Abstract
This study examines several important features of characteristic X-rays, including their production, spectroscopy and interactions with materials. Characteristic X-rays for different elements (29Cu, 42Mo, 47Ag, 56Ba and 65Tb) were obtained from a variable energy X-ray source by using gamma rays around 60 keV from 241Am. It was found that the energy and intensity of generated characteristic X-ray photons are proportional to the atomic number of the targets within the variable energy X-ray source. In addition, X-ray spectroscopy for such targets was investigated by using two gas- filled (54 Xe and 36Kr) proportional counters. Furthermore, it was discovered that the probability of photoelectric absorption of (54 Xe) gas-filled proportional counter is almost 1.5 times higher than the probability of photoelectric absorption of (36 Kr) gas-filled proportional counter.
