Portable radiation monitor "GRANAT"
Design
The portable radiation monitor “GRANAT” is made in the form of a portable, dust- and moisture-proof sealed plastic case, in which gamma and neutron radiation detection units, electronic components, a built-in GPS module, a battery and an internal control panel are installed, which provides access to all functions of the monitor when the case is open.
In the area of the handle on the outside of the case there is a small-sized control and display panel that allows you to control the main functions of the device without access to the inside of the case.
The internal equipment of the monitor is placed in such a way that there is no direct contact with the external casing, which ensures increased resistance of the product to external mechanical influences.
To ensure access control to the internal space of the monitor, a combination padlock included in the delivery package can be used.
The device is equipped with a light alarm for gamma and neutron radiation registration (indicators of different colors are used to distinguish between alarms in the gamma and neutron channels).
Operating and access mode
- Controlling the device from an external panel (Online mode)
- Ability to snap to background
- Continuous search for sources of gamma and neutron radiation
- Классификация обнаруженных радионуклидов по типам (специальные, индустриальные, медицинские, природные) по команде оператора
- Recording spectra
- Controlling the device from the internal panel (Expert mode)
When the case is open, the operator has access to all monitor functions through a user interface implemented using five buttons and a graphic display on the internal panel. The display shows the results of search and measurement of dose rate in graphical and digital form, identification results - in the form of a list of detected radionuclides.
In addition to all the functions available in online mode, the following functions become available when operating the device in expert mode:
- Setting measurement parameters,
- View identification results,
- Work with spectra and library of radionuclides,
- Exchange data with a computer.
Peculiarities
- Search, localization and identification in real time
- In online mode, convenient one-handed operation using two buttons
- Automation of service and test procedures
- High resistance to external influences (IP67)
- Встроенная система самодиагностики без участия оператора
- Automatically adjusts energy calibration while charging battery
- Storage of spectra, measurement results and GPS data
- Wireless data exchange with a computer
