The small but sensitive radioactivity detectors below can be easily carried in the hand and will fit into a pocket but they need separate power, software and display, however, all they need is a laptop or tablet running our gamma spectroscopy software. The laptop or tablet (running Windows 10) provides the power, software and display, plus the radiation detector units are small enough to carry in a pocket and can survive life in the field.
GR1 CZT gamma-ray radioisotope identifier
The Kromek GR is the radioactivity detector unit mounted inside the probe of the Raymon10. It is one of our most popular gamma detection products because it is one of the world’s smallest, lightest, most sensitive, room temperature gamma radioisotope identifier. Built into the unit is a preamplifier, shaping amplifier, baseline restorer, pulse height digitizer, and HV – all in a metal case about the size of a lipstick. The GR1 contains a one-centimetre cube of CZT.
SIGMA scintillation gamma detectors
Sometimes you need a scintillation detector rather than CZT. The SIGMA unit uses CsI(Tl) thallium activated caesium iodide scintillator crystal.
SIGMA has two models, both can fit in a pocket.
- SIGMA-25, scintillation crystal volume 16.4 centimetre cubed.
- SIGMA-50, scintillation crystal volume 32.8 centimetre cubed.
Perfect for taking out into the field, clients have used them on flying drones and ground rovers. SIGMA offers fast radiation detection in a small package.
TN15 neutron detector
The power of a much larger, much costlier detector that can fit in the palm of your hand (equivalent to 100mm x 13mm Ø 3He at 4 atmospheres). The TN15 surpasses the performance of a 100mm long 13mm3 He tube at 4 atmospheres without the need for cooling. The TN15 neutron detector operates at room temperature and does not have all the associated running costs or problems of helium cooled systems.
