【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。更多还原

【Abstract】 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.更多还原
