To protect doctors and other personnel from stray radiation when using therapeutic or diagnostic X-ray or other radiation apparatus, a lead apron is suspended from a dolly or carriage rolling in a track system secured to the ceiling in which the radiation apparatus is located. The dolly or carriage can be similar to that of already existing rolling equipment. It has a centrally positioned hanger arrangement which has a turning hanger secured to the dolly to which a tension spring is attached which supports the lead apron hanger, by having attached thereto an element generally in the form of a clothes hanger from which the apron, itself, is suspended by means of an adjustable strap suspension. Preferably, an intermediate strap suspension is further interposed between the hanger and holding spring which, in turn, is supported from a swing arm attached to the dolly or carriage, the swing arm permitting lateral excursion matched preferably to the lateral swing of diagnostic apparatus, such as a fluoroscopy monitor. The spring should be sufficiently strong to support the weight of standard lead aprons with an elongation of, preferably, less than its normal, unstressed length.
