Construction and evaluation of an airshed-episode model for air resource management

Creator:: Reiquam, Howard Edward, 1931-
Abstract:: A mathematical model of the atmosphere in an airshed is developed, which relates pollutant source distributions and intensities to the volume of air available for dispersion and to pollutant concentrations or air quality standards. It can be used as a tool for obtaining an answer to an air resource management...

The design and construction of an ionization chamber to measure background radiation

Creator:: Weaver, Kenneth Earl
Abstract:: An ionization chamber was constructed, using a fiberglass wall sphere, for the purpose of measuring background radiation. The system consists of the fiberglass wall chamber, 38.85 liters in volume, air filled, not sealed, used in conjunction with a precision capacitor, nulling voltage supply and electrometer. It was calibrated against a...
