Abstract A mobile breath radon detection apparatus has been used for measuring low radium 226 body burdens. The unique feature of the apparatus is an acclimation room designed to accommodate subjects for periods up to 1 week in a low-radon environment. Radon concentrations in the acclimation room have been reduced to an operating level of 0.0005 pCi per liter, a reduction of approximately 600:1, by an air processing unit employing activated coconut charcoal. This apparatus permits determination of very low radium 226 body burdens in comfortable surroundings for two subjects simultaneously, during the extended periods required for elimination of previously inhaled radon from the body. The construction and operation of the acclimation room and breath sample collection are described. Radium 226 body burdens for the subjects and a radon elimination curve for one subject are included.
