Radiation Meter Calibration

Reed Research Reactor

Reed Research Reactor is licensed by the State of Oregon to perform calibrations of radiation survey meters.

The cost is generally $50 per meter. If the meter has interchangeable probes, it is $50 for each probe. Add shipping if you wish us to ship it to you. 

We use a calibrated pulser for count rate meters and then determine the efficiency with a radiation source. Normal sources in use are Cs-137 and Pu-239. Other sources are available if needed.

For dose rate meters, we use a JL Shepherd Calibrator with a 900 mCi source on our 6 meter calibration range. There are four lead shields when lower dose rates are desired.

We generally do NOT perform meter repair.
