Fabrication And Characterization Of Normoxic Polymer Gel Dosimeter By Using Raman Spectroscopy At Low X-Ray Energies

Fabrication And Characterization Of Normoxic Polymer Gel Dosimeter By Using Raman Spectroscopy At Low X-Ray Energies

Polymer gel dosimeters are fabricated from radiation sensitive chemicals which, upon irradiation, polymerize as a function of the absorbed radiation dose. Two types of normoxic polymer gel dosimeters were fabricated, which is PHEAG (polyhydroxyethyl acrylate) and PHEMAG (polyhydroxyethyl methacryla...
