The MD Series of standard scintillation detectors provides customers with the capability of measuring gamma and beta emitting radionuclide for a wide variety of applications. The detectors consist of one or two scintillators (gamma or beta) optically coupled to a photomultiplier (PM) tube via a Lucite light pipe. A reference Light Emitting Diode (LED) and a temperature sensor are imbedded in the Lucite pipe.
These detectors operate with a unique gain stabilization circuitry for temperature-compensated drift-free operation, resulting in improved accuracy and extended calibration cycles.
The MD455E, MD55EB1, MD55EV1, MD55EV2 and MD55EV5 are capable of measuring extended operating ranges of up to 11 decades of linear activity from environmental effluent release levels to accident range.
