AbstractThe Canadian and U.S. standard free-air ionization chambers have been compared under identical conditions of X-ray tube kilovoltage and filtration. The comparison shows that the ratio of exposure dose-rate measurements differs from unity by about 0·3 per cent over the range of X-ray energies for which these chambers are usually used. The observed difference in exposure dose-rate measurements is well within the error limit estimated by the International Commission on Radiological Units and Measurements (1956).
