The present invention relates to a radiation protection arrangement, in particular for attachment to a support rail, which is attached to a side of a treatment table, comprising: a holder on which a radiation protection drape is arranged, wherein the holder is attachable to the support rail and comprises a fastening means with which the holder can be fastened to the support rail. The fastening means is formed on a side of the holder and comprises at least one first bracket part and at least one second bracket part. The first and the second bracket parts each have an L-shaped profile with a first leg and a second leg, wherein the first and the second bracket parts are arranged such that the first legs are aligned in parallel and the second legs face each other. The first bracket part is arranged at an upper edge of the holder and the second bracket part is arranged at the lower edge of the holder. Consequently, the first bracket part is arranged relative to a longitudinal direction of the holder at a first distance from the second bracket part such that the holder in a first position in which the holder is pivoted relative to the support rail can be brought into contact with the support rail. With a pivoting motion the holder can be brought into a second position in which the holder is fastened to the support rail.
