CD Vremote sensor survey meter, is essentially and CD V gamma survey meter with a removable detector unit for making remote measurements to distances of 25 feet.
The ranges of this instrument is When properly calibrated, the response is within the range of plus or minus 20 percent of the true gamma dose rate from cobalt 60 or cesium when the cable is connected for remote sensor use. The instrument response is within plus or minus 5 percent of the meter indication when the cable is not in the circuit. This instrument is for use by radiological monitors in monitoring stations during the early period following a nuclear attack.
The instrument was designed to decrease the radiation exposure to the manua by enabling to obtain outside dose rate readings while utilizing the protection of some portion of the structure.
