The structure of this Code of Practice differs from that of TRS-277 and more closely resembles that of TRS-381 in that the practical recommendations and data for each radiation type have been placed in an individual section devoted to that radiation type. Each essentially forms a different Code of Practice and includes detailed procedures and worksheets. The Code is addressed to users provided with calibrations in terms of absorbed dose to water traceable to a Primary Standard Dosimetry Laboratory. This category of users is likely to become the large majority since most standard laboratories are prepared to, or are planning to, supply calibrations in terms of absorbed dose to water at the reference radiation qualities recommended in this Code of Practice. Users who are not yet provided with calibrations in terms of absorbed dose to water may still refer to the current air kerma based codes of practice, such as TRS-277 and TRS-381, or adopt the present document using a calibration factor in terms of absorbed dose to water derived from an air kerma calibration as described in the text.
