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 (BSS)
  • Single sphere neutron spectrometer (SP2)
  • Mobile gamma spectrometry and survey units (HERMES)

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

HERMES systems are portable, easily deployable units designed to perform field measurements of gamma radiation or gamma spectrometry analysis, for applications such as radiation monitoring, geology research, laboratory analysis, environmental survey, etc.

GSU gamma spectrometry unit is composed of a 2”x2” NaI(Tl) detector with MCA, installed inside a 5 cm thick lead shielding well, performing high sensitivity gamma spectrometry and specific activity measurements.
