As soon as the measurement is started the surface beta-particles flux density
measurement results (7) and the statistical error values (1) that correspond to these
results begin to be formed on the LCD.
If the flux density measurement results exceed the alarm threshold level (10),
the radiometer sends a two-tone audio signal and starts blinking with the “ALARM”
LED (11). Measurement results start blinking on the LCD of the radiometer.
Periodic and gradual (from left to right) highlighting of the sound symbol segments
(4) serves as an indication of the threshold level exceeding as well.
The twelve-segment indicator of instantaneous value (3) is used for fast
evaluation of intensity of photon-ionizing radiation and beta-particles flux. The
integration time during measurement of the instantaneous intensity value and the
time of information update on the instantaneous value indicator are equal to 500 ms.
The instantaneous intensity value is displayed in pseudo-logarithmic scale. The
first segment of the indicator becomes highlighted when the intensity corresponds to
2 pulse/s pulse rate from the gamma and beta radiation detector. The greater the
intensity becomes the more scale segments start to be highlighted from left to right.
The scale becomes fully highlighted when the intensity equals to 3400 pulse/s pulse
