UAC offered the only completely “transisterized miracle Geiger counter” in 1955. It had no vibrators, no tubes, no repairs and almost indestructible. In 1958, UAC was a division of Universal Transistor Products Corporation. Two models were offered. The Walking Stick Geiger Counter Model UAC 402 sold for $99.50. The walking stick was 40” long x 2” diameter and contained a GM tube. It weighed less than 3 lbs. and could provide over 1000 hrs of continuous use on two 15 cent flashlight batteries. A cable connects the Walking Stick to a transistor audio amplifier that the user can carrying in a shirt pocket. The amplifier operates on a set of earphone batteries. It also contained a flashing neon light unit. An aluminum shield was provided for beta discrimination. It had a baked hammertone finish on drawn aluminum.

The Model 522 came in two versions. The Model 522A was a probe desktop unit with probe for hospital or laboratory scintillation counting of patients. The Model 522B was a portable suitcase type unit for use in doctor's offices, at bedside in hospitals or at home, in an ambulance and in laboratories. It could be used for evaluation of thyroid activity, brain tumor localization, blood volume and cardiac output, and treatment monitoring of malignancies. It could be used with lead shielded for directionality. It had a 2" crystal with the lead reducing the opening to 1/4 in, 1/2 in, 1 in and 1-1/2 in. The unit weighed 23 lbs. including lead probe in a watertight 18 in aluminum case with luggage-style handle. It had nickel cadmium cells which can be charged and operated for 50 hours. It can also use 1-1/2 volt D cell flashlight batteries. In 1956, the unit cost $1095 for a 1 in x 1 in sodium iodide crystal or $1395 with a 2 in x 1-1/4 in crystal.

The Model V-700 was introduced in 1958 as a hand portable radiation monitoring instrument designed "to enable anyone to quickly and easily measure low-level radiation resulting from contamination by radioactive fallout or nuclear explosions". It was an all transistorized unit and operates from standard flashlight batteries. The range is from 0.5, 5 and 50 mR/h and 0-500 cpm with factor scale of x1, x10 and x100. The unit measures 3 in x 4 in x 7 in and weighs 4.5 lbs. The UAC Model V-700T was a more rugged unit and completely transistorized power supply to eliminate costly breakdowns. It was even lighter weighing 3.5 lbs. The unit came in a bright yellow baked gloss enamel and was waterproof, moisture-proof, and fungus proof to meet military specifications.

The UAC Model V-710-44 was a gamma survey meter with built-in dosimeter charger. The dosimeter charge excepts standard dosimeter pens in a few seconds. A UAC dosimeter can be mounted on the meter allowing the operator to read cumulative dosages from 200 mR to 100 R. The unit has ranges of 0.5, 5 and 50 R/h. It has an ionization chamber, air-filled and hermetically sealed in a steel enclosure. It measured 8-3/4 in x 4-3/4 in x 4-1/2 in and weighed 4 lbs. It also came in a bright yellow durable, baked gloss enamel case.
