1.2.2 The radiometer provides for automatic subtraction of gamma-component
of radiation when measuring beta radiation parameters.

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.

programmed in the range from 0 mSv/h to 99.9 mSv/h with a resolution of
0.01 μSv/h.

volatile memory of the radiometer and remain unchanged when the radiometer is
turned on/off and its batteries are replaced.
1.2.6 The radiometer alarms about exceeding of the programmed threshold
levels with a two-tone sound signal and a red flashing ALARM LED. In this case,
the measurement result blinks on the liquid crystal display (hereinafter referred to
