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.

We study flute mode stability of a quadrupole-anchored tandem mirror plasma. The present analysis is based on a Newcomb's Lagrangian density with the assumption of small Larmor radius of the ion in the paraxial approximation. A radial eigenmode equation for flute perturbations is derived without the eikonal approximation in the flux coordinates, where the effects of E×B plasma rotation due to an ambipolar electric field are taken into account. The obtained eigenmode equation is applicable to a mode with arbitrary azimuthal mode number, and can describe interchange modes, E×B rotational modes and also Kelvin -Helmholtz modes driven by the shear effect of E×B plasma rotation.
