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.

A pebble divertor concept is to use the flow of multi layer pebbles as plasma facing component In the divertor plasma, the falling behavior of pebbles is affected by various forces: electromagnetic force, electrostatic force, plasma static pressure and plasma momentum flux. The forces against pebbles in divertor plasma are calculated by referring the edge modeling result of an ITER CDA type divertor. The result of the calculation is that the behavior of pebbles is dominantly affected by the plasma momentum flux. The influence of the electromagnetic force, the electrostatic force and the plasma static pressure can be negligible.
