在X光探伤系统中使用效率较高的CsI∶Tl晶体作为X光转换体。CsI∶Tl晶体对X光的响应关系是精密图像处理、定量测量所需的一项重要参量,理论上已经推导了CsI∶Tl晶体对X光的响应呈现线性关系,并针对性地设计了在60Co放射源上的定量测量实验,所获数据不仅充分证明了理论推导的正确性,还证明了相应系统的这种线性关系的线性度非常好。
In the X-ray detection system, a more efficient CsI: Tl crystal is used as the X-ray converter. The response of CsI: Tl crystal to X-ray is an important parameter for precision image processing and quantitative measurement. Theoretically, the response of CsI: Tl crystal to X-ray shows a linear relationship, 60Co radioactive source on the quantitative measurement experiments, the data obtained not only fully proved the theoretical derivation of the correctness, but also proved that the linearity of the linear relationship of the corresponding system is very good.
