Abstract

See full text

New compositions of tissue-equivalent three-dimensional polymer gel dosimeters based on acrylamide (AAm), N-isopropylacrylamide (NIPAM), N-(Hydroxymethyl)acrylamide (NHMA), diacetone acrylamide (DAAM) and N-Vinylcaprolactam (NVCL) monomer with ethylene glycol co-solvent have been introduced in this invention for radiotherapy dosimetry. The dosimeter was irradiated with 6 and 15 MV linear accelerator at absorbed doses up to 10 Gy. The nuclear magnetic resonance (NMR) spin-spin relaxation rate (R2) for water proton surrounding polymer formation was used to investigate the degree of polymerization of the five gels. The effect of additives, dose rate, radiation energy, stability of the polymerization after irradiation, were investigated on the dose response of the gels.
