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.

The environmental monitoring system for radiation exposure due to light water reactor (LWR) nuclear power plant plume is described. This system, employing a NaI(Tl) scintillation detector with an exposure rate conversion circuit, has the capability of highly accurate evaluation of radiation exposure due to an LWR plume with 0.15 million R/yr (39 nC/kg.yr) overevaluation and 0.05 million R/yr (13 nC/kg.yr) underevaluation. Plume exposure is identified by combining the time variation property of the exposure rate with meteorological parameters. Outlines of the present system are described, including monitoring results obtained over a 98-day period by tentative system at an LWR site boundary.
