Abstract
A two-year research project has been completed involving the development, and assessment of an atmospheric sampling system based on miniature remotely guided aircraft. The system is designed for short duration sampling of the atmosphere below 1,000 meters for pollutant, toxic, and hazardous materials. The development focused on two sampling methodologies to demonstrate the viability of the system; (a) gamma radiation sampling via digital dosimeters; and (b) gaseous whole-air grab sampling with a miniature pump and tedlar bags for later analysis by gas chromatography. The aircraft design parameters included low aircraft cost; ease of transport in an average automobile; the ability to be operated/flown from relatively restricted areas, to be very inexpensive to operate, have a payload capacity to accommodate a variety of sampling devices capable of producing high quality data, to be resistant to electronic interference, and to be able to linger in an effluent plume, or over some suspect location for periods up to 30 minutes. Application of the system is presently best suited to rapid initial survey work rather than compliance air monitoring.
