The present invention provides a unit which linearly matches a function of shielding radiation, which may be externally discharged, directly to an upper part of a pipe for maximizing efficiency when a non-destructive test for checking a coupling part (a welded part and the like) within the pipe (a gas pipe, an oil pipeline, etc.) is performed, whereas it provides a new linear shielding unit which is very useful in terms of safety and convenience as well as makes an easy, simple, rapid and collective action possible as compared with a conventional unit. In other words, the present invention provides a radioactivity shielding unit (100), preferentially realizing radiation shielding rather than a basic welding house as it is lifted directly to the upper part of the pipe which is an object under test when the non-destructive test is performed by radioactivity transmission and performs the action by configuring a pipe seating plate (110) having a regular size and shape and having the bottom directly seated on the pipe; forming a pipe housing part (150), capable of housing a partial section of the pipe, on the bottom of the pipe seating plate (110); forming a shielding material inserting part (120), capable of embedding one or more lead plates (10), at an outer side of the pipe seating plate (110); and configuring a cover (130), capable of stably embedding the shielding material insertion part (120) by preventing the shielding material insertion part (120) from being separated, at a front, a rear, a left, a right and an upper side of the shielding material insertion part (120). |
