Mass Attenuation Coefficients and Related Parameters of Citrine at Different Gamma Rays Energy using Compton Scattering Technique

Citrine is a transparent gemstone, yellow microcrystalline quartz variety. Natural citrine is very rare and will actually lose its color upon heating to more than 200°C, and the yellow color will occur again when the crystal is irradiated with Xor gamma-rays, indicating that attenuation parameters is important to enhancements by irradiation. In this work, the mass attenuation coefficients of citrine were measured at the different energy of gamma-rays using the Compton scattering technique. The results show that, the experimental values of mass attenuation coefficient are in good agreement with the theoretical values. The mass attenuation coefficients increased with the decreasing of the gamma ray energies. This may be attributed to the higher photon interaction probability of citrine at lower energy. This result is a first report of mass attenuation coefficient of citrine at different gamma ray energies. © 2013 The Authors. Published by Kasem Bundit University.
