L X-ray differential cross-sections of uranium were calculated at several polar scattering angles (85°, 95°, 105°, 115°, 125°, and 135°) at 59.54-keV photon energy by using a Si(Li) detector. We observed that Ll and Lα X-rays were dependent on the polar scattering angle, whereas Lβ and Lγ X-rays were independent of the polar scattering angle. Therefore, the anisotropy parameters for Ll and Lα X-rays were obtained using the intensity ratios of Ll to Lγ X-rays and of Lα to Lγ X-rays to reduce some systematic errors.

The energy absorption buildup factors (EABF) have been calculated for some thermoluminescent dosimetric materials (Al2O3 and SiO2) in the energy region 0.015-15MeV up to the penetration depth of 40 mean free paths (mfp). Also, kerma relative to air has been determined for these materials. It is observed that the energy absorption buildup factors and kerma relative to air depend on the photon energy and chemical content. Also, the energy absorption build up factors are found the highest in intermediate energy whereas the lowest in low- as well as high energies.
