Polimaster's gamma-neutron personal radiation detectors PM1703GN and PM1703GNA are designed to detect the slightest amounts of the gamma and neutron radiation emitting materials. The instruments are equipped with a CsI(Tl) (for gamma detection) and a LiI(Eu) (for neutron detection) scintillation detectors to alert the user that the radiation levels have exceeded the preset threshold values.
