X-ray analysis apparatus with detector window protection feature

A method for testing an object with X-rays, the method comprising:

• providing a radiation emitting, material testing device which includes a hand-held device housing;
• a radiation emitter in the device housing and configured to emit radiation directed at the test object;
• a radiation detector housed inside a detector front housing closed by a sealing window and configured to detect radiation of the test object, proximately caused by said object having been exposed the radiation of the emitter;
• a user actuated trigger switch for the radiation emitter;
• and a protective cover mechanism affixed to the testing device and configured to have at least a closed position covering or obstructing access to said sealing window and an open position exposing said sealing window to allow the un-obstructed passage of radiation therethrough, wherein the detector front housing is housed within the device housing and the sealing window is configured as s art of the detector front housing allowing radiation response to reach the detector, and, the detector front housing further comprising the protective cover mechanism being located between a sealing film and the sealing window and wherein said radiation emitter is located outside said detector front housing;
• and
• actuating said trigger switch to cause the protective cover mechanism to move to the open position.
