Vintage 1954 Precision Radiation Instruments Inc. Model # 111B De Luxe “Scintillator” radiation detector it includes the original leather storage case. This unit is S/N# 211TTB6584, AEC# SBX-11A. These units are 100+ times more sensitive than a normal Geiger counter I have been told. This particular unit came from a collector that owned and repaired radiation detection equipment. We would like to keep it but we have too much stuff around here and this one is in nice enough physical condition to put it in a museum. The Chrome is very good - excellent estimate a 8.5+ out of 10, the electronics in the detector head are complete and are in excellent overall physical condition. The leather case is just in fair condition and a few seams may need re-stitching. We are unable to test this item (no batteries, etc) so we are selling it for parts or repairs per eBay protocol. Information from (ORAU) Oak Ridge Associated Universities excellent web site: The Model 111B “Scintillator” and “De Luxe Scintillator” were introduced in late 1954. The detector had a “gun” type handle design. The unique feature of this unit was the highly-polished chrome surface. It was the first “percent meter” to readout in percentage of uranium. The meter is large at 3” in diameter. The Model 111B Scintillator nose houses a 1.5” x 1” sodium iodide detector which is 200 times more sensitive than the standard GM tube. The photomultiplier tube is housed in a magnetic shield. This made the 111B an ideal tool for uranium exploration from moving vehicles and an airplane. The probe is also waterproof and tropicalized. The meter was calibrated for percent uranium. There were six scale settings from 0.025, 0.05, 0.25, 0.5, 2.5 and 5 mR/h. The battery box can be detached and carried on the belt and weighs less than 4 lbs. It used four 1.5V flashlight, two 22.5 and two 67.5 volt batteries. The probe size is 3-3/4” x 13.5” and weighs 7.5 lbs. The battery box is 5-5/8” x 4-5/8” x 3”. A red flag warning signal guards against leaving the instrument turned on. The unit is easy to use by untrained personnel. It sold for $495 in 1954. In 1955, the Model 111B was offered by the Radiac Company as the “Percentometer” which allowed a direct reading for on-the-spot uranium radioactive material assays.
