摘要
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。
The effect of low temperature on imaging speed of films for low flux neutron radiography has been studied experimentally. The optimum temperature for the neutron radiography is given. Darkness as a function of exposure is presented for the detecting and recording system, NNU-4 scintillator intensifying screen and Tianjin X-Ⅲ film at low and room temperatures respectively.
