Gamma Ray Spectrometers

More about GRS-10, GRS-16The GRS-10 and GRS-16 systems are intelligent, self calibrating Gamma Ray spectrometers using NaI (Tl) large volume detector arrays. Simple serial (RS-232) communications protocol allows them to be connected to any PC compatible computer system. All dedicated electronics modules are housed within the detector container. By virtue of application software any personal computer may be transformed into a sophisticated Gamma spectrum analyzer.

The GRS-10 or GRS-16 series of spectrometers are widely used in geological and geophysical exploration and mapping as well as in environmental and nuclear surveillance.

Individual, independent, detector processing provides real time gain and linearity correction. PEI's ongoing research to improve the system stabilization algorithms make these spectrometer systems fully automated and self stabilizing on natural radioactive elements. This eliminates the requirement for regular, time consuming, and frequent system checking and re-calibration by the user. Furthermore it provides excellent accuracy and reliability of the gamma measurements. Read more...

More about portable spectrometerThe GRS-2 is an intelligent portable Gamma Ray Spectrometer designed to process and store data from up to two Gamma Ray Detectors.

The smallest detector used is a NaI(Tl) 3in (76mm) in length and 3in (76mm) in diameter. Such a detector is usually mounted together with the battery and hand carried or fastened on a backpack. Larger detector volumes of up to 4 liter or larger are carried on a backpack or placed on a push-pull cart with or without a motorized drive. The portable spectrometer GRS-2 is designed for fast and reliable ground surveys or monitoring of larger areas where radioactive materials may be buried. Read more ...
