Gamma detector PM1703MO-II BT

gamma radiationscintillationsemiconductor

Upgraded PRD PM1703xx-II Series have improved CsI(Tl) detector characteristics and fully comply with ANSI N42.32-2016. The extended measurement range is enabled by the installed new CsI(Tl) detector with a semiconductor photomultiplier (SiPM). * Instruments of PM1703xx-II Series were successfully tested in ORNL. PM1703MO-II BT has two built in detectors (CsI(Tl) and Geiger counter) and such competitive features as improved search algorithm and NORM supress function, extended DE and DER measurenet ranges, high sensitivity, compact size, user-friendly interface, low-energy operation, waterproof and shockproof case. Instrument is intended for everyday and/or emergency use by firefighters, military, police, and other first responding communities. Operation Principle The instrument has increased sensitivity due to two built in detectors: the highly sensitive CsI (Tl) scintillation detector for a fast response and location of radioactive sources, as well as energy compensated Geiger-Muller detector for high dose rate range and accurate measurement. The suppress NORM algorithm allows excluding alarm signal when the natural gamma background value increases and Naturally Occurring Radioactive Materials (NORM) are detected. The instrument displays the current level of gamma radiation background in numerical range from 0 to 9, that simplifies visualization of the radiation dose rate for the user. All the operations history is stored in the instrument non-volatile memory, protecting the data even when the battery is removed. The stored data can also be transferred to the personal computer via USB interface.
