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.
