's 1962 book, "Silent Spring," which popularized the notion of large-scale chemical pollution, for igniting the movement.The "linear model" assumes that just a single molecule of a carcinogen or a single ionization from an X-ray can induce cancer. The enthusiasm spawned by Earth Day soon gave us brand new regulatory agencies such as the Environmental Protection Agency. The linear model is rigid, absolute and wrong. The resulting environmental regulations are having a negative impact, not only on societal costs, but on our health as well.
Holman Jenkins, WSJ - A defective radiation-risk standard holds back our most important low-carbon energy source - nuclear power. What keeps nuclear costs high? The “linear no-threshold” model of radiation risk has become the world’s go-to standard for nuclear safety, source of repeated (and unfulfilled) forecasts of thousands of cancer deaths from Chernobyl or Fukushima. LNT is why nuclear plants shoulder artificially huge costs not to protect against accidents, but to protect against trivial emissions.
