Continuously monitor your radiation exposure in any nuclear or radiological emergency. The Thermo Scientific™ RadEye™ G Series of personal radiation detectors provide first responders with quick, reliable gamma and dose rate measurements. These light-weight, handheld Geiger counters detect and measure very low gamma energies; even the smallest change in radiation rates are displayed immediately, while coincidentally occurring fluctuations are suppressed. For hazmat teams investigating potentially explosive atmospheres, intrinsically safe RadEye G models meet the latest ATEX standards.

RadEye G /G-10 instruments are used for gamma surveys from background up to personal safety levels.

  • Applications: High sensitivity to low energy gamma radiation in harsh environments.
  • Audible single pulse indication and finder mode.
  • Menu-driven with an intuitive, easy-to-use format.
  • Incorporates a large energy-compensated Geiger-Mueller tube for the precise dose rate measurement of gamma and X-ray radiation.
  • Intelligent ratemeter algorithm (ADF mode) ensures that even the smallest changes in dose rate are immediately detected, while, at the same time, random fluctuations are effectively suppressed.
  • Low-power-technology components and fully automated self-checks result in minimum maintenance.
  • Equipped with large clear graphic display and audible/visible/vibrating alarms; earphone-output for silent alarming.
  • Removable rubber sleeve for extra protection.
  • All essential functions are easily accessed by users wearing protective gloves.
  • Alarm LED can be seen while instrument is housed in belt holster; also features built-in vibrating alarm.
  • Earphone output for operation in loud environments.
  • Large graphic display with clear prefix and bar graph.
