1.2.3 The radiometer measures photon-ionizing radiation DER and surface
beta-particles flux density until the specified statistical error is gained.
1.2.3.1 The specified statistical error can be programmed by the user or
automatically determined by the radiometer depending on the radiation intensity.
1.2.4 For fast of photon-ionizing radiation DER and surface beta-particles flux
density the radiometer provides a twelve-segment indicator of instantaneous value.
The information is updated on the indicator of instantaneous value each 500 ms.
1.2.5 Threshold alarm system with two independent threshold levels is realized
in the radiometer:
- photon-ionizing radiation DER;
- surface beta-particles flux density.
1.2.5.1 Threshold level values of photon-ionizing radiation DER are
programmed in the range of 0 to 999,9 µSv/h with discreteness of 0.01 µSv/h.
1.2.5.2 Threshold level values of surface beta-particles flux density are
programmed in the range of 0 to 9999·10
