Advanced radiation survey meter system

January 2007 Analytical Instrumentation & Environmental Monitoring

Thermo Electron's FH 40 G multipurpose survey meter has a built-in, wide range, proportional detector measuring dose rates from 10 nSv/h to 1S v/h. The unit has dual channel capabilities for simultaneous measurement with an optional external detector. Up to 40 different external detectors are available for connection to the FH 40 G.

The FH 40 G, with only four keys, is easy to operate despite its multifunction capabilities. Desired functions can be activated or cancelled using an optional Windows-based operating program resulting in the FH 40 G corresponding precisely with the measurement task and reducing operator errors. Stored measured values can be accessed any time and displayed on the meter. For further processing and archiving purposes it is possible to transfer the data to a PC via the FH 40 G interface. Alarms levels are settable for both local and remote detectors including mixed radiation fields, ie, gamma and neutron.

When using the FH 40 G teleprobe as an external detector, remote locations may be investigated and personal safety of the operator is monitored locally. For special measuring tasks, the wide range dose detector at the tip of the telescope can be replaced by a high sensitivity scintillation detector or by a lightweight neutron sniffer.

Thermo Electron Corporation is represented locally by OEN Enterprises.

Keeping an eye on invisible radiation
Omniflex Remote Monitoring Specialists Analytical Instrumentation & Environmental Monitoring
At its peak in 1994, the energy generation capacity of the UK’s nuclear power stations was 12,7 GW across 16 plants. In 2024, the capacity has fallen to around 5 GW, and the number of stations is down to nine. However, this is far from the end of the story as spent nuclear fuel remains radioactive for centuries, and requires rigorous safety processes to safeguard against leaks.
