LIU Weixia (YangquanCityComprehensive Inspectionand TestingCenter)

Abstract:Measurement comparison is an important means to supervise the measurement abilityof alaboratory.In this paper,the average glandular dose (AGD)of the medical breast X-ray radiation source is compared and verified. The technical background of the measurement comparison is analyzed,the uncertaintyof the measurement results is evaluated,andtheevaluationmethodofthecomparisonresultsisintroduced.Finalysatisfactoryresultsarebained to ensure theunity,accuracyand reliabilityof the verifcationresults of the medical breast X-rayradiation source.
