RadAngel gamma ray radiation spectrometer

A perfect entry-level CZT-based gamma ray isotope detector

RadAngel CZT-based gamma-ray spectrometer

The RadAngel is an affordable CZT-based gamma-ray spectrometer.

RadAngel is an ideal entry level, portable gamma-ray spectrometer that can be utilised for educational purposes in teaching concepts of radiation as well as for training in the use of radiation sensors.

You might see this detector listed as RadAngel for School – the detectors are the same only the name is different.

Its compact size and quick set-up time make it ideally suited for individual or small group projects, laboratory-based teaching, classroom demonstrations and field studies.

The RadAngel is an affordable CZT-based lightweight, portable, high-performance gamma-ray radiation detector. This instrument utilizes a Cadmium Zinc Telluride (CZT) solid state detector, which enables room temperature operation with excellent energy resolution. The unit is completely self-contained, with a built-in detector, amplifiers, power supply and communications. The digitized detector signals are sent to a PC via the mini-USB which also powers the unit, so no external supply is required.

A full range of CZT-based or scintillator-based gamma-ray spectrometers is available.

Kromek offers a full range of room temperature radiation spectrometers, the RadAngel is a perfect entry-level CZT-based detector, for more intensive applications you should look at our range of GR CZT-based gamma-ray spectrometers or our range of scintillator-based radiation detectors.
