The Model 360 Pancake Probe has a large area mica window that has a thickness of 1.8 to 2.0 mg/cm2. This allows detection of alpha radiation as low as 3.0 MeV when in close proximity to the window. Beta radiation in excess of 35 keV and X-ray or gamma radiation greater than 6 keV will penetrate the window. The detector is provided with a BNC connector. It can be used with most count rate and survey meters which accept Geiger Mueller (GM) detectors operating at 900V DC.
