What difference does the energy response of a radiation survey meter make to your workflow and the accuracy and efficiency of your readings? Glenmed Professional Healthcare Solutions answers this question with reference to the Fluke Biomedical’s RaySafe 452 radiation survey meter.

No Manual Correction Factors

When you use a radiation survey meter with a flat energy response, you don’t have to worry about manual correction factors, i.e. you don’t have to change settings on the device for different environments. This means that you decrease the risk of underestimating doses to patients and staff. You also decrease the risk of human error and save on the time you spend analysing the data.

How does a radiation survey meter with flat energy response differ from other, similar devices on the market?

A Varying Energy Response Can Lead to Inaccurate Readings

Survey meters that are not designed for flat energy response tend to over-respond or under-respond in some energy ranges. Meters with pressurised ionisation chambers under-respond below 50 keV. These inaccurate readings mean that you can regularly underestimate or overestimate radiation levels, and thus place staff and patients at risk of exposure.

How Does The Raysafe 452 Have a Flat Energy Response?

Although the Geiger-Müller pancake detector and the semiconductor diodes actually do have varying energy responses on their own, they are energy compensated internally. There are difference filters that are used to balance out the energies detected by the device. The filters boost some energies and attenuate others to produce a flat energy response across a wide range of energies.
