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.

Energetic particle effects on MHD stability of a tandem mirror plasma is studied theoretically. An algebraic dispersion equation with respect to eigenfrequency is derived from a radial eigenmode equation for flute-mode perturbations with an appropriate boundary condition, in which the effects of energetically drifting ions are taken into account. The dispersion equation describes interactions between curvature-driven interchange modes and drift modes driven by energetically drifting ions. In the absence of wave-particle interactions for energetically drifting ions, the dispersion equation is solved numerically, and a stable region formed due to the charge uncovering effects of energetically drifting ions is shown in a parameter space related with the number density and magnetic drift frequency of energetically drifting ions.
