|
|
This particular dosimeter was manufactured by the Keleket Corporation of Covington, Kentucky. Quoting a 1954 advertisement "Accurate . . . Economical . . . Easy-to-operate . . . Keleket Pocket Dosimeter Model K-112 AEC #PIC-7A3. enables X-ray or radioisotope personnel to keep constant check on accumulated X- and gamma radiation exposure. Clips conveniently to pocket. Withstands severe abuse. Only 3 5/8" long. Capacity: 200 mr. Also high range models to 100 roentgens. Charged on Keleket K-135 Charging unit." |

| The scale (above right)
is somewhat
hard to read. The top line is "milliroentgens."
Below that is the scale running from 0 to 200, and below that it reads
"Tracerlab Keleket Model K-112"
Size: 3.75" long and 0.5" in diameter Range: 0 - 200 mR Weight: ca. 0.5 oz. According to the 1952 AEC Instrument Catalog, the Model K-112 supersedes the Models K-110, K-109 and K-111. Its overall accuracy is said to be ± 5% at any point and ± 5% between 250 and 1200 keV. References Advertisement in the January 1954 issue of Nucleonics p 64. AEC Radiation Instrument Catalog No. 3.
