Abstract
New values of the factors required to convert the reading of an ionization chamber calibrated in terms of air kerma (or exposure) to absorbed dose to water for medium energy X-rays were given in a Code of Practice published by the IAEA in 1987. These factors differ by a maximum of 12.5% at 0.15 mm Cu HVL from those given in ICRU Report 23. This paper discusses the difference between the ICRU and IAEA conversion factors and forms the basis of the recommendation of the IPSM low and medium energy X-ray dosimetry working party, that dosimetry in the U.K. should continue to be based on ICRU Report 23 and therefore on the current HPA Code of Practice.
