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.

The magnetic flux evolution problem in toroidal plasmas is formulated in a framework suitable for integrating externally imposed magnetic field components with internal components from bootstrap current and auxiliary current drive. The formulation is applicable to 3-dimensional (3-D) stellarator equilibria, and reduces to 2-D form for axisymmetric plasmas. Here the numerical implementation of this framework is described. Conservative integrations schemes, resolution close to the magnetic axis, and efficient methods for flux surface averaging are discussed. Results from the test code THRIFT (THRee dimensional Inductive Flux evolution in Toroidal plasmas) are used to illustrate numerical convergence properties for a low aspect ratio stellarator and the axisymmetric NSTX spherical torus.
