Abstract: A radiographic projector for housing and projecting a radioisotope for use in radiography is described. The front end of the projector has a chamfered surface for receiving an ancillary shielding component. The material used for the front end surface of the projector is tungsten powder in a less dense material matrix. A locking mechanism for a projector is described, including a locking bar for locking a source holder in the projector. The locking mechanism includes an interlock section for retaining the locking bar in an unlocked position while a source holder is not in its storage position, and a latch section for latching the locking bar in the unlocked position prior to engagement of the interlock section. A holster for mounting a radiographic projector and a refraction cage for a remote windout mechanism are also described.

Abstract: A radiographic projector (10) for housing and projecting a radioisotope for use in radiography is described. The front end of the projector has a chamfered surface (12) for receiving an ancillary shielding component. The material used for the front end surface of the projector is tungsten powder in a less dense material matrix. A locking mechanism (30) for a projector is described, including a locking bar for locking a source holder in the projector. The locking mechanism includes an interlock section for retaining the locking bar in an unlocked position while a source holder is not in its storage position, and a latch section for latching the locking bar in the unlocked position prior to engagement of the interlock section.
