The parallelism before existing air kerma formalisms based on the 'absorbed dose to air' chamber factor, N D (or N gas ), and the more simple approach based on calibrations in terms of absorbed dose to water, N w , is described. The importance of avoiding steps performed by the user that introduce avoidable uncertainties in the dosimetric procedure, is emphasized. Radiation beam quality factors normalized to 60 Co gamma -rays have been calculated from a comparison between the two formalisms, and sets of tables produced for the different ionization chambers included in the 1987 IAEA Code of Practice. The calculated set of data is compared with existing experimental determinations at Primary Standard Dosimetry Laboratories, showing agreement within estimated uncertainties.
