Implications of Recent Epidemiologic Studies for the Linear-Nonthreshold Model and Radiation Protection

NCRP Commentary No. 27 provides a critical review of 29 high-quality epidemiologic studies of populations exposed to radiation in the low dose and low dose-rate range, mostly published within the last 10 years. The Commentary concludes that these recent epidemiologic studies support the continued use of the linear-nonthreshold (LNT) dose-response model to develop practical and prudent guidance on ways to protect workers and the public from the potential for harmful effects of ionizing radiation, specifically, from low linear-energy transfer radiation.
