The U.S. Million Person Study of Low-Dose-Rate Health Effects
There is a critical knowledge gap regarding the health consequences of exposure to radiation received gradually over time. While there is a plethora of studies on the risks of adverse outcomes from both acute and high-dose exposures, including the landmark study of atomic bomb survivors, these are not characteristic of the chronic exposure to low-dose radiation encountered in occupational and public settings. In addition, smaller cohorts have limited numbers leading to reduced statistical power.

Estimating radiological risks is an essential part of an assessment of fusion as an attractive source of energy. Due to the limited data specific to radionuclides of interest to fusion reactors, one of the goals of this work is to expand the Dose Conversion Factors (DCF) library for use in the calculation of different types of off-site doses and associated health effect consequences. This expansion accounts for about 300 radionuclides included in accidental activity releases from HYLIFE-II and SOMBRERO IFE Power Plants. Furthermore, for each of the radionuclides included in the new DCF library, we address a parametric study of accident consequences by varying the atmospheric stability, wind speed, rain conditions, and thermal plume rise. The results of these calculations allow us to identify the most troublesome radionuclides in terms of safety consequences as well as the impact of the different atmospheric scenarios.
