Range of registered energies of neutron radiation from 0.25 eV to 15 MeV
Battery operating time up to 45 days
Quick response to the dose rate changes
Possibility of remote, real-time control of personnel dose exposure
Application
Nuclear power plants and fuel cycle facilities
Oil, gas and mining industry
Medical institutions
Radiological and isotope laboratories
Processing and transportation of radioactive materials
RF interface
Dosimeter is equipped with a wireless data exchange module which allows automated registration of the personnel in exposure monitoring system and issuing personal radiological work permits; simultaneous transmission of measurement results to the personnel exposure monitoring system from several dosimeters; remote control of the access, movement, location and duty hours of personnel in the restricted areas under issued radiological work permits; integration to automatic access control systems.
The reader may be located autonomously in different zones of the controlled areas and simultaneously receive data from several dosimeters in the acquisition range and also may be built in different gadgets like turn gates, info desks, etc.
