1.2.2 The dosimeter ensures automatic subtraction of gamma radiation
component during measurement of beta radiation parameters.
1.2.3 The dosimeter allows storing up to 1500 measurement results in the non-
volatile memory. For easier identification, each measurement result is recorded with
information about measurement time, geographical coordinates of measurement and
a reference three-digit number of measurement object, which is entered during
recording.
1.2.4 The dosimeter provides for automatic recording of photon-ionizing
radiation DE accumulation history in its nonvolatile memory. The nonvolatile
memory capacity ensures saving up to 2200 DE values. Saving frequency depends
on DER and falls within 10 to 1 minute. DE is saved additionally when you turn the
dosimeter on and off.
1.2.5 The dosimeter beeps at detection of every gamma quantum, alpha- or
beta-particle.
1.2.6 The dosimeter allows viewing measurement results earlier stored in the
nonvolatile memory on its own LCD, and PC communications via the
infrared port.
1.2.7 The dosimeter has an analog indicator of measured radiation intensity.
1.2.8 The dosimeter allows programming the values of threshold alarm for
each measured radiation parameter.
1.2.9 The dosimeter sends a light and a sound signal when the programmed
threshold levels are exceeded.

1.2.10 The dosimeter is powered from lithium-ion battery of 26650 size with
an integrated protection board against overcharging, prevention of discharge and
short-circuit. Battery rated voltage –3.7 V, capacity –4000 mAh.
1.2.11 The dosimeter warns of the battery discharge.
1.2.12 The battery can be charged from:
- AC mains from of 220V voltage, frequency of 50 Hz;
- vehicle network with DC voltage from 9 V to 32 V.
What is more, the battery can be charged from the solar panel.
1.2.13 The dosimeter ensures measurements if influenced by:
- ambient air temperature from –30 to + 55оС;
-relative humidity up to 95 % at 35 оС temperature, non-condensing;
Note. For operation in the temperature range from minus 21°C to minus 30°C, the
dosimeter must be switched on at a temperature not lower than minus 20°C, or be powered
by an external power source (power supply unit 220V/ =12V or avehicle battery).
- atmospheric pressureof 84 kPa up to 106.7 kPa;
1.2.14.ThedosimeterisproofagainstN1groupsinusoidalvibrationswithafrequency
from 10 Hzto 55 Hz, with an offsetamplitude for afrequencylower than0.15 mm transition
frequency.
1.2.14 The dosimeter remains operable after the influence of the following
external factors:
- maximum low temperature –40оС;
- maximum high temperature +60 оС;
- photon-ionizing radiation with DER of 100 Sv/hour during a 5-minute
exposure of the control unit, and 100 Sv/hour during a 50-minute exposure of the BG
probe, 100 Sv/hour during a 10-minute exposure of the ABG probe.
