Computer-controlled sampling system for airborne particulates

A self-contained, mobile, computer-controlled air-sampling system has been designed and fabricated that also collects and records the data from eight meteorological sensors. The air-samplers are activated automatically when the collected meteorological data meet the criteria specified at the beginning of the data-collection run. The filters from the samplers are intended to collect airborne 239Pu for later radionuclide analysis and correlation with the meteorological data for the study of resuspended airborne radioactivity and for the development of a predictive model. This paper describes the system hardware, discusses the system and software concepts, and outlines the operational procedures for the system
