Radiation carcinogenesis at low doses.
In: Science, Vol. 175, Nr. 4018: S. 200-202
An analysis of experimental findings indicates that the induction of a manmmary neoplasm in the Sprague-Dawley rat is dependent on the action of radiation on more than one cell. Although a linear relation between incidence and x-ray dose might be consistent with available data, such a relation would be fortuitous and linear extrapolation to lower doses is unjustified.
