摘要：

Two new instruments were developed for the U.S. Department of Energy Environmental Science Management Program (EMSP) to perform more detailed exposure assessment measurements at Fernald, OH. Fernald is a former uranium processing facility undergoing remediation. The instruments are a miniature radon and thoron detector, and a miniature particle size spectrum analyzer. Ongoing measurements of both thoron ((220)Rn) and radon ((222)Rn) gas are now being made at four locations: (1) at Fernald; (2) at the New York City National Weather Service site, used as a quality control (QC) site; (3) at a private home in Bangkok used as a QC site; and (4) at a research center and rare earth development facility processing monazite ore near Bangkok. Particle size distribution measurements are presented for two locations: at Fernald and at the Rare Earth Facility near Bangkok. Continuous radon and thoron measurements were made at all sites for at least I year and the bronchial dose is reported. (c) 2004 Published by Elsevier B.V.
