SAFETY INSTRUCTIONS
Due to the rather high detector sensitivity the dose rate measuring range of the RadEye G-10 is limited to 100 mSv/h.
A correct dose integration is performed only, if the instrument
does not display over load “OVERLOAD”
The RadEye G-10 is suited to perform highly accurate dose
measurements at low to medium dose rates. It is however not
intended for use as a legal personal dose meter.
The RadEye G-10 is not well suited for pulsed radiation.
There will be a significant under estimation at dose rates during pulse of more than 0,2 R/h.
Do not use the unit if error messages appear on the screen.
The earphone connector at the bottom side of the instrument
must be exclusively used by equipment that is specified for
use with RadEye G-10.

1. Introduction
The pocket sized RadEye G-10 is a sensitive and rugged device to measure the ambient equivalent dose rate (Sv/h) of
gamma and X-ray radiation.
The characteristic feature of the RadEye G-10 is the use of
sophisticated low power technology components and microprocessor based, fully automatic self checks. No maintenance
is required.
The RadEye G-10 incorporates a sensitive GM tube detector
allowing the detection of low to medium radiation levels.
The last 1600 mean and maximum values of the dose rate and
count rate are recorded internally and can be read out via serial
interface.
Additionally the RadEye G-10 logs the last 250 alarms, errors
and changes of the configuration. All events can be read out
via serial interface.
A real time clock is provided to add a time stamp to all buffer
data.

Iw/Tr/Ff 22.01.2010
The measured values in the history memory remain stored.
The real time clock for time stamp of history values and logbook continue operation, if batteries are exchanged without
delays. If Real Time Clock is set, actual time and date is displayed for 3 s.
To keep RTC running during battery exchange, batteries must
be exchanged without delays.
RTC will always be reset, if instrument is stored without batteries for more than 10 seconds.
History data and measurement parameters are stored permanently, even if batteries are removed.
RTC information is only required, if the instrument is
switched off and on during operation and if correct timing
information for history and logbook entries is needed.
For the last power on interval, the relative time information of
logbook and history is corrected to actual PC clock time during read out. In these cases the setting of the clock is not required.

The first alarm thresholds for dose rate is around 200 - 500 %
above the typical normal background and allow sensitive, but
false alarm free dose rate monitoring with a reasonable fast
response time. The alarm thresholds for the dose are set to the
maximum possible values, thus being deactivated. With the
setting of the history recording interval of 120 s , the last 52
hours of operation will be stored in the history memory.
These default values are reasonable for the majority of applications. For special applications the parameters (except calibration parameters) can be changed with the help of the optional PC-program „RadEye.EXE“ and the cable 42540/29.
Furthermore, additional monitoring modes can be activated.
The calibration parameters can only be changed in the factory
using special software tools.

4.5 Process description for detection of radiation
sources.
Direction of maximum response
To detect hidden radiation sources, the dose rate alarm threshold must be set to the lowest value, that does not produce fail
alarms. This is typical a value of 0,3 µSv/h to 0,5 µSv/h.
Due to it’s almost 100 times higher efficiency, the RadEye
PRD is more suited for this task, than the RadEye G-10.
Subsequently, the operator passes the object while keeping
thereby the distance between the monitor and the object to be
checked as small as possible.
With an alarm occurring, the operator should move the instrument while observing the display in order to localize the
position of the source. Please note, that the alarm can occur up
to a few seconds after passing the nearest distance to the
source.
If the alarm disappears after a few seconds, this alarm is to be
considered as a statistically released false alarm.
In case a radiation source has been detected, the radiation intensity is indicated. (see chapter 3.2).

key. After 8h this warning comes up again. The battery needs
to be changed. However, the RadEye can still be operated for
several hours.
If the battery voltage falls below 2V, the battery symbol starts
flashing. An acoustic warning is generated every 8s and can’t
be acknowledged. The battery needs to be changed as soon as
possible.

6.1.3 Creating a Measurement File
The actual measured values Count rate and Dose rate that are
shown in the "Measurement" display field can be stored in a
measurement file.
To do this, open the File menu, click on Open Logfile..., and
enter path and name. The file is stored with the file name extension ".log".
If another file of the same name exists, the system asks
whether that file shall be overwritten or the new measured data
shall be appended to the existing data.
Once you have pressed OK to confirm the entries, the measurement logfile is created and the polling measured data is
stored in the scan interval you have defined. An open measurement file is indicated by the name and the path of the
measurement logfile that appears in the top right-hand corner
of the window.
To terminate data storage, open the File menu and select the
Close Logfile menu item. No further data is recorded.
Open the File / View Logfile... menu to view the measurement
logfile.
For training and demonstration a prior recorded logfile can be
replayed by opening Replay logfile.

With the buttons Start and Stop together with the polling in-
terval the replay can be controlled.
Close Replay switches back to accessing measurement values
via infrared interface.
The measurement logfile is an ANSI text file with columns
that are separated by <TAB>. This enables this file to be read
easily into other programs (such as Excel) where the data can
be processed.
The first line of the measurement logfile contains the unit
name, the file name, and the path. Serial number and Device
identification are specified on the second line.
Date and time of the measurement are specified in the columns
under the field names "mm.dd.yy" and "hh:mm:ss". The time
setting corresponds to the PC system time.
The "Counter" column contains the numerical value of the
counter measurement. The "Unit" column informs about the
unit. The "Dose Rate" column contains the numerical value of
the dose rate measurement. The "Unit" column informs about
the unit (Sv/h or R/h).
