PM1703GNA-II models are gamma-neutron PRDs equipped with a high-sensitive scintillator for measurement of the personal dose rate up to 300 µSv/h. PM1703-II series of personal radiation detectors (PRDs) are extremely sensitive and robust devices that detect and locate even trace amounts of radioactive materials. Equipped with a clip for multiple wearing options and easy to operate even for non-specialists, PRDs became the perfect fit as Radiation Pagers for public security agencies, including border control, rescue teams, police and anti-terrorist units that need to quickly search for radioactive materials in public places.
