Gamma ray characterization of the albedo of atmospheric dust from Southeast Anatolia, Turkey
Atmospheric dust samples were collected using PM10 (particulate matter less than 10 mu m) and PM2.5 (particulate matter less than 2.5 mu m) filters in 2019 from Southeast Anatolia, Turkey. The direction and source of the dust were determined using the Moderate Resolution Imaging Spectroradiometer (MODIS) satellite view and Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model. X-ray diffraction (XRD) has shown the presence of calcite and quartz as major components of the aerosol dust. The albedo parameters of atmospheric dust were experimentally determined for 59.54 keV photons emitted from an Am-241 source. Compton and coherent scattered peaks were acquired with a high purity germanium detector. The sample collected in May has a higher density than in June. The sample density at PM10 is larger than PM2.5 and the density of 23 June 2019 is smaller than for the other dates. The albedo parameters of the filter in June and May for PM10 are greater than those of PM2.5. The dust of larger particles is more reflected by the high-energy photons.
