PROBLEM TO BE SOLVED: To provide a screen that changes an installation angle freely and, what is more, can securely prevent radiation from leaking from joints. SOLUTION: A screen for protecting against radiation includes screens 1 and 2 that are connected with each other in the position of a joint 7 so that the screens 1 and 2 can revolve and protection covers 3 and 4 that are mounted on the screens 1 and 2 to shield the joint 7. The protection covers 3 and 4 are also mounted with the sides of the tips of the covers 3 and 4 overlapping with the side end parts of the screens 1 and 2 so as to shield the joint 7 over the whole revolution range. Moreover, support leg members 6 on the side of the revolution center of the screens 1 and 2 which are connected with each other so that they can revolve are mounted in staggered positions where the members 6 do not interfere with each other when they revolve.
