PRD PM1703GNA-II (PM1703®) is a brand-new personal gamma-neutron radiation detector, which has such competitive features as compact size, user-friendly interface, low-energy operation, waterproof and shockproof case combined with extremely high sensitivity.
Instrument continuously monitors the environment for radiation and alerts the user with a visual, audio and/or vibrating alarm if a radiation source is detected or any of preset radiation thresholds are exceeded.
The instrument can be used in both indoor and outdoor environments for detection and localization of gamma and neutron radiation sources and measurement of dose equivalent rate (DER).
As well as previous well-known modifications of PRD PM1703 series (PM1703®) , PM1703GNA-II (PM1703®) continuously monitors the environment for radiation, evaluates dose equivalent rate (DER) and alerts the user with a visual, audio and/or vibrating alarm if a radiation source is detected. The readings of the instrument are displayed in counts per second for both neutron and gamma detectors and the search algorithm based on background calibration is used. The Instrument has “Mode 0…9” , which is designed to display the current level of gamma radiation background in the form of digits from 0 to 9. Instrument is equipped with 6LiF/ZnS-screen based neutron detector, which complies with ANSI N42.32-2016 requirements.
All operations history is stored in the instrument non-volatile memory (up to 1000 data points), protecting the data even when the battery is removed. The stored data can also be transferred to the PC via USB interface. Storing data format is designed to meet ANSI N42.42.
PM1703GNA-II is manufactured in two versions:
– has a neutron detector based on scintillator 6LiI(Eu) and fully complies with ANSI N42.32-2006 requirements
– has a 6LiF/ZnS-screen based neutron detector and complies with ANSI N42.32-2016 requirements
Optionally PM1703GNA-II can be equipped with holster that provides additional protection for the instrument from weather, dust and occasional drops. It can be also fixed on the waist belt using belt loop.
Instrument is designed for everyday use in both indoor and outdoor environments by first responding communities: emergency services, customs and border patrol, police.
Storing data format is designed to meet ANSI N42.42.
Complies with ITRAP/IAEA requirements, ANSI 42.32-2016 and IEC
