The optical absorption spectra, dosimetric wavelengths, energy and dose dependent response, sensitivity and lower detection limits were evaluated and compared for both clinical beams. All results obtained in this study are satisfactory and indicate the viability of implementing this dosimeter in photon and electron 3D dosimetry.openAccesschemical dosemeterschemical dosemetersgelsspectrophotometryphotonsbeamselectron beamscomparative evaluationsTexto completo de eventohttps://orcid.org/0000-0001-7137-0613
