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.

As severity of accidents increases in beyond-design basis events (B-DBEs) conditions, ambiguity of situations increases among operators and interactions between plant systems/components and operators become more complicated. Three issues were recognized and a framework composed of three corresponding methods was introduced to address the issues on applying Human Factors Engineering (HFE) review for B-DBE conditions. The enhancing framework was applied to a scenario, Total loss of Feed Water with Misleading Indicator, as a trial. The result of the trial showed that the enhancing framework could be applied as far as task analysis was feasible for B-DBE conditions with relevant human reliability analysis method.
