Health Physics Society Journal

On the cover: A performance test subjected solid-state dosimeters to laboratory irradiations at the National Insitute of Standards and Technology and to 90 days of simulated field conditions in an environmental chamber at Brookhaven National Laboratory. Here a scientist from the DOE's Environmental Measurements Laboratory measures illuminance on dosimeters in the chamber. See article by Klemic et al. on page 370.
