1.2.2 The radiometer displays the statistical error value of measurement result
of photon-ionizing radiation DER and surface beta-particles flux density.

11
1.2.3 The radiometer 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 radiometer depending on the radiation intensity.
1.2.4 For fast of photon-ionizing radiation DER and surface beta-particles flux
density the radiometer provides a twelve-segment indicator of instantaneous value.
The information is updated on the indicator of instantaneous value each 500 ms.
1.2.5 Threshold alarm system with two independent threshold levels is realized
in the radiometer:
- photon-ionizing radiation DER;
- surface beta-particles flux density.
1.2.5.1 Threshold level values of photon-ionizing radiation DER are
programmed in the range of 0 to 999,9 µSv/h with discreteness of 0.01 µSv/h.
1.2.5.2 Threshold level values of surface beta-particles flux density are
programmed in the range of 0 to 9999·103part./(cm2·min) with discreteness of
0.01103part./(cm2·min).

12
1.2.5.3 The programmed values of the threshold levels are saved in the
nonvolatile memory of the radiometer, and are not changed when the radiometer is
turned on/off or the batteries are replaced.
1.2.6 The radiometer provides light and audio alarm about the programmed
threshold levels exceeding: a two-tone audio signal and a blinking red LED
“ALARM”.
1.2.6.1 The radiometer also provides visual alarm of the exceeded threshold
levels in the form of a measurement result that blinks on the LCD, and periodic and
gradual highlighting (from left to right) of the sound symbol segments (4) according
to Figure 3.
1.2.7 The radiometer sends a short one-tone audio signal if gamma quantum or
beta-particle gets to the detector.
1.2.8 The radiometer 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 radiometer’s
clock, while the object number is entered by the user during saving.

13
1.2.9 The radiometer 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 radiometer (hereinafter called the LCD).
1.2.10 The radiometer 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 radiometer has the mode of alarm clock.
1.2.12 The radiometer provides the possibility to work in the mode of
intelligent detecting unit (hereinafter called the IDU). In this mode the radiometer
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 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 radiometer provides indication of low battery status.

14
1.2.14 The radiometer 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.
1.2.15 The radiometer 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 0.1 Sv/h during 5 minutes.

1.4 Design and principle of operation
1.4.1 Design of the radiometer
The radiometer (according to Figure 1) is designed as a rectangular
parallelepiped rounded on each side. The plastic damp and dustproof body of the
radiometer (ingress protection rating IP54) consists of two parts –upper (1) and
lower (2) covers. The LCD (3), “ALARM” light-emitting diode (4) and two key of
control MODE (5) and THRESHOLD (6) are located on the panel of the upper cover.
The printed-circuit board with the electric circuit of the device is screwed with four
screws to the upper cover of the radiometer. All inscriptions of the upper cover are
serigraphy applied.
