CD V-700 Geiger Counter
Newly Calibrated Shipment In Stock
The detector on the CD V-700 is a Geiger-Mueller (GM) tube. It measures gamma radiation. It has a check source on the side and a headphone jack. The range selector switch allows you to measure up to 50 mR/hr. A milliroentgen (mR) is one thousandth of a Roentgen (R). The probe on the CD V-700 has a section in the center which rotates to expose a window for also detecting beta. When the window is open it detects both beta and gamma. This survey meter is calibrated only for gamma radiation, so you can not get an accurate reading of the exposure rate from beta particles, only an indication of their presence.
The CD V-700 is a low-range meter more suited for peacetime use than the other two high-range CDV-715's and 717's. According to the xxxx FEMA publication #SM 320 "Fundamentals Course for Radiological Monitors" states: "It is only able to measure up to 50 mR/hr and unit may become "saturated" in a higher field of radiation and act erratically, even to the point of giving false low readings in radiation fields exceeding xxxx mR/hr (1 R/hr)."
However, it is well suited for verifying successful decontamination and/or checking for low-level contamination in food or water. But, as you'll see in the following section, detailing the most dangerous levels of radiation to be most concerned about, if you can only initially afford one survey meter, it needs to be a high-range meter first.
