【摘要】 实验研究了硫酸亚铁-苯甲酸-二甲酚橙化学剂量计体系的基本性质。测定该体系的 G(Fe³⁺)是61.2±0.6。发现当 Fe³⁺浓度增大时,峰红移。如果不管峰移,而只取最高峰的光密度值,那么光密度值与吸收剂量之间的线性关系上限可达4000rad。更多还原

【Abstract】 The basic properties of FBX system have been studied.TheG-Value(Fe)determined is 61.2±0.6.The red shift of the position of theabsorption peak was found when the concentration of ferric increase.If theoptical density at the absorption peak was always taken,the linear relationbetween the optical density and the absorbed dose was got up to 4000 rads.更多还原
