【摘要】 空气比释动能和照射量都可以用于校准剂量计 ,但仔细研究空气比释动能和照射量基准的原理、定义、建立以及校准和转换为水吸收剂量的计算 ,表明无论从理论上还是实践上空气比释动能都比照射量更为方便 ,而且可能引入的不确定度更小 ,因而更优越。更多还原

【Abstract】 As Air Kerma has been commonly used in radiotherapy, radioprotection, and other fields in calibration dosemeters, the use of unit Exposure had been evidently reduced. Air Kerma has some advantages and convenient in usage comparable to Exposure both theoretically and practically. Consider about the possible uncertainties in establish primary standard and convert to absorbed dose to water in a suitable phantom shows start from Air Kerma primary standard is smaller then that of Exposure.更多还原
