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.

An End Plasma System was designed for the MARS tandem mirror reactor. This includes an electrostatic direct converter, a halo plasma scraper, a vacuum pumping system, and a vacuum enclosure. The converter recovers 327 MW of electrical power and absorbs 239 MW of thermal power from the charged particle energy in the plasma fans. The system provides the vacuum pumping necessary to remove the helium ash, accompanying fuel ions, and impurities present in the reactor. It also provides a means to control the central cell plasma potential relative to the first wall.
