Civil Defense Radiation Meters (Most of Them)
I hope you will enjoy this page of radiation meters. Sorry about the lack of information and pictures. Please visit www.civildefensemuseum.com for more information (and pictures). NOTE: all pictures are from ebay.com, which is why some may look odd/funny/weird.

CD V-700
A low range Geiger Counter. |
CD V-710
Requires two 22.5 volt batteries and one D sized battery. Knobs are known to break and most units won't even do a circuit check. They normally come in a very cheap plastic case (as seen at right).

AN/PDR 56
The AN/PDR-56 (series A through E and G alpha detector "windows." through H) (fig. 8-8) is the Navy's standard alpha The AN/PDR-56 has a meter readout calisurvey meter. It is used to locate and measure brated in four ranges of counts per minute (c/min): alpha contamination of (1) the skin and clothing of 0 to 1,000, 0 to 10,000, 0 to 100,000, and 0 to personnel and (2) the surfaces of equipment, 1,000,000. These values are directly related to buildings, or land. surface plutonium-239 contamination levels of 0-
The detector of an AN/PDR-56 is of the 10, 0-100, 0-1,000, and 0-10,000 micrograms per scintillation type. Alpha scintillation detectors are square meter (ng/m 2 ). extremely fragile devices by necessity. Detection involves (1) the release of alpha particle energy in Beta-Gamma Radiacs a phosphor with the resultant production of a scintillation of light and (2) the conversion of the energy in the light scintillation to electrical energy in a photomultiplier (PM) tube. Since the PM tube is light sensitive, the phosphor must be protected from ambient light.
