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.

In the GAMMA10 tandem mirror, ion cyclotron range of frequency (ICRF) waves are effectively used for the plasma production and heating. Alfvén ion cyclotron (AIC) modes are spontaneously excited due to the strong heating. Stability boundary for the AIC modes is analyzed by introducing the effective mirror ratio. It is shown that the AIC modes become more unstable with smaller mirror ratio. The pitch angle scattering of the high energy ions due to the AIC mode are clearly observed.
