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.

Detailed stracture of the magnetic field in the Large Helical Deveice (LHD) is studied numerically. The connection length of the divertor field line is found to be the order of several km or more. The possibility of the mirror-confined plasma in the chaotic field line region is shown. The divertor plasma model is proposed based on the long connection length and the existence of the mirror-confined plasma in the chaotic field line region. A new ICRF heating scheme (runaway ion heating scheme) for LHD is also proposed based on the existence of the mirror-confined plasma in the core plasma region.
