使用X光电视做透视检查时,每于点片曝光的瞬间,因毫安猛增,使监视器上发出耀眼的光亮。这不仅对工作人员眼睛产生强烈地刺激,而且对增强器、摄象管和显象管也是一次巨大的光电冲击,严重地影响着它们的寿命。因此,在工作中对它们保护是完全必要的。摄象管、显象管的保护常识,已见于有关工业电视和广播电视书刊,而对增强器的保护尚未见有提及。在X线电视中,只要对增强器进行了保护,也就间接地保护
When using the X-ray TV for fluoroscopy, every time a spot is exposed, the monitor emits bright light due to the rapid increase of the millimeter. This not only strongly stimulates the eyes of workers, but also a huge photoelectric impact on booster, video tube and kinescope, seriously affecting their life. Therefore, it is absolutely necessary to protect them at work. The general knowledge of the protection of the video tube and the picture tube has been found in the books on industrial television and radio and television, and no mention has been made of the protection of the enhancer. In X-ray television, as long as the enhancer has been protected, it is indirectly protected
