1.3 Radiation registration method
1.3.1 Radiation detector
Terminal Geiger-Muller counter is used in the Indicator as radiation detector. The flux of
photons of gamma and X-ray radiation, flux of alpha particles and beta particles are converted
by the detector into the sequence of electrical signals. These signals are formed by duration
and amplitude, and then are delivered to microprocessor registration circuit which provides
automatic processing and displaying the measurement results.
1.3.2 Displaying of measuring data on the display
Depending on the selected measurement mode, the display shows:
averaged numerical value of the dose or dose rate with indication of units of
measurement;
averaged numerical value of beta-particles flux density with indication of units of
measurement;
averaged numerical value of alpha particles flux density with indication of units of
measurement;
time from the beginning of the current measurement;
graphic representation of measured value and user defined alarm thresholds;
current statistical measurement error in confidence interval of 0.95;
current alarm level;
current time or date;
prompts, if measurement technique requires any additional actions by the user.

6
1.3.3 Signal of registration of particles
The indicator makes sound signals (clicks) on registration of photons, or particles of ionizing
radiation. The higher is the level of radiation, the higher is the average frequency of clicks.
These signals can be disabled using the settings of the Indicator.
1.3.4 Alarm signals
When any alarm threshold is exceeded the Indicator makes a corresponding sound. Alarm
signals can be disabled using the settings of the Indicator.

detector window is covered with the filter without metal.
1.5 Indicator operating modes
Setting of the Indicator is done in setting mode. To evaluate the level of radiation, automatic or
manual measurements are used.
Measurements in automatic modes will start immediately after their activation in the main
menu of setting modes. Measurements are made continuously and are completed with the
activation of another measurement mode. Automatic modes are:
Mode for constant control of gamma-radiation (hereinafter referred to as GAMMA
mode);
radiation sources search mode (hereinafter referred to as SEARCH Mode).
GAMMA is the main mode. The indicator switches to this mode after switching on.
Measurements in manual modes start only after the user presses the corresponding button,
they are stopped either automatically or upon pressing of a button. Manual modes are:
Mode of evaluation of beta particles flux density (hereinafter referred to as BETA mode)
–only for RadiaScan-701;
Mode of evaluation of alpha particles flux density (hereinafter referred to as ALPHA
mode) –only for RadiaScan-701;
Radiation sources DETECTION mode (hereinafter referred to as the DETECTION mode).
1.5.1 GAMMA mode
It is intended for assessment of cumulative dose and dose rate of the current level of gamma
and X-ray radiation.
This is the basic mode of operation. It is activated immediately after the Indicator switching-on.
The graphical interface of the mode, setting of parameters and order of use are described in
chapters 1.7.1, 2.16. и3.7 correspondingly.

8
1.5.2 SEARCH mode
The mode is used for search for sources of radiation on the area by moving the Indicator above
the surface being examined and for defining areas with the highest readings. This mode is much
more responsive to changes in radiation background compared to GAMMA mode, but due to
significant decrease in the accuracy of readings.
The graphical interface of the mode, setting of parameters and order of use are described in
chapters 1.7.2, 2.18 и3.8 correspondingly.
1.5.3 BETA mode
The mode is intended for assessment of beta-particles flux density by two measurements.
Measurements are taken over long intervals of time (from several minutes to several hundred
minutes). Duration of one measurement can be limited explicitly or implicitly by specifying the
required level of statistical error.
The graphical interface of the mode, setting of parameters and order of use are described in
chapters 1.7.3, 2.19 and 3.9 correspondingly.
1.5.4 ALPHA mode
The mode is intended for assessment of alpha particles flux density by two measurements.
Measurements are taken over long intervals of time (from several minutes to several hundred
minutes). Duration of one measurement can be limited explicitly or implicitly by specifying the
required level of statistical error.
The graphical interface of the mode, setting of parameters and order of use are described in
chapters 1.7.4, 2.20 and 3.10 correspondingly.
1.5.5 DETECTION mode
The mode is used to detect the fact of radioactive contamination of the surfaces of objects,
food products, and other objects, by two measurements. Measurements are taken over long
intervals of time (from several minutes to several hundred minutes). Duration of the
measurement can be limited explicitly or implicitly by specifying the required level of statistical
error.
The graphical interface of the mode, setting of parameters and order of use are described in
chapters 1.7.5, 2.21 и3.11 correspondingly.
1.6 Displaying and alarm
To display the special statuses of the Indicator and specific events recorded by it, LEDs, buzzer
and display are used. With the help of these means the Indicator gives the following signals to
the user:
1.6.1 Signal of LED explicit power on/off
In this case, the green LED lights up for 2 seconds once, and goes out.
1.6.2 Signal of LED passive state at presence of power supply at USB-slot
Green LED generates short pulses of minimum brightness with the frequency of 1 pulse per
4 seconds. In this state, the Indicator does not perform any measurements and is waiting for
explicit or implicit power-up.
1.6.3 Signal of LED implicit switching on
If the Indicator is off, then for conduct of measurement by schedule it may switch on implicitly,
and green LED generates short pulses with minimum brightness at the frequency of 2 pulses
per second.

