Abstract
The aqueous benzoate system, as typified by 6 × 10−4 M calcium benzoate, meets many of the requirements for a sensitive chemical dosimeter. The concentration of salicylic acid, determined spectrophotofluorometrically, increases linearly with radiation dose in the range 5 to 5000 rads and is independent of temperature from 15 to 45 °C, of energy from 160 kev to 3 Mev, and of dose rate from 4 to about 1000 rads/minute. The decrease in sensitivity with increasing dose rate from 1000 to 85,000 rads/minute is reported.
