DCA 3090-3 Area Monitor
The Model 3090-3 Area Alarm Monitor measures radiation field intensities from x-ray or gamma radiation sources in the range of 1mR/h to 100R/h. The internal detector will measure radiation in the immediate vicinity of the instrument while the remote probe can be used to measure radiation up to 300ft. from the instrument, including exterior and underwater monitoring locations. The internal and optional external detectors are Geiger-Mueller tubes. When the external detector is plugged into the readout, the internal detector is disabled. The detectors are energy compensated to obtain good energy responses. Four easily accessible calibration potentiometers are provided to accurately calibrate each instrument across their entire indicating range. The alarm setting can be observed, even in a radiation field, by pressing the “check” button on the front panel. The alarm “set” potentiometer is on the front panel also. Changes made in the “set” potentiometer can be observed using the “check” button. An alarm speaker volume control is available on the front panel for reducing the sound level in locations where it would be irritating or unwanted. A red flashing light on the readout is also used to indicate an alarm condition. All alarms are deactivated by pressing the alarm reset switch. The accessories available for use with the area monitors include a remote readout and a door interlock kit. In addition, repair kits are available for the external probes.

John Diehl, CHP –
Simple to use; however the boards inside the probe need to be better isolated from shock and then the probe needs to be plastidipped to seal it from water intrusion. We still use these where I work for surveying inside the spent fuel pools, albeit with the above mentioned modifications. These units are analogue, so there is not data telemetry. ON the other hand, these units are analogue so there is no painful set up requiring computers and you don’t have to be a programmer to set one up. They are far more rugged than the comparable digital units from a certain French company. However, they have five decade resisters so you must calibrate and adjust all five decades and potentially adjust each potentiometer.
