Collection of Radiation Instrument Advertisements from 1940-1960

As the development of portable radiation instruments emerged, competition began to develop among the manufactures and the race was on for advertising and marketing. The advertisements presented in this section are a sampling of the variety of approaches beginning in the late 1940's through 1960.

The following is an another example of a Detectron advertisement. It states “In 1849, all you needed was a pan and some luck in avoiding Indians, but in 1955 you’ve got to choose the best instrument for your purse and purpose”. Also shown are the Model DG-2 which was the first detector sold by Detectron in the late 1940's and sold for $37.50. On the high price end at $515.00 is the Model DS-235, which was a gun type instrument with a high sensitivity scintillation detector as opposed to the standard Geiger counter.

The Detectron 390-B was described as the “New Bismuth Nucliometer” and was designed to aid in locating mineral deposits. It contained 24 bismuth geiger tubes. The insides of the tubes have a bismuth-coated screen that ionizes the gas more efficiently, thus increasing the sensitivity over normal geiger counters by a factor of 2.5 to 5. This sensitivity increase is useful for weak or distant anomalies. The unit would have sensitivity with 24 tubes from 50-100 times higher than a single geiger tube. Sensitivity was 0.005 mR/h to 0.5 mR/h. It originally sold for $1295 in 1955.

Omaha Scientific offered a line of radiation detectors in the 1950's. An example of the advertisement for the Model TX-8 is shown below. During that period, most of the commercial low cost detectors were advertised for uranium prospecting which became a popular recreational past time for prospectors and hobbiest. It advertised as the "World's Largest Exclusive Manufacturers of Geiger Counters for Prospectors".

Precision Radiation Instruments (PRI) produced a line of radiation detectors beginning in the late 1940's. The push was on for compact, lightweight geiger counters useful for the early stages of the uranium rush. The Model 101 shown below was their first product and is illustrated in the 1948 ad as being very light weight, being held by a single finger.

Also during the late 1940's, the U.S. government began offering uranium prospectors rewards of up to $10,000 for locating radioactive ore deposits. At the time, the government needed to find uranium ore deposits to meet the growing demand for uranium for developing atomic weapons program. The ad below is for PRI's early model which weighed only 2 lbs. and sold for $49.50.

In the mid-1940's, the detection business took a significant leap in sensitivity with the introduction of the sodium iodide scintillation detector. Being a solid material as opposed to a gas in the geiger counters, its sensitivity to stopping gammas increase significantly. As such, a prospector could detect the uranium at much greater distances, even riding in a car or airplane. The Model 111C shown below was one of the most popular gun type instruments which came in a shiny chrome casing. The battery pack on the bottom right of the picture detached and would be carried on the belt leaving the gun type probe with the pistol grip for pointing and probing cracks and crevices. PRI advertised as "The Most Versatile Instrument in the Uranium Field". It was considerably more expensive, selling for $695.00 in 1955.

The Royal Scintillator was initially introduced in 1947. The unit is a scintillator probe with accompanying control unit in a briefcase. An improved version of the unit was still be offered in 1955. The advertisement asked “Why Search for Uranium with a Horse and Buggy?” These larger format detectors were still portable but bulkier and heavier, partly due to the large size scintillation detector and batteries. In addition, the instrument had such a large detector crystal size that it could be used for Aerial Prospecting for uranium.

In contrast, manufactures such as El-Tronics were also producing small, compact geiger counters including the Ura-Finder from the 1950's shown below. The Ura-Finder was a pocket-sized unit which could be used to just testing various rocks to see if they were radioactive. The ad states "Now! Uranium Prospecting Easier Than Ever Before - Pocket Size Geiger Counter.

El-Tronics Ura-Finder Ad 1950's

Universal Atomics produced a line of transistorized geiger counters in the mid-1950's, including the instruments with long extension probes and gun formats. The long extension probe instruments allow the prospector to carry the electronics and batteries in a shoulder strap case and use the extension probe with the detector on the end to probe cracks and crevices which might reveal uranium ore veins. The ad states "Now! For The First Time Since the Discovery of Uranium - Miracle Geiger Counters".

The Radiac Company was a major distributor of radiation detection equipment. All of the Radiac Company product line was produced by other radiation detection manufacturers. One example is the Sniffer, a compact, portable instrument that easily fit in your hand. The ad stated "Discover Uranium - Win Huge U.S. Gov't. Cash Awards - Locate Radioactive Ores with The Sniffer". The company was very good at advertising and providing very clever names to their product line that attracted the reader.

One of the more interesting product lines was from White's Electronics, which produced the Oremaster series in the 1950.s The ad below states "Strike it Rich with Oremaster's Rockhound Super Geiger Counter". The instruments provided higher sensitivity than normal geiger counters and a large 4.5" meter for ease of viewing.

Victoreen produced undoubtedly the most extensive line of radiation instruments from the 1930's on. One example of a popular instrument from the 1950's was the Vic-Tic which could be used to "Find a Fortune on Vacation, Hunting and Fishing Trips - Pin-Point Uranium". It came in a very shiny gold and bright red colors.

An example of one of the original style Cutie Pies is shown below for Technical Associates. It also was housed in a brushed aluminum casing for easy decontamination. This particular unit has a shield that could be placed over the nose to reject beta particles. Many versions of the Cutie Pie evolved over the 1950's.

Beckman's product line included the MX series for uranium prospecting as shown below. It was a low cost unit which was simple to operate with an on-off switch, long battery life, but employed only a set of headphones for audio tones. For prospecting, it was often difficult if not tedious to continuously look at a the needle movement on the meter and as such, the tones or clicks from a headset proved more popular.

Beckman MX-8 Ad 1949

Stowers and Son produced an instrument called the Spotter, which provided a detachable probe. The probe could either be secured to the front of the instrument or detached and used for probing cracks and crevices with a five foot cable. The 1955 Spotter ad is shown below.
