Hi, I'm looking for solution: I need color day/night camera (ccd or cmos) for monitoring radiotherapy room with x-rays source. When I tray noname color camera ( 540 Tvl, day/night mode,DC drive lens ), x-rays source destroyed more ccd pixels - looks like white small points on screen, like dust. Can I use some x-rays filter on lens or special camera cover ? Can you help me somebody, plz ? Thanks.
