Biological Effects From Low Doses and Dose Rates of Ionizing Radiation: Science in the Service of Protecting Humans, a Synopsis

Abstract

There is considerable controversy regarding risk of health detriment after low-level exposure to ionizing radiation. This stems in part from a sort of distance between radiation biologists, epidemiologists, and radiation protection professionals, as well as regulatory institutions. Also, there is a lack of overview of the relevant data and their origins regarding health risks at low doses of ionizing radiation. This feeds seriously into a somewhat hazy fear of ionizing radiation that besets large portions of the public. The current synopsis aims at presenting a holistic view in a concise yet comprehensive manner in order to help people understand the full extent of inputs into attempting to relate low-dose radiation exposure to health risk. It emerges again that different approaches must be found for optimal radiation protection replacing the use of the linear no-threshold (LNT) model.
