Spectrometry systems


ELSE NUCLEAR, thanks to collaborations with universities and international research centres, achieved important results in developing highly specialized spectrometry systems for gamma and neutron radiation. The devices designed so far provide fast and reliable spectrometry measurements in a wide range of conditions.

Up to date, ELSE NUCLEAR supplied gamma and neutron spectrometry systems to research facilities, steel foundries, nuclear power plants, and particle accelerator facilities.

Discover our spectrometry systems:

  • Gamma spectrometry unit with NaI(Tl) scintillator detector (GSU, GSU DYMO)
  • Hand-held spectrometer for gamma radiation (B-RAD)
  • Bonner sphere set for neutron spectrometry (BONNER SPHERE SPECTROMETER)
  • Single sphere neutron spectrometer (SP2)

The Bonner sphere spectrometer consists in an array of thermal neutron detectors (He-3 proportional counters), each housed in a spherical polyethylene moderator of different diameters. 

B-RAD is a portable, hand-held gamma monitor, capable of providing the photon spectra in presence of strong electromagnetic fields.

The single sphere neutron spectrometer (SP2) is a unique tool that allows performing active neutron spectrometry measurements by employing a single device instead of the usual multi-sphere Bonner spectrometers.

GSU gamma spectrometry unit is composed of a 3”x3” NaI(Tl) detector coupled to a multi-channel analyser (MCA), installed inside a 5 cm thick lead shielding. This setup allows to perform high sensitivity gamma spectrometry.
