ABSTRACT:
A marking device, preferably for use with x-ray film to be exposed, has an indicia supporting member that is transparent to the x-ray energy, at least one indicia opaque to the x-ray energy, a movable cover shield also opaque to the x-ray energy, an attaching means for temporarily securing the device to an x-ray film or a film cassette, and a removable carrying case. The cover shield is moved from a shielding position relative to the indicia to an non-shielding position relative to the indicia. When the indicia is not shielded then the indicia appears on the exposed x-ray film. The carrying case substantially encloses the attaching means to prevent its contamination when the marking device is not in use, and includes means for attaching the case and device to the user in a visible and accessible location, as well as containing radio opaque indicia for marking the film with additional information.
