Pocket personal gamma detector/pager (Geiger-based) alerting the wearer to trace sources
The PM1703MA-II is a gamma-only Personal Radiation Detector (PRD) equipped with a high-sensitive CsI(Tl) SiPM scintillator for measurement of personal dose rate up to 300 µSv/h. It features ANSI N42.32-2016 and IEC 62401:2017 compliance, NORM-suppression algorithm for differentiating natural vs. man-made radiation, operation in extreme temperatures from –40 °C to 50 °C, long-life alkaline or rechargeable battery for 1000 hours, shockproof hermetic IP65 case, audible/visual/vibration alarms, and optional Bluetooth communication. Designed for customs, border control, HAZMAT teams, counter-terrorism, and first responders.
