متن کاملPerspective on the use of LNT for radiation protection and risk assessment by the U.S. Environmental Protection Agency.
The U.S. Environmental Protection Agency (EPA) bases its risk assessments, regulatory limits, and nonregulatory guidelines for population exposures to low level ionizing radiation on the linear no-threshold (LNT) hypothesis, which assumes that the risk of cancer due to a low dose exposure is proportional to dose, with no threshold. The use of LNT for radiation protection purposes has been repea...
متن کاملEnvironmental Risk Assessment
