一、引言γ射线空气比释动能标准装置的建立是电离辐射量值改制的一个重要步骤,同时作为γ射线空气比释动能计量器具检定系统表框图(2011年3月6日起实施)中的关键一环,对量值溯源起着不可替代的作用。我院新建立的γ射线空气比释动能标准装置已通过国家计量院的验收,并通过相应检定(校准)项目的计量标准考核,可进行治疗水平剂量计、辐射防护和环境仪表等工作计量器具的量值传递,为γ射线在放射治
I. INTRODUCTION The establishment of a gamma-ray air kerma-standard device is an important step in the restructuring of ionizing radiation. In the meantime, as a gamma-ray air-kerosene meter calibration system block diagram (implemented on March 6, 2011) The key link plays an irreplaceable role in the traceability of the quantity. Our newly established γ-ray air kerma standard device has passed the acceptance test of the National Metrology Institute and has passed the assessment of the measurement standards of the corresponding verification (calibration) project for the treatment of dosimeters, radiation protection and environmental instrumentation work measuring instruments The magnitude of the transfer, for gamma rays in radiology
