1.2.3 The radiometer provides for automatic subtraction of gamma- and beta-
components of radiation while measuring alpha radiation parameters.
1.2.4 The radiometer provides for analogue indicator of instantaneous radiation
intensity being measured. Time of information update is 500 ms.
1.2.5 The radiometer allows programming the values of alarm threshold levels
for each radiation parameter being measured.
1.2.5.1 The values of threshold levels of photon-ionizing radiation DER are
programmed in the range from 0 mSv/h to 99.9 mSv/h with a resolution of
0.01 μSv/h.
1.2.5.2 The values of threshold levels of surface beta-particles flux density are
programmed in the range from 0 part./(cm
a resolution of 0.01·10
1.2.5.3 The values of threshold levels of surface activity of beta-emitting
radionuclides are programmed in the range from 0 Bq/cm
a resolution of 0.01 Bq/cm
