Sensitivity of HEMATEG Induced by Radiation Dose in the Diagnostic X-Ray Energy Range

Abstract:

The aim of this study is to determine sensitivity of new recipes polymer gel HEMATEG with varied x-ray exposure by using UV-visible spectrophotometer as an evaluation technique. The gels were irradiated by x-ray radiation and the polymerization of HEMATEG were followed. Polymerization was read based on absorption spectra in the range wavelength UV 300 nm to 700 nm. The dependency of polymerization with increasing of exposure dose was determined by changes in the band gap energy (E_g) and Urbach energy (∆E). In the UV-visible region, E_g with indirect transition of HEMATEG were decreased with increasing radiation dose while, ∆E were increased with increasing radiation dose. This observation supported the increase of structured disorder of the polymer with increasing radiation dose. This study proved that HEMATEG had a high potential to be used as a 3-dimensional dosimeter in the diagnostic x-ray.
