摘要: Experiences of the Regional Radiation Physics and Protection Service (RRPPS) in performance assessment diagnostic X-ray QA instrumentation on-patient dosemeters are recounted. Issues relating to provision realistic reproducible reference conditions for calibrated X-irradiations considered summary statistics from test measurements dose kVp meters provided. For both it is indicated that as many 25% instruments used routine use U.K. may require some adjustment before they can truly be said performing manufacturer intended. Results intercomparison exercises patient dosimetry services also discussed. It apparent that, those centres participating exercise, assessments generally being obtained within a bias relative standard deviation less then 10%.
