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 740 pulse/s pulse rate from the Geiger-Muller counter.
Beta-particles flux density is about 4510
gamma background is not increased.
The sound symbol (4) means that audio signaling of registered gamma
quanta and beta-particles is on. If signaling is on, this symbol is displayed
on the LCD, and each registered gamma quantum or beta-particle is
followed by a short audio and/or vibration signal, which depends on the
chosen alarm type.
Audio signaling of registered gamma quanta and beta-particles is
switched on and off in the submode of alarm threshold level programming.
Surface beta-particles flux density is measured in a similar way to
photon-ionizing radiation DER measurement. As soon as the measurement
is started the LCD of the dosimeter begins to display the measurement
results and the statistical error values that correspond to these results. In the
process of measurement the statistical error of each next measurement result
becomes smaller, and in some time it reaches the specified statistical error.
