Determination of Stable Elements in Air Pollution Particulates by Neutron Activation Analysis.
Abstract
Neutron activation analysis was used to determine the quantities of 13 elements in samples of atmospheric particulate matter. Quantities ranged from 0.35 micrograms of Se to 34 milligrams of Ca, which were 0.0002% to 15% of the samples by weight. Twelve other elements were identified, but not quantified. An 80-cu cm lithium-drifted germanium detector with a resolution of 2.2 keV (FWHM) at 1.33 MeV and a 4096-channel analyzer were used for detection and counting of gamma radiation. Data were analyzed by SAMPO, a CDC 6600 computer program; details on the use of SAMPO are included. Techniques and methods of sample collection, sample preparation in quartz and polyethylene ampoules, and data reduction are reported. (Modified author abstract)
