本文研究了低温对低通量密度中子照像速度的影响,得出了低温照像的最佳温度值;给出了NNU-4闪烁增强屏—天津X-Ⅲ胶片显示、记录系统在常温和低温下的黑度—辐照量特性曲线。
In this paper, the effect of low temperature on the imaging speed of low-flux density neutron has been studied, and the optimum temperature of low-flux density neutron has been obtained. The NNU-4 scintillation enhancement screen-Tianjin X-Ⅲ film shows that the recording system operates at room temperature And darkness at low temperature - radiation characteristic curve.
