| Summary, etc. | The first part of this thesis aims to develop and optimize the formulation of a radiation-sensitive material of silver nitrate in gelatin, a capping agent, to prepare radiochromic gel dosimeters suitable for dosimetry applications up to 100 Gy. Gamma radiation-induced Ag nanoparticles (NPs) formation in silver nitrate gel dosimeter at different silver nitrate concentration, gelatin %, isopropanol % and pH was investigated. The absorption spectrum of the Þ-irradiated gel dosimeter exhibited a Surface Plasmon Resonance band (SPR) at a wavelength of 450 nm nm indicating AgNPs formation upon Þ-irradiation.The intensity of this peak grows linearly with increasing absorbed doses up to 100 Gy. The sensitivity of radiation increases with the increase of Ag⁺ ion concentrations and the decrease of gelatin content. In addition, using isopropanol enhanced the development of AgNPs in the gel dosimeter. The increase of isopropanol in the gel (100 mM The first part of this thesis aims to develop and optimize the formulation of a radiation-sensitive material of silver nitrate in gelatin, a capping agent, to prepare radiochromic gel dosimeters suitable for dosimetry applications up to 100 Gy.

The sensitivity of radiation increases with the increase of Ag+ ion concentrations and the decrease of gelatin content. In addition, using isopropanol enhanced the development of AgNPs in the gel dosimeter. The increase of isopropanol in the gel (100 mM Ag+) from 0 to 20% enhanced the radiation sensitivity by 16.75% |
