A thin-walled air ionization chamber whose volume is 0.5cm^3 collects a charge of 1.65 x 10^ -9 C when placed into a plastic phantom whose relative mass stopping power is 1.1. When manufactured, the ionization chamber was sealed when the temperature was 25 degrees C and the atmospheric pressure was 770 mm Hg. What was the absorbed dose, in Gy and in rads, at the point of measurement?
