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 back Faraday shield is proposed for improving a cooling design of Faraday shield and better antenna-plasma coupling of a fast wave antenna. The radiofrequency properties of an antenna with the back Faraday shield have been investigated in the JFT-2M tokamak. The loading resistance of the antenna was significantly higher than that of an antenna using a conventional Faraday shield. The back Faraday shield antenna did not show adverse results for launching fast waves up to 550 kW of coupled power. The electron heating was observed by a soft X ray spectrum measurement increased by 0.35 keV during 250 kW of fast wave application.
