Notes:
A chemical dosimeter has been developed based on the gas evolution of polymers by γ radiation. The polymers used in this dosimetry were polyacrylamide, poly(vinyl alcohol), and polystyrene. The irradiating γ source was a 60Co annular cell calibrated with the Fricke dosimeter, an average dose rate being 630 rad/min. The irradiated samples were aqueous solution, i.e., polyacrylamide oxygen saturated in water, poly(vinyl alcohol) aerated in water, and polystyrene oxygen saturated in carbon tetrachloride. A manometer system was used as the gas-measuring device. It was found that the dosimeter showed good linearity above 1 Mrad.
