Radiation risk is linear with dose at low doses

Abstract

This paper presents a brief argument, based on a mechanistic approach, to show that radiation risk is linear with radiation dose from zero dose up. Similarities in cellular effects lead to the assumption of a common mechanism and the DNA double strand break is identified as the crucial radiation-induced lesion. A cancer model extends the cellular effects to the main radiation risk providing confirmation of the dose effect for cancer at low doses.
