Abstract
Abstract

In this study, we conducted a spectroscopic characterization of natural milky quartz sample from Wadi Araba at the Egyptian Eastern Desert. This quartz material had been studied using scanning electron microscope (SEM), X-ray powder diffraction (XRD), UV–visible spectrophotometer (UV–vis), Fourier transform infrared spectrometer (FTIR), X-ray fluorescence spectrometer (XRF), inductively coupled plasma optical emission spectrometer (ICP-OES) and electron spin resonance (ESR) technique. In the current study, we have used raw samples as-received and gamma-irradiated conditions. The results reviled that gamma radiation had a slight influence on the color of milky quartz samples. XRF and inductively coupled plasma optical emission spectrometer were used to recognition the elemental composition of the raw sample. The ESR spectrum accomplished at room temperature display intrinsic defects such as Aluminium (Al) trap center. Furthermore, with increasing the additive doses the area under the dose response curve increases as a polynomial function, which applicable for ESR dating aspects.
