Radiation Survey Meter
Benefits of a flat energy response in a radiation survey meter
How does the energy response of a radiation survey meter impact measurement results and work-flow? We sat down with Magnus Smith, Product Manager of the RaySafe 452 Radiation Survey Meter, to discuss some common questions on the topic.
I have read that the RaySafe 452 has a flat energy response and does not require correction factors. What does “a flat energy response” mean?
Does the RaySafe 452 need specific documentation to be transported by air?
No, you can ship the RaySafe 452 by air without extra paper work. Some survey meters, like the Fluke 451P and other similar instruments, are pressurized and classified as hazardous material.
The RaySafe 452 is not pressurized and is therefore not classified as hazardous material.
Can I use the RaySafe 452 for isotope identification?
No. The RaySafe 452 measures the mean photon energy of the complete spectrum, including scattered radiation, and is not able to quantify the energy of specific spectral peaks. The mean energy parameter is meant to be used more as a rough estimate for radiation protection purposes.
Do I need to calibrate my RaySafe 452?
We recommend a yearly calibration of the RaySafe 452 and offer service programs. The calibration date is printed on the lid(s). Note that the RaySafe 452 must be calibrated together with its specific lids.
My RaySafe 452 shows an error message when I try to measure contamination (without lid). Why?
If you see an error like this, you have an instrument model without the counter functionality. The model that can measure without lid is denoted RaySafe 452. An instrument with model RaySafe 452 Ambient and RaySafe 452 Air kerma requires a lid to measure. See the model name on the label of your instrument.

Can I use the RaySafe 452 for long-term measurements, like area monitoring?
Yes, the RaySafe 452 is suitable for long-term measurements.
