1.2.2 The dosimeter displays the statistical error value of measurement
result of photon-ionizing radiation DER and surface beta-particles flux
density.
1.2.3 The dosimeter measures photon-ionizing radiation DER and
surface beta-particles flux density until the specified statistical error is
gained.
1.2.3.1 The specified statistical error can be programmed by the user
or automatically determined by the dosimeter depending on the radiation
intensity.

13
1.2.4 For fast evaluation of photon-ionizing radiation DER and surface
beta-particles flux density the dosimeter provides a ten-segment indicator of
instantaneous value. The information is updated on the indicator of
instantaneous value each 500 ms.
1.2.5Threshold alarm system with three independent threshold levels
is realized in the dosimeter:
-photon-ionizing radiation DER;
-photon-ionizing radiation DE;
-surface beta-particles flux density.
1.2.5.1 Threshold level values of photon-ionizing radiation DER in the
range of 0 to 9999 µSv/h with discreteness of 0.01 µSv/h are programmed
in the dosimeter.
1.2.5.2 Threshold level values of photon-ionizing radiation DE in the
range of 0 to 9999 mSv with discreteness of 0.001 mSv are programmed in
the dosimeter.

14
1.2.5.3 Threshold level values of surface beta-particles flux density in
the range of 0 to 9999·103part./(cm2·min) with discreteness of
0.01103part./(cm2·min) are programmed in the dosimeter.
1.2.5.4 The programmed values of the threshold levels are saved in the
nonvolatile memory of the dosimeter, and are not changed when the
dosimeter is turned on/off or the batteries are replaced.
1.2.6The dosimeter provides four alarm types about the programmed
threshold levels exceeding: audio, vibration, vibration and audio, and visual.
1.2.6.1 The dosimeter sends a two-tone audio signal and/or an
intermittent vibration signal when the programmed threshold levels are
exceeded.
1.2.6.2 If the programmed threshold levels are exceeded the dosimeter
provides visual alarm in the form of a measurement result blinking on the
liquid crystal display, and periodic and subsequent (from left to right)
highlighting of segments of a sound symbol (4) according to Figure 3.
1.2.7The dosimeter sends a short one-tone audio signal and/or a short
vibration signal if gamma quantum or beta-particle gets to the detector.

15
1.2.8The dosimeter stores up to 1200 measurement results of photon-
ionizing radiation DER or surface beta-particles flux density in its
nonvolatile memory. For more convenient identification every measurement
result is stored along with a three-digit number of measurement object, as
well as with time and date of measurement. Time and date of measurement
is received from the dosimeter’s clock, while the object number is entered
by the user during saving.
1.2.9 The dosimeter sends the measurement results,which have been saved
in the nonvolatile memory,to the personal computer (hereinafter called the PC)
through Bluetooth radio channel. There is also a possibility to view this
information on the liquid crystal display of the dosimeter (hereinafter called the
LCD).
1.2.10 The dosimeter has the mode of clock when the current time in
hours and minutes, as well as the current date, month and year are displayed
on the LCD.
1.2.11 The dosimeter has the mode of alarm clock.

16
1.2.12 The dosimeter provides the possibility to work in the mode of
intelligent detecting unit (hereinafter called the IDU). In this mode the
dosimeter sends to the PC via the Bluetooth radio channel:
-current measurement results of photon-ionizing radiation DER or surface
beta-particles flux density;
-current value of accumulated photon-ionizing radiation DE, as well as
DE accumulation time;
-current value of supply voltage, and receives from the PC the commands
to change the measurement modes and to synchronize the time based on the
PC clock.
1.2.13 The dosimeter provides indication of low battery status.
1.2.14 The dosimeter performs measurements under the following
conditions:
-temperature from –20 to + 50 oC;
-relative humidity up to (95±3) % at + 35 oC temperature;
-atmospheric pressure from 84 to 106.7 kPa.

17
1.2.15 The dosimeter is resistant to the following external factors:
-high frequency sinusoidal vibrations (with crossover frequency from
57 to 62 Hz) in the range of 10 to 55 Hz, 0.15 mm bias for frequency lower
than the crossover frequency;
-shocks with a shock pulse duration of 5 ms, a total number of shocks
1000±10 and maximum acceleration of 100 m/s2;
-shocks in shipping container with an acceleration of 98 m/s2, with a
shock pulse duration of 16 ms (number of shocks - 1000±10 in each
direction), or equivalent shake tests;
-exposure in shipping container to ambient air temperature from -25
to + 55 oC and relative humidity up to (95±3) % at + 35 oC;
-photon-ionizing radiation with exposure dose rate that corresponds to
ambient DER up to 1.0 Sv/h during 5 minutes.
