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 experiment of Alfvén wave excitation and heating of a field-reversed configuration (FRC) plasma is presented. A low frequency magnetic pulse is applied to the FRC plasma by an azimuthally symmetrical antenna. After the pulse applied, an obvious increase of the plasma energy and the propagation of the magnetic wave are simultaneously observed. The excited wave propagates along the steady magnetic field line with the radially distributed phase velocity. The phase velocity outside the separatrix agrees the dispersion relation of the shear Alfvén wave. On the other hand, it is close to the acoustic speed, inside the separatrix. It is also observed that there is a generation of a non-oscillating toroidal magnetic field, which is possible to cause the heating of the FRC plasma.
