介绍了一种用2K× 2K CMOS图像传感器（CIS）成像系统测量60 Co γ射线环境剂量率的仪器和方法。实验是在60 Co γ射线装置上进行的。利用CIS成像系统测量了不同剂量率γ射线环境下输出信号的增加量、有效尖峰频率。PTW-UNIDOS还测量了剂量率。此外，还分析了平均输出信号增量、有效尖峰频率与剂量率的关系，并用于测量剂量率。我们的测量系统测量的剂量率与PTW-UNIDOS的结果符合得很好。通常，使用有效尖峰的频率来测量剂量率会更有效，但它也更复杂。文中还讨论了CIS成像系统的测量范围和寿命。该工作为测量60 Co γ射线环境中的剂量率提供了一种很好的方法。
The Instrument and method for measuring the dose rates in 60 Co γ rays environment with a 2K× 2K CMOS image sensor (CIS) imaging system are presented. The experiments were carried out at 60 Co γ rays facility. The output signal increase, the frequency of effective spike were measured by the CIS imaging system under the γ rays environment at various dose rates. The dose rates were also measured by the PTW-UNIDOS. Besides, the relationship between mean output signal increase, frequency of effective spike, and dose rates are analyzed and used to measure the dose rates. The dose rates measured by our measurement system are in good agreement with the PTW-UNIDOS results. Usually, using the frequency of effective spikes to measure the dose rates would be more efficient but it is also more complex. The measuring ranges, the life span of the CIS imaging system are also discussed. This work can provide a great way to measure dose rates in 60 Co γ rays environment.
