Abstract
A radiography apparatus in which gas is directly or indirectly ionized by ionizing radiation to form on an insulating film an electrostatic latent image of a body to be examined is provided with at least two gas chambers. In one of the chambers, an anode and a cathode are disposed in opposed relationship, and gas at a predetermined pressure fills the space between the two electrodes. The insulating film is disposed on the surface of one of the electrodes. The film with an electrostatic image formed thereon is moved through the other gas chamber. This chamber is filled with such gas as dry air, the pressure of which gas is substantially in equilibrium relationship with the pressure of the ionizing gas.
