Model 115 "Super Scintillator" (1953) I found the following interesting information on the internet about the Model 115 "Super Scintillator": Manufactured by Precision Radiation Instruments of Los Angeles California, the Super Scintillator was one of the first survey instruments to employ a NaI scintillator. The NaI crystal, small by today s standards, was 1.5 x 1 . The electronics and probe were housed in a 5 x 11 x 14.5 case. Since the Super Scintillator was specifically designed for airborne and vehicle gamma surveys, it allowed the user to set a shorter time constant than was employed with typical hand-held systems this facilitated operation at high speeds. For surveys from aircraft, the manufacturer recommended speeds under 100 mph and altitudes of 50 to 100 feet. A pilot light was employed to guard against leaving the unit turned on. Two jacks were provided so that it could be connected to a continuous strip recorder. This particular instrument is of very early construction: the scale on the meter was numbered by hand and the small meter found in later versions on the outside of the case is missing in this example. A stamp in the instruction manual that came with the meter states that it was received by Radiation Instruments Branch, August 12, 1953 . Range: 0 0.025, 0 0.05, 0 0.25, 0 0.5, 0 2.5 and 0 5 mR/h. Batteries: eight 1.5 volt, four 67.5 volt, and two 22.5 volt Dimensions: 3.5" x 12" x 15" Weight: 16 pounds Price: $595.00 in 1954. The pictures below really dont do this Super Scintillator justice and I am sure that you will not be disappointed!
