In the present invention, provided is a shielding device for radiographic inspection which comprises: a base frame having a ring structure which is inserted and installed into the outside of a pipe to be inspected a shielding frame which is connected and installed to be able to slide and move on the base frame to be able to move along the outer circumference of the pipe and has a shielding material therein a cassette frame which is connected and installed to be able to slide and move on the shielding frame to be arranged between the outside of the pipe and the shielding frame and has a film and a radiation emission unit which is connected and installed to be able to slide and move on the base frame to be arranged to face the shielding frame and has a radiation source for emitting radiation in the direction of the film. The shielding device for radiographic inspection slides and moves the shielding frame to a location to be photographed on the base frame after inserting and installing the base frame into the outside of the pipe to be inspected. Radiation, emitted by the radiation emission unit, is released in the direction of the shielding frame while penetrating the pipe. Accordingly, as an image of the pipe is photographed on the film in the cassette frame installed on the shielding frame, radiation is emitted to only a range of the film, stable shielding is possible at the same time, and a process for changing the location of the portion to be photographed can be performed in an easy manner.COPYRIGHT KIPO 2018본 발명은, 검사대상의 배관 외측에 삽입 설치하는 링 구조의 베이스프레임, 배관 외측 둘레를 따라 이동할 수 있도록 베이스프레임에 슬라이딩 이동 가능하게 연결 설치하며, 내부에는 차폐물질을 구비하는 차폐프레임, 배관 외측과 차폐프레임 사이에 배치되도록 차폐프레임에 슬라이딩 이동 가능하게 연결 설치하며, 필름을 구비하는 카세트프레임, 차폐프레임에 대향 배치되도록 베이스프레임에 슬라이딩 이동 가능하게 연결 설치하며, 필름 방향으로 방사선을 조사하는 방사선원을 구비하는 방사선조사부를 포함하는 방사선검사용 차폐장치를 제공한다.이와 같은, 방사선검사용 차폐장치는, 베이스프레임을 검사대상의 배관 외측에 삽입 설치한 후, 촬영하고자 하는 위치로 차폐프레임을 베이스프레임 상에서 슬라이딩 이동되게 하고, 방사선조사부에서 조사되는 방사선이 배관을 투과하면서 차폐프레임 방향으로 방출된다. 따라서, 차폐프레임에 설치된 카세트프레임 내
