Question

6.15. An aluminum ionization chamber containing 10 cm3 air at 20°C and 760 torr operates under Bragg-Gray conditions. After a 1-hour exposure to 6oCo gamma rays, 3.6 x 10-9 C of charge is collected. If the relative mass stopping power of Al for the electrons generated by the 60Co gammas is 0.875, what was the dose to the aluminum?
