Radhound - Sodium Iodide Probes
SS404 Al Probe
Thin-crystal NaI(Tl) probe for low energy gamma measurement. An end window scintillation probe designed to be an equivalent to the 44A. It incorporates a Ø32 x 2.5mm thick NaI(Tl) crystal mounted on an aluminium window and is fitted with an internal 3.15mm lead collimator to reduce background counts.
SS404 Be Probe
Thin-crystal NaI(Tl) probe for low energy gamma measurement. Similar to the SS404 Al but is fitted with a beryllium window, which extends the
low energy response down to 5 keV, making it suitable for counting 55Fe.
SS500 Scintillation Probe
End window Gamma scintillation probe. A very sensitive end window scintillation probe designed to provide a low cost gamma monitor for energies of 50 keV upwards. It has a 25.4 x 25.4 mm NaI(Tl) crystal.
