There are 3.4 x 105 photons with 250 keV energy interacting inside an air-filled ionization chamber (by photon electric effect) in each hour.
(1) In each hour, how many ion pairs will be produced? Suppose the W-value for the photon in the air is 34 eV/i.p.
(2)What is the total charge in one sign that will be generated in an hour?
(3) What is the mass of air in the ionization chamber? Suppose the volume is 0.1 L
(4) What is the exposure rate of this X-ray?
