| Résumé: | Radiation-induced polymerization of acrylamide and methacrylamide-based
polymer gel dosimeters potentially used for the verification of complex dose
distributions in 3D associated with conformal radiotherapy has been studied
using nuclear magnetic resonance (NMR), Raman spectroscopy and
impedance analyzer methods at room temperature. Three polymer gels of
polyacrylamide (PAAmG), polymethacrylamide (PMAAmG) and
poly(acrylamide-co-methacrylamide) (PAAm-co-MAAmG) were synthesized
in oxygen free condition from acrylamide (AAm) and methacrylamide
(MAAm) as monomers and N, N'-methylene-bis-acrylamide (BIS) as Crosslinker
at various concentration from 2% to 6% and 6% gelatin. The
comonomers (AAm, MAAm and BIS) were dissolved in an aqueous gelatin |