9
1.6.4 Battery discharge signal
Upon detection of excessive battery discharge the Indicator delivers the following signals with
the frequency of 2 times per second:
red LED lights up and goes out;
buzzer emits short tone signals;
low battery symbol lights up and goes out on the display.
These signals are issued for 30 seconds or until the user presses any button, then the Indicator
turns off.
1.6.5 Signal of registration of alpha, beta particles and photons of ionizing radiation
Upon a photon or particle registered by the detector:
1. LEDs form a light pulse:
green, if none of the alarm thresholds is exceeded;
red, if at least one alarm threshold is exceeded or radioactive contamination was
detected in DETECTION mode;
2. The buzzer makes a click.
1.6.6 Signal of manual measurements start / ending
The buzzer emits a short single tone signal.
1.6.7 Alarm signals
Upon exceedance of any of the thresholds of the current measurement mode, or upon
detection of radioactive contamination in DETECTION mode, the buzzer emits a particular (for
each type of alarm) sequence of tone signals.
1.7 Elements of Graphical Interface
Graphical interface of the Indicator is represented by the following screens:
measurement modes screens;
menu screens;
settings screens (dialogues);
tip screens (prompts).
The screens are divided into zones. In the top part of the display there is the line of header of
the screen (hereinafter referred to as the header), at the bottom there are one or two message
bars. Between the header bar and message bar there is the screen work area where the
measurement results, menu, dialogues elements and background information are displayed.

Work area
On the left side of the screen there are two icons showing the type of displayed readings:
If icon is active, the dose rate of gamma radiation is displayed;
If icon is active, the integral dose of gamma radiation is displayed.
If "Down" button is pressed, the integral dose is displayed, otherwise the dose rate is displayed.
Large digits (see. Fig. 4, field 7) show the numerical value of the dose or dose rate. If the
statistical error is greater than ±50% (value is not valid), gray dashes are displayed instead of
the numbers. Values below the first threshold are shown in green. Values higher than the first,
but lower than the second threshold are shown in yellow, values above the second threshold
are shown in red.
Along with value (of dose or dose rate), the screen displays the corresponding statistical error
(field 5), and measurement units (field 6).
At the bottom of the screen the measured value is displayed on analog display with logarithmic
scale. One indicator scale division corresponds to tenfold change of displayed value. Green,
yellow and red areas correspond to the levels of alarm.

11
Message bar
The message bar (see. Fig. 4) shows the current alarm level. The following are the messages
displayed in descending order of priority:
"No data" –the measured value is invalid;
"Dangerous" or "Alarm level 2" –the value is greater than or equal to the second
threshold;
"Radiation" or "Alarm level 1" –value is greater than or equal to the first threshold and
less than the second threshold;
"Norm" –value is less than the first threshold.
"Radiation" and "Dangerous" messages are issued for the values of the dose rate, and "Alarm
level 1" and "Alarm level 2" messages are issued for values of the cumulative dose.

Right –"Menu" buttons.
The name of the current measurement mode is indicated as the function of "Power" button.
If by "Menu" button the measurement mode is changed, the message bar will show "Mode",
and in other cases –"Ok".
1.8 Event log
The non-volatile memory of the Indicator has an event log. Both measured values and
attributes of some important events and statuses of the Indicator are recorded in it. Each entry
contains indication of current time. It is possible to view the contents of the log only by
connecting the Indicator to the computer using support program RadiaScan.exe (included in
the supply package). The Support Program downloads, views and saves all the log entries of the
Indicator in the the database of the computer.
The following modes of the log operation are implemented:
"Normal" –in this mode the results of measurements and characteristics of the most
important events and statuses of the Indicator are logged;
"Advanced" –in this mode the results of measurements and characteristics of all
registered events and statuses of the Indicator are logged.
Memory of the log has 60 pages. After filling the current page the Indicator opens a new one
and continues recording. Erasing the memory of the log is made page-by-page and can be made
both automatically or manually. In the case of automatic erasure at a shortage of space for new
records the Indicator empties a page with the oldest records. When manually erasing the
memory the user can choose either complete erasure of the log, or specify the number of pages
(with the oldest records) to be deleted. When deleted all pages with the records are lost
forever.
