Certification of Standardized Radioactive Sources-BF5A12D9

This Report presents the Commission's recommendations on the information that should be provided when a standardized radioactive source is issued. In ICRU Report 10c, issued in 1963, the Commission treated international comparisons of source standards and discussed the factors which affect the reliability of a source as a standard, i.e., radionuclidic purity, half life, decay scheme and chemical purity and stability. Similar desiderata apply to any source issued as a standard but considerable variability exists in the amount and kind of data provided by the suppliers of standardized sources. Thus, agreement as to the contents required in any certificate, specifying a standard source is highly desirable. Report 12 is intended to meet this need. The report treats the problems of certification of standardized radioactive sources, clarifies the pertinent terms previously defined by the ICRU and gives a comprehensive list of the information which should be provided with a standardized source. The report is intended primarily as a guide for suppliers of standardized sources, but should also be helpful to users of such sources.
