This research empirically determined the ²³⁹Pu airborne concentration alpha correction factor for an ADM-300 zinc sulfide detection system via ambient ²²²Rn progeny air sampling using a RADeCO 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 ADMē-300 simultaneously using the three count method. These data were analyzed to obtain a loss fraction in the glass fiber filter for the ²¹⁴Bi collected. The ²¹⁴Bi response then was used to estimate a loss fraction for ²³⁹Pu. The ²³⁹Pu airborne concentration alpha correction factor for the ADM-300 detection system was found to be 445 ± 47 dpm ft³ cpm⁻¹ m⁻³ as compared to a previously published correction factor of 500 dpm ft³ cpm⁻¹ m⁻³.

The article discusses a research study which determined 239plutonim (Pu) airborne concentration alpha correction factor for detecting ADM-300 zinc sulfide through ambient 222 radon (Rn) progeny air sampling. Analysis of data was done to determine the loss fraction for the 214bismuth (Bi) collected from the glass filter fiber. A discussion on the research findings is detailed.
