This research empirically determined the plutonium-239 airborne concentration alpha correction factor for an ADM-300 zinc sulfide detection system via ambient radon-222 progeny air sampling using a RADeCOORTM high volume air sampler. Radon progeny air samples were collected on a four inch glass fiber filter and evaluated on both a high purity germanium detector and the ADM-300 simultaneously using the three count method. These data were analyzed to obtain a loss fraction in the glass fiber filter for the bismuth-214 collected. The bismuth-214 response then was used to estimate a loss fraction for plutonium-239. The plutonium-239 airborne concentration alpha correction factor for the ADM-300 detection system was found to be 239 +/- 22 dpm-ft3cpm-m3 as compared to the theoretical correction factor of 500 dpm-ft3cpm-m3 .
