Ermes MicroDose Dosimeter

Maintenance in Nuclear Power FacilitiesMicro-dose Dosimeter by Ermes

This MicroDose dosimeter is specifically designed to memorize dose, temperature and vibration measurements in long term exposure of non-accessible, high radiation areas. The convenient MicroDose dosimeter does not require a power cable. It is only necessary to attach the device in areas that need to be monitored. The autonomous measurements made by MicroDose allow measurements in rugged areas close to the reactor facilities, such as valves and pipes.


• Gamma dose, temperature, and vibration measurements (options)
• Entirely autonomous
• No need for power cable
• No need for measurement transmission cable
• Measurement controlled by an embedded hardened microprocessor
• Data recorded on an embedded hardened memory
• Autonomous system entirely hardened up to 3 kGy or 8 kGy
• Power autonomy up to 24 months


• Identification of vulnerable facilities for an optimized maintenance in nuclear plants
• Mapping of cumulated dose in exposed zones
• Area characterization before dismantling operation
