摘　　要：介绍了通过采取增加曝光时间等措施,实现了使用低能X射线机代替γ射线机透照厚壁容器的事例,通过事例说明:超过X射线机说明书标称最大透照厚度的工件,在一定范围内,采取相应措施后,也能完成透照,特别是在透照数量不大且时间紧迫、透照设备受限的情况下,用来透照既省时又经济。This article describes the increase in exposure time by taking other measures to achieve a low-energy X-ray machine instead of using γ-ray machine through the thick-walled container according to the examples. Through this example shows： X-ray machine instructions than the maximum nominal thickness of the work piece through the photos, within a certain range, to take corresponding measures can be completed through the photos, especially in the small number of trans illumination and time is pressing, according to the device through limited circumstances, for trans illumination is both time and economy.
