Details: This Civil defense era geiger counter, Victoreen CD V-700 Model 6B. May look slightly used cosmetically. Three ranges allow low level gamma radiation measurement at 0 - 0.5 mR/hr, 0 - 5.0 mR/hr and 0 - 50.0 mR/hr. included probe detects beta radiation and gamma radiation with the detecting wand's beta shield open, or gammas only when the shield is closed. The CD V-700, as a true Geiger Counter, is capable of measuring ambient background levels of gamma radiation and detecting the presence of beta radiation in the environment, and thus can be used to detect such common low-level radioactive artifacts as uranium-doped marbles, Fiestaware plates and radium watch faces. The CD V-700s main purpose was as a peacetime training instrument and for use in checking food and shelter entrances for low levels of fallout contamination. This Victoreen Model 6B geiger counter is considered the 'work horse' of the emergency response community with thousands in use today across America. This model requires 4 common 1.5v D-Cell batteries. The CD V-700s main purpose was as a peacetime training instrument and for use in checking food and shelter entrances for fallout contamination. While this unit will field test food for higher unsafe levels, lower unsafe level testing must be done in labs by trained personnel.
The detector on the CD V-700 is a Geiger-Mueller (GM) tube. It measures gamma and also beta radiation.
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.
The CD V-700 is very well suited for verifying successful decontamination and/or checking for low-level contamination in food or water.
Developed to check food and shelter entrances for fallout contamination Still is use by first responders
The ruggedized lens provided more EMP protection than the original meter face
