Operation Principle
PRDs are equipped with CsI (Tl) and 3He detectors for detection of gamma and neutron radiation sources. PM1401GNM detectors perform the following functions: detection of gamma and neutron radiation sources, even if they are shielded; warning the user about radioactive hazard with audible, visual and vibrating alarms; recording and storage of data (up to 1000 events) in non-volatile memory; data transfer to a PC via IR channel for processing and analysis. For work in difficult-to-access areas telescopic extension tube is provided.
Application
PM1401GNM detectors are recommended for first responders, emergency teams, police, customs officers and border patrol, hazmat teams, security guards
