Personal Radiation Detector PM1703GNA-II

Category: Gamma-Neutron PRDs

PRD PM1703GNA-II 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).

Operation Principle

As well as previous well-known modifications of PRD PM1703 Series, PM1703GNA-II continuously monitors the environment for radiation, measures personal Dose Equivalent Rate (DER) of gamma raiation and alerts the user with 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 2000 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.

Supress NORM algorithm

This algorithm allows excluding alarm signal when the natural gamma background value increases and Naturally Occurring Radioactive Materials (NORM) are detected. If NORM are detected - green indication light is given. In the case the other radionuclides types (IND, NUC, MED) are detected, red indication light and sound alarm are activate

Modifications

  • PM1703GNA-II - (basic model) is designed to detect, search, and localize gamma and neutron radioactive sources by their external gamma and neutron radiation, as well as to measure personal Dose Equivalent Rate (DER) of gamma radiation;
  • PM1703GNA–II BT - additionally to the functions of the basic model, is equipped with Bluetooth radio channel that enables the function of smartphones communication;
  • PM1703GNA–II MBT differs from the basic model by extended range of DER measurement, availability of personal Dose Equivalent (DE) measurement and Bluetooth.

Options

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.

Application

Instrument is designed for everyday use in both indoor and outdoor environments by first responding communities: emergency services, customs and border patrol, police.

Standards Compliance

Storing data format is designed to meet ANSI N42.42.

Complies with ITRAP/IAEA requirements, ANSI 42.32-2016 and IEC
