Risk assessment and risk management implications of hormesis.
International and US radiation protection standards are based upon risk assessment and risk management processes. The assessment of radiation risk is derived from the linear no-threshold (LNT) model. Risk management is based on more subjective value judgements. If the radiation dose-response was found to be hormetic, considerable quantitative data would be needed before current radiation protection standards would change. There would be added complexity, and consideration might have to be given to the additive effects of an individual's exposures to medical radiation and other potential carcinogens.
