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.

Several aspects of the numerical solution methods in RETRAN were investigated with the objective of improving or removing time-step size limitations. The investigations focused on the material transport Courant limit associated with the mixture energy equation. The initial development efforts are limited to the homogeneous equilibrium mixture model of two-phase flow. Some of the results are applicable to four- and five-equation two-phase flow models. The solution method improvements were developed and demonstrated by calculations with RETRAN.
