We have the following measuring instruments for neutrons, photons and ions at our disposal. The energy ranges for which the instruments can be used are given in brackets.



Recoil proton detectors as neutron primary standard instruments

  • proportional counters (H2, CH4)
[10 keV < En < 2.5 MeV]
  • recoil proton telescopes PRT1 (2,5-20 MeV),
    PRT2 (20-70 MeV), PRT3 (50 - 200 MeV)
[2.5 MeV < En < 200 MeV]

Detectors for neutron time-of-flight spectrometry

  • 6Li glass scintillator
[0.1 keV < En < 0.25 MeV]
  • plastic scintillator
[100 keV < En < 1,5 MeV]
  • NE213 liquid scintillator
[1.5 MeV < En < 70 MeV]
  • 235U(n,f) fission ionization chamber
[0.1 MeV < En < 200 MeV]
  • 238U(n,f) fission ionization chamber
[1 MeV < En < 200 MeV]

Photon spectrometers for measurement in mixed neutron/photon radiation fields

  • NE213 liquid scintillator
[0.1 MeV < Eγ < 20 (70) MeV]
  • HPGe detector
[0.1 MeV < Eγ < 20 MeV]

Ion dosimetry

  • water calorimeter (portable)
  • ionization chambers (also for use in a water phantom)
