The conventions adopted for measuring the exposure dose of high energy radiation with cavity ionization chambers are reviewed and related problems are discussed. Theoretical and experimental evidence is presented to suggest that the exposure dose is measured at the geometric centre of the air volume and that corrections are necessary for absorption of the radiation in the entire thickness of the equilibrium wall and for non-uniformity of the radiation across the chamber.
