RadEye™ G Series Personal Dose Rate Meters

Manufacturer – Thermo Fisher Scientific

Description: Thermo Scientific RadEye™ G Series personal dose‑rate meters are lightweight handheld devices that provide first responders with quick, reliable gamma and dose‑rate measurements — even detecting very low gamma energies and showing the smallest changes in radiation rates immediately.
They feature a rugged, shock‑resistant design with menu‑driven interface, large back‑lit display, and options for intrinsically safe versions suitable for potentially explosive atmospheres.

Technical Specifications:
Detector type: energy‑compensated Geiger‑Mueller (GM) tube
Dimensions (L × W × H): 3.78 × 1.25 × 2.4 in. (9.6 × 3.1 × 6.1 cm)
Weight: 0.18 kg (0.41 lb)
Battery type & life: 2 × AAA batteries, up to ~900 hours operation
Energy range: 45 keV to 1.3 MeV (some models up to 3 MeV)
Measurement range example (G‑10 model): 0.5 µSv/h to 100 mSv/h (50 µrem/h to 10 rem/h) with overrange threshold up to 10 Sv/h
Protection degree: IP 65 (per EN 60529)
Count rate sensitivity example: for Cs‑137 (66 keV): 1.7 cps per µSv/h
Key Features:
• High sensitivity to low‑energy gamma radiation, enabling detection of small changes in dose‑rate.
• Menu‑driven interface with a large, clear back‑lit display for error‑free readings.
• Rugged, shock‑resistant design, built for harsh environments.
• Bright LED (and in some models audible/vibrating alarms) for visibility in smoke/darkness and challenging conditions.
• Versions certified for intrinsically safe use in potentially explosive atmospheres (ATEX‑certified).
• Long battery life (≈900 hours) and compact size/weight for ease of use and portability.
• Optional Windows‑based PC software and reader device for data analysis
Applications: Ideal for radiation safety, emergency response, hazmat teams, and monitoring gamma dose‑rates in nuclear/radiological incidents or potentially explosive environments.
