我们经过多次研究,初步试制成功用铁套管加铅胶皮制成携带式防护屏风,初步解决了小型X光机的防护问题,现介绍如下: 具体作法采用粗管直径2.5公分,长71公分两根。细管直径2.0公分,长100公分两根,上头钻1.3公分孔,下头离20公分处向上每隔10公分钻一个孔,共钻四个孔。可随意采用高低(根据机头移动高度选择钻孔),另用两条横棍粗1 After many studies, we initially made a trial production of a portable protective screen made of iron casing and lead rubber, and initially solved the protection problems of small X-ray machines. The detailed introduction is as follows: The concrete method adopts a thick pipe diameter of 2.5 cm and a length of 71 cm Two. Thin tube diameter of 2.0 cm, 100 cm long two, 1.3 cm hole drilling head, head down from 20 cm at 10 cm per hole drill a total of four holes drilled. Feel free to use high and low (according to the choice of mobile height head drilling), the other two with a rough bar 1
