Measurement of basic characteristics of scintillation-type radiation survey meters with multi-pixel photon counter

The basic characteristics of three low-cost radiation survey meters using multi-pixel photon counters (MPPC), the C12137, T-GMK2-S, and iMetry, were measured. The linearity of the dose rate was confirmed over the full range of each instrument. All the survey meters could obtain gamma-ray energy spec...

Description
Summary:The basic characteristics of three low-cost radiation survey meters using multi-pixel photon counters (MPPC), the C12137, T-GMK2-S, and iMetry, were measured. The linearity of the dose rate was confirmed over the full range of each instrument. All the survey meters could obtain gamma-ray energy spectra, with an accuracy within ± 30% of the theoretical value. These survey meters are therefore applicable for radiation management. •The basic characteristics of three survey meters using MPPC detectors were measured.•All meters showed more than three orders of magnitude of dose rate linearity.•All meters could measure radiation energy spectra.•The energy characteristic sensitivities were within ± 20% of the theoretical value.
