  • Thin scintillation detector with lead collimated low energy gamma probe
  • Aluminium end window

An end window scintillation probe designed to be an equivalent to the Mini 44A. It incorporates a Ø32 x 2.5 mm thick NaI(Tl) crystal mounted on an aluminium window and is fitted with an internal 3,15 mm lead collimator to reduce background counts. Perfekt for survey of low energy gamma emitting isotopes like I-125 and Fe-55.
