Excerpt
Introduction: The purpose of this paper is to illustrate some of the statistical difficulties of estimating cancer risks from low doses of a carcinogen, that is, from dose levels producing excess risks that are small relative to normal risk. The illustration is by examples from radiation carcinogenesis. More is known about dose-response relationships for ionizing radiation than for any other environmental carcinogen, and models commonly used in curve fitting have widely accepted radiobiological interpretations. Nevertheless, estimates of cancer risk from low doses of ionizing radiation tend to be extremely controversial; disagreements by factors of 100 or more are common.
