The invention relates to a movable radiation protection arrangement comprising a frame which is open on one side and which comprises a lower part (100) and an upper part (200), said upper part being vertically adjustable relative to the lower part, and comprising at least two flexible radiation protection curtains for protecting against radiation, preferably X-ray radiation. A first (420, 422) of the at least two radiation protection curtains is attached to the lower part (100) of the frame and extends preferably up to the lower edge of the frame, and a second (410) of the at least two radiation protection curtains is attached to the upper part (200) of the frame and is designed such that the at least two radiation protection curtains overlap in each vertical position in which the upper part is adjusted relative to the lower part.
