ECOTEST SPECTRA MKS-11GN Operating Manual page 11

1.2.9 The false alarm rate for photon-ionizing radiation and
neutron rays is not more than 1 per 10 hours of operation in a stable
background environment and at the following values of threshold
levels:
- Search – 5;
- Safety – 1 µSv/h;
- Neutron – 5.
1.2.10 The device does not give false signals about the presence
of neutron radiation when exposed to photon-ionizing radiation from
60 137
Со or Cs source at DER value of up to 100 µSv/h.
1.2.11 The device can automatically record event log files in the
nonvolatile memory, namely:
- Switch the dosimeter on;
- Switch the dosimeter off;
- Search threshold level being exceeded;
- Safety threshold level being exceeded;
- Conditional threshold level being exceeded in the detector of
neutron radiation;
- Accumulated dose threshold level being exceeded;
- Save measurement by the user's command;
- Change settings by the administrator;
- Clear the device's flash memory;
- Identification results.
1.2.12 The nonvolatile memory stores up to 20,000 records of
registered event, as well as 250 full gamma spectra.
1.2.13 The device can identify the following gamma
radionuclides:
