  Radioactivity Measurements Laboratory

This laboratory is equipped for the measurement of a , b and g activities in environmental samples.

  • a - spectrometry systems
    MCB and software for the acquisition and treatment of a spectra (Maestro 3.2 for Windows 95, EG&G Ortec), with 18 silicon semiconductor detectors.
  • g – spectrometry systems
    Five MCBs, connected to one Ge(Li), one LEPS and five HpGe detectors, one of these being a well-type low-background detector.
    Software for spectra analyses, MAESTRO I and II (EG&G Ortec), SAMPO 90 (Canberra), SILGAMMA and GAMMAPLUS (Silena), as well as internally developed packages like GAMACTIV.
    Spectrometer equipped with a NaI(Tl) detector suited for automatic food samples analyses.
  • Total a/b counting systems
    Two low-background gas flow proportional counters, one of them with automatic sample exchanger, and one b low-background (0,5 cpm) gas flow G.M. type counter.
  • Liquid scintillation counter
    The Beckman LS 6500 Scintillation System is designed to provide highly accurate automated counting of the level of beta radioactivity in samples containing nuclides such as 3H.
