A swivel mounting bracket for attachment to an electrical junction box and to a detector device, the swivel mounting bracket having two identical fittings. Each fitting has an internal passageway which progresses around a 90.degree. bend, and each fitting has a mounting plate at one end and a mounting base at the other end, positioned orthogonal to each other. Each mounting plate has an arcuate groove with an internal shoulder for facilitating attachment to a mounting base. The mounting base of one fitting is attachable to the mounting plate of the other fitting, and the respective remaining fitting ends are attached to the junction box at a detector.

Explosion-proof swivel mounting bracket

Apparatus for detecting radiation with a light-sensitive radiation receiving tube enclosed in a housing behind a transparent window, the invention including an auxiliary internal light source for testing the optical transmissive properties of the window and including a shielding member between the auxiliary light source and the radiation-receiving tube and a reflective mirror for directing light from the auxiliary light source toward the window for reflection off an external interface surface thereof toward the radiation-receiving tube.
