"Zeuto" Alpha Meter from the Metallurgical Laboratory (1943-1946) |
|
| The Zeuto seems to have
been the second survey instrument designed exclusively for measuring alpha
contamination (the first was the "Pluto"). It was
developed by Francis Shonka at the University of Chicago's Metallurgical
Laboratory during World War II. "Zeuto" is a
combination of the names "Zeus" (another survey instrument
developed by Shonka) and "Pluto."
The identification towards the lower left of the photo reads "An Instrument Section Product, Metallurgical Laboratory, Univ. of Chicago." A calibration curve dated March 26, 1946 is taped on the left end of the instrument. It converts the unitless reading on the meter into disintegrations per minute. The original description of the Zeuto is found in MDDC-117. Chamber: 1" x 5" x 3", thin plastic window protected by wire screen on bottom (ca. 3" x 5") Range: 0 - 5 (no units) Size: 5.5" x 10.5" x 4.5" Donated by Herbert Clark |
