  • Ideal for use with reactors, spent fuel and glass waste transport, reprocessing and plutonium finishing, mixed oxide and neutron source manufacturing, nuclear research, and medical facilities
  • Advanced radiological performance: 25 keV to 10MeV (photon); thermal to 15MeV (neutron)
  • Multiple diode detectors with converters and energy compensation shields
  • Direct display of Hp(10) for neutron and for photons
  • Outstanding immunity to electromagnetic interference
  • Stores 500 dose data point for g and neutron dose with date and time; 10-year data retention without battery
  • Lightweight yet rugged case withstands 5ft. (1.5m) drop onto concrete on each surface
  • Dose display and storage: 0μSv to > 16Sv, autoranging
  • Resolution for display: 1μSv (< 10mSv/1rem) ( γ, and neutron under best conditions)
  • Resolution for storage: 1/64μSv (∽1.5μrem) (γ), 1μSv for neutron dose under best conditions
  • Dose rate display: 0μSv/h to > 4Sv/h (400rem/h), autoranging, variable resolution
  • Communications: IR interface, < 1m range (39in.)
  • Display and enabled functions controlled by button on front face of EPD (button recessed and sealed)
  • Angular response: Hp(10) (γ) ± 20% up to ± 75° Cs137; Hp(10) (n) ± 30% up to ± 60°
  • AmBe
  • Protection rating: IP55 (protection against dust ingress and low pressure jets of water from all directions)
  • Vibration: IEC 1283 (2g, 15 min.,10-33Hz)
