From the publication:
Abstract Cancer risk coefficients for ionizing radiation are currently based on the assumption that, after the bombing of Hiroshima and Nagasaki, there were no late effects either of the early selection (survival of the fittest) or the early marrow damage. These negative findings were the result of applying a linear model of relative risk to the deaths of 5 year survivors. By applying a linear-quadratic model to these deaths (i.e. a model with more than one degree of freedom) we have obtained evidence of beneficial effects of selection as well as harmful effects of radiation; also evidence that the harmful effects include marrow damage as well as cancer. Consequently, the present method of risk estimation - by linear extrapolation of high dose effects - is no longer suitable to estimating the cancer risks of occupational exposures or background radiation.
