Neutron Activation Technique Used For Measurement Of Aerosol Deposition On Fiber-type Scavengers

Abstract

A feasibility study of the neutron activation technique to measure the amount of deposited titanium oxide aerosol (with median diameters of about 0.7 μm) on fibers is presented. A laboratory setup consisting of an aerosol generator and a wind tunnel—in which the grid-type fiber "scavengers" were exposed to an aerosol flow of 1.0 m/s—allowed a determination of the time dependence of the fiber collection efficiency. The data, normalized for aerosol concentration and size distribution, reveal that the collection efficiency of polyester fiber "scavengers" of the fiber mean diameter of 250 μm reached a maximum (between 3% and 4%) after 5 min of exposure and subsequently dropped to 0.5% after 15 min. © 1990 Elsevier Science Publishing Co., Inc.
