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.
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.
PM1703GNA–II MBT model is a gamma-neutron PRD/dosimeter equipped with a high-sensitive scintillator and a Geiger-Mueller counter for extended measurement of the personal dose rate up to 200 mSv/h and personal dose up to 10 Sv. This model also has a Bluetooth module that enables communication with smartphones for advanced operation via the free Polismart® App.
Operation Principle
PM1703GNA-II MBT is a gamma-neutron PRD/dosimeter equipped with a high-sensitive scintillator and a Geiger-Mueller counter for extended measurement of the personal dose rate up to 200 mSv/h and personal dose up to 10 Sv. While ensuring high-performance detection for any scenario, PM1703-II PRD provides confidence in personal safety by continuously monitoring the measured dose equivalent rate and alerting the user with visual, audible and vibration alarms when the pre-set radiation thresholds are exceeded.
Operating history is stored in the instrument‘s non-volatile memory (up to 2000 data points), protecting the data even when the battery is removed. The stored data can also be transferred to a PC via USB. Storing data format is designed to meet the ANSI N42.42.
The PRD features a dedicated operation mode "Mode 0...9" specifically designed for monitoring gamma radiation dose rate within a numerical range. This mode is particularly user-friendly, making it easier for non-professionals to understand and navigate.
Polimaster PRDs offer a significant advantage with their NORM suppression algorithm. This algorithm differentiates alarm signals when there is an increase in natural gamma background values and detection of Naturally Occurring Radioactive Materials (NORM). When NORMs are detected, a green indication light is displayed. However, if other radionuclide types (IND, NUC, MED) are detected, a red indication light and sound alarm are activated. This feature ensures clear and distinct indications based on the specific type of radiation detected.
