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 this paper, operational methods of carbon sheet pump (CSP) which aims at control of hydrogen recycling are investigated. Although the pumping effect of CSP is confirmed in an actual plasma device, the experimental results suggest that a certain amount of gases are adsorbed on CSP under an actual plasma circumstance. The operational methods are contrived and are carried out for the reduction of the adsorbed gases on CSP. Time evolution of total pressures in several regions of the GAMMA 10 vacuum vessel is estimated by numerical analysis in order to evaluate the feasibility of applying CSP to the GAMMA 10 central region. These results suggest that CSP is applicable to actual plasma devices under a suitable operational method.
