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 rapid decay of magnetic flux during a plasma disruption induces voltages, currents, and Lorentz loadings in nearby electrically-conducting material. Present designs employ toroidal shells or shell segments near the plasma. These shells are divided into sectors for assembly and maintenance considerations, but may have toroidally-continuous conducting paths due to the need for vacuum boundaries. Voltages induced across sector gaps may initiate arcing and subsequent material damage. In addition, induced eddy currents in the shells can interact with the toroidal field and generate large net torques on a sector. A finite element model was used to estimate the induced sector gap voltages and net overturning moments following a 10 ms disruption. The number of shells, toroidal continuity, resistivity, and shell thicknesses were varied. Results are presented that show the effects of these changes on the sector gap voltages and induced loads.
