【摘要】 通过将曲线拟合扩展量程范围的技术应用于传统的电离室探测器,使电离室在低剂量率时工作在饱和收集区,高剂量率时工作在不饱和收集区,从而扩张电离室的量程范围。使得只采用一个电离室便可覆盖8个数量级的剂量率范围,从而实现对现有电离室测量方法补充和发展的目的。更多还原

【Abstract】 It introduces the curve fitting method which allowed ionization chamber detector working with unsaturated amassing current under high dose rate.The method can extend the measuring range,and it may be a supplement of the measurement in using ionization chamber.更多还原
