Abstract

The purpose of this study was to determine the optimal wavelength for a polymer-gel dosimeter previously developed by our research groups; this was done through a spectrophotometric characterization of its dosimetric properties. A gel sample was irradiated with a 6-MV photon beam from a linear accelerator, and its response was spectrophotometrically analyzed. The absorbance, dose linearity, reproducibility, and dose-rate dependence of the dosimeter were evaluated at various wavelengths and doses. The absorbance of the polymer-gel dosimeter did not show any peak sensitivity within the studied range of wavelengths. For the range of doses studied, the best dose linearity was recorded, with an R2 of 0.9701 at a wavelength of 400 nm. The reproducibility of the results was excellent, and the error in the dose-rate dependence was within the range of ± 3%. The gel dosimeter displayed a very stable response, thus confirming the efficiency of this 3D dosimeter.
