Manufactured in the 1960s. This is an unused Civil Defense radiation survey meter, designed for measuring dangerous radiation levels after a nuclear explosion or major nuclear reactor power plant failure. A unique, and functional, historical object from the cold war era. Manual copy included. Checked using its“Circuit Check” function. Bulk-Storage. This meter may have minor scrapes. Rub marks and occasional dings and paint chips from bulk storage. Bulk-stored meters do not come with straps or their original individual boxes. They may also have early calibration tags. CD(Civil Defense) label on one side. PLEASE NOTE: Even though this meter passes its“circuit check” function. It may need calibration to be certain it will read correctly when needed. I include a note on cleaning the cable contacts, and provide a reference for calibration and ... morerepair, if you wish to have it accurately calibrated. Shipped with a fresh alkaline battery installed. In discussion with Victoreen. I asked: 1) Are these meters still serviceable? They are serviceable. 2) Would they be a good home-use instrument in case of a radiological event? Yes. 3) How delicate are they? They’re tough. They tend to read within 20% without calibration, which is about the accuracy that is necessary for home use. PLEASE NOTE: This is not a“Geiger Counter” for prospecting. Though designed like a Geiger Counter. It has an ion-chamber, not a Geiger-Muller sensing tube. It is shielded to detect only high-energy Beta(2 MEV and up) and Gamma radiation from a nuclear explosion or nearby high-energy ionizing radiation source. It will NOT detect mineral radiation, identify Uranium Oxide glass or sense your alpha-emitting smoke detector. It will NOT detect slightly radioactive steel, or titanium or tungsten isotopes. Meter scale is 0-5 R/Hr. Ranges are: X100. X10, X1, X0.1. The meter separates into three components. The ion chamber in the bottom can extend 25-feet on a cable. This allows the detector to be placed outside, while the meter is read insi
