Abstract
An improved safety housing for a radiation source used in polymerization of materials. The housing includes an interlock feature which prevents activation of the source unless the shield is placed upon the work piece. A spring loaded switch on the surface which abuts the work piece and a second magnetic switch are used to prevent accidental activation. The unit uses a mechanically interlocking locator plate which is aligned in advance of the insertion of the housing into it, and shields the operator from any stray radiation when in use.
