| Abstract |
This report discusses the evaluation of selected air filters for their suitability as collection media for the radiological analyses of airborne particulate matter. Standard four-inch diameter filters were analyzed for their natural radioactivity contents. Of the filters tested, glass fiber filters had the highest radium-226 content (0.35 picocuries per filter) and Microsorban filters contained roughly one-third of this activity. Microsorban filters also have lower uranium and thorium contents than do the glass fiber filters. For the analytical methods used in this study, all filter types tested had undetectable polonium-210, lead-210, and radium-228 contents. Dust loading characteristics of selected filters were also evaluated. The results indicate that Microsorban filters have higher collection and dust retention efficiencies (ranging from 6 to 26 percent greater) than do glass fiber filters. As a result of these evaluations, Microsorban filters are being used in the routine environmental radiological air quality monitoring networks operated by the Office of Radiation Programs - Las Vegas Facility (ORP-LVF). |
