Method and device for measuring short pulse ionizing radiation

The present invention discloses a method and a device for measuring short pulse ionizing radiation. The method comprises the following steps: pulsed X-ray is controlled to irradiate a diamond detectorto generate electron hole pairs in order to generate electric current; the electric current is controlled to enter a pre-integrated circuit, and an electrical signal is pre-integrated and measured through a current measuring circuit; the measured electrical signal is collected and converted by a data acquisition circuit, and the ionizing radiation dose of a short pulse radiation field therein isobtained. By using the method, the ionizing radiation of the short pulse radiation field can be measured in real time, thereby operation risk is reduced and health of operators is ensured. 本发明公开了一种短脉冲电离辐射测量方法及装置，其中，方法包括以下步骤：控制脉冲X射线照射在金刚石探测器上，生成电子空穴对，以产生电流；控制电流进入预积分电路，对电信号进行预积分，并通过电流测量电路对电信号进行测量；通过数据采集电路对测量的电信号进行采集与转换，获得所在短脉冲辐射场的电离辐射剂量。该方法能够对短脉冲辐射场的电离辐射实现实时测量，从而降低作业危险，保证操作人员的身体健康。
