【摘要】 2012年西北核技术研究所计量测试站组织了一次γ射线空气比释动能量值标准比对,参比实验室7家。根据现有条件,7家计量站选择相应量程的电离室参加比对,参比标准装置7个,获得了20组测量数据。比对结果符合相关技术规范要求,归一化偏差均小于1。比对数据表明所有参比实验室的测量结果与参考值之差都在合理预期之内,比对结果令人满意。更多还原

【Abstract】 The standard comparison for Air Kerma of γ-rays with attendance of seven participants organized by the Metrology and Test station of Northwest Institute of Nuclear Technology in 2012 was introduced. According to existing conditions,each participating laboratory chose the ionization chamber of appropriate range to accomplish the comparison. The experiment data of comparison indicate that the deviations between measurement values and reference values are within the reasonable expectation,the results are considered satisfactory.更多还原
