Geiger Counter and Survey Meters from the Civil Defense for us in the U.S. RADEF program.
During the 1950s, following the development of nuclear weapons by the Soviet Union, the U.S. federal government urged the states to obtain radiological instrumentation for use in the event of a possible nuclear attack.
It is obvious that the CD in CD V stands for Civil Defense. The V though, has been a bit of a mystery. It turns out that it is the roman numeral five. More specifically, it refers to the chapter in the FCDA manual that contained the details regarding the matching funds that the federal government provided the states for the purchase of radiological equipment for civil defense (Marlow Stangler, personal communication). It is often the case that the CD and V are grouped together (e.g., CDV-700). Nevertheless, the original approach for identifying civil defense instruments was to have the CD separated from the rest of the designation (e.g., CD V-700).
It should be noted that the best buy is the CD V-777 Instrument Sets, because it contains all the CD meters shown in the video, plus a few other items.
