15、r Calibration of Germanium Detec- tors for In-Situ Gamma-Ray Measurements.) This standard is the responsibility of the Accredited American Standards Committee on Radiation Instru- mentation, N42. Committee N42 delegated the development of this standard to Subcommittee N42.RM. Drafts were reviewed by
16、 Committee N42, Subcommittee N42.RM, and other interested parties; and the comments were utilized in producing the standard as finally approved. This standard was approved on N42 letter ballot of 25 September 2002. Participants At the time Committee N42 approved this standard, it had the following m

CAUTIONWhile guidance on the application of in-situ gamma-ray spectrometry and the use of in-situ measurement data is beyond the scope of this st
21、andard, some general remarks concerning the technique are warranted. As with any measurement technique, one must be aware of assumptions that give rise to limitations on the range of potential applica- tions. In-situ measurements carry specific assumption regarding many measurement parameters. The m
22、ost notable parameter is the distribution of activity in the source. A detector measures only the gamma-ray fluence from which one can infer an activity concentration. The extent to which the measurement assumptions reflect the actual or true measure- ment conditions is the extent to which the measu
23、rements results will satisfy their intended purpose. For example, a detector that is calibrated to measure sources with uniformly distributed activity will produce inconsistent and mislead- ing results if the source is highly heterogeneous. However, there could be an acceptable degree of heterogenei
24、ty that would still allow for useful data. Service providers and their customers should consider using data quality objectives as a guide or a means to evaluate a measurement program that uses or intends to use this technique. 2.
