Detect Radioactive and Nuclear Materials

SPECTRA is a highly sensitive, compact device for detecting and localising radioactive and nuclear materials via gamma and neutron radiation, as well as radionuclides by an amplitude gamma spectrum. It uses a silicon solid state photomultiplier, with sensitive CsI scintillation detectors for gamma and LiI for neutron radiation.

  • Measure dose rate H*(10) of gamma, X-ray and neutron radiation
  • Measure dose H*(10) of gamma and X-ray radiation
  • Determine gamma and neutron radiation intensity
  • Identify radionuclides by their amplitude gamma spectra (2048 channels)

Instant Alerts

Identification is performed instantly at the slightest change of gamma or neutron level, using a powerful new search algorithm and a fast CPU for processing spectra. Data is displayed for you straight away in real time.

There are four independent threshold levels:

  • Search threshold level: Photon and neutron ionising radiation count rate from the detector
  • Safety threshold level: Photon and neutron ionising radiation DER

When these levels are exceeded, you’re notified immediately by audio alarms and vibration. A colour-coded light gives you instant indication of the type of radiation detected: red for gamma and blue for neutron.

Analyse Data on a PC

SPECTRA can be connected to a PC via USB for transferring data. Up to 250 complete gamma radiation spectra can be stored.

You can view measurement results and critical events, and compile reports of dosimetric information. Radiation monitoring information can also be displayed on a map, to give you a clear picture of the area, using data from the integrated GPS/GLONASS receiver.
