SAFETY INSTRUCTIONS

The RadEye G20 is suited to perform highly accurate dose
measurements. It is however not intended for use as a legal
personal dose meter.
The RadEye B20 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.
In case the dose rate measuring range is exceeded, the value of
the upper end of the dose rate measuring range is used for the
dose integration.
The instrument must not be used in explosive atmosphere.
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 G20.

The RadEye G20 is not suited for pulsed photon radiation.

Iw/Tr/Ff 26.11.2012

1. Introduction

The instruments of the RadEye G20 series are modern com­pact survey meters for sensitive gamma and x-ray dose rate
measurements. The instrument incorporates a sensitive GM
pancake tube detector allowing the dose rate measurement
from background levels. ER-versions extend the measuring
range up to 100 mSv/h (10 rem/h respectively 10 R/h).

RadEye G20-10 and RadEye G20-ER10 are energy compen­sated according to the SI-standard units of ambient dose
equivalent H*(10) (= “deep dose”) and show a flat response
from 17 keV to 1.3 MeV. RadEye G20 and RadEye G20-ER
are energy compensated according to roentgen units (40 keV
to 1.3 MeV). In this context it is important to note, that users
may select “R/h, Sv/h or rem/h” as a display unit, with the
understanding that the energy response characteristic is not
altered by this selection. Within the RadEye G20 family the
relation 1 R = 1 rem =10 mSv is used.

The last 1600 mean and maximum values of the count rate or
dose rate are recorded internally and can be read out via serial
interface. Additionally the RadEye G20 logs the last 250
alarms, errors and changes of the configuration. All events can
be read out via serial interface.

RadEye G20 DB-067 E 1-1
Iw/Tr/Ff 26.11.2012

A real time clock is provided to add a time stamp to all buffer
data. The characteristic feature of the RadEye G20 is the use
of sophisticated low power technology components and mi­croprocessor based fully automatic self checks. No mainte­nance is required.

All or selected menu functions described in 3.1 can be con-

figured to be invisible and inaccessible by the user.

Thus the instrument can be configured to both, an ex-

tremely simple mode allowing just LCD-illumination and

alarm acknowledgment to a very versatile mode for the

more experienced user.

2. Installation and start-up

2.1 Scope of delivery

The RadEye G20 instruments are delivered in a box together
with two AAA cells and an operating manual.

Ample space is provided for a data cable or a test adapter.

.
Ordering information for accessories see chapter 11

RadEye G20 DB-067 E 2-1
Iw/Tr/Ff 26.11.2012

2.2 Inserting the batteries

The two AAA-Alkaline cells as delivered with the instrument
allow about to 900 h with RadEye G20/G20-10 respectively
700h with RadEye G20-ER/G20-ER10 of normal operation.
AAA size rechargeable batteries can be used as well.

• Switch off the measuring instrument.

• Remove rubber sleeve.

• Open the cover of the battery compartment.

Use of a coin is recommended.

• Exchange the batteries according to the shown polarity.

• Close the compartment cover hooks first, care for the rubber

seal being in its groove.

• Switch on the unit again. (see chapter 2.4)

The instrument continues working in the operating mode set last
(see chapter 3.2).

2-2 DB-067 E RadEye G20
Iw/Tr/Ff 26.11.2012

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 (see chapter 2.4).
After power on the RadEye first display zero dose rate. After
the first detector pulse the measurement will be started.

If correct timing information of logbook and history is required,
the Real Time Clock should be set by means of the PC-program
or via menu function “Set Time/Date”.

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.

Even without RTC information the relative time information of
logbook and history is corrected to the actual PC clock time
during read out unless the batteries had not been removed be­tween the event and the data read out.

5. Measurement units

Direction of maximum response

To detect hidden radiation sources, the alarm threshold must be
set to the lowest value that does not produce fail alarms. This is
typical a value of 0.2 to 0.3 µSv/h (20 – 30 µrem/h, µR/h).

Due to it’s almost 100 times higher efficiency for gamma emit­ters, the RadEye PRD is more suited for this task, than the
RadEye G20.

For measurements at spots with high local contamination respec­tively dose rate, the extension adapters 42506/7075, /7076 and
/7077 in conjunction with the adapter 42506/7078 can be used.

RadEye G20 DB-067 E 5-1
Iw/Tr/Ff 26.11.2012

The user may as well select R/h as a displayed measuring unit
with the understanding that 1 R/h is simply set equal to 1 Rem/h
and that consequently energy dependant deviations to the expo­sure rate (and air kerma rate) will occur.

The RadEye G20-10 and G20-ER10 is factory calibrated to the
ambient dose equivalent rate H*(10) in a depth 10 mm for Cs-137
gamma radiation (662 keV).

For details of the response curves see technical data section.

5-2 DB-067 E RadEye G20
Iw/Tr/Ff 26.11.2012

6. Functional test

When the instrument is switched on, it will show zero dose rate
until the first detector pulse occurs.
The radiation meter performs continuous self-check routines. A
complete failure of the detector during operation will be indicated
after 1 minute on the LCD and be announced by the beeper. The
same applies to the battery voltage.

6.1 Functional test

To carry out a simple test, shortly press any key. A short audible
pulse has to be released and the LC display is illuminated for
some seconds.

The heart symbol next to the battery indicator must be “beating”.
This indicates that the cyclic tasks as calculating measurement
values and checking for alarm thresholds are active.

RadEye G20 DB-067 E 6-1
Iw/Tr/Ff 26.11.2012

6.2 Failure indication

In case of a failure the beeper generates a sharp single pulse every
32 s.
The corresponding failure message is displayed in the LCD:

6.4 Response test with test adapter

The test-adapter 42549/48 offers a convenient way to verify the
radiation response performance of the RadEye G20. This “check
source” contains 50 g of natural Lu2O3 (which corresponds to
approximately 2400 Bq Lu-176). Due to the low resulting gamma
dose rate this yields a net dose rate of the RadEye G20-10 of ap­proximately 0.25 µSv/h. The operational advantage of the test­adapter is given by the fact that each and every individual adapter
has the same emission rate, and that due to the long life time
(3.6E10 years), which exceeds the age of the universe signifi­cantly, neither source specimen, nor half life corrections need to
be performed. Furthermore the specific radioactivity (approxi­mately 48 Bq/g) of natural Lu2O3 is well below the threshold
values according to IATA, respectively NRC (USA) or
StrSchV(Germany) in respect to the scope of dangerous goods
definition and transport regulations of radioactive material.
At a typical background count rate < 0.1 µSv/h, it is sufficient to
verify the response within 300 seconds for a 10 % statistical un­certainty.
For a faster response verification Ba-133 check sources (or other
gamma sources) in the range of 100 – 400 kBq are suggested.

6.5 Low Battery warning

If the battery voltage is below the configured threshold (see chap­ter 4.11) the following warning appears:

The beeper generates a single pulse every 32s. This acoustic
warning can be suppressed by pressing the alarm acknowledge
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.

RadEye G20 DB-067 E 8-3
Iw/Tr/Ff 26.11.2012

The RadEye.EXE software offers to search for a connection to
the RadEye unit on other available serial ports.

If there is a faulty connection between the unit and the com­puter, the program shows the error message “Data transfer to
instrument fails”

In this case, you must check whether:

• The RadEye has been positioned correctly in the desktop

holder (with rubber boot) and the RadEye is turned on.

• The infrared transmission windows are clean

• The correct serial interface has been selected.

Open next the serial interface step window in the RadEye.EXE
software: Configuration / Com settings... menu. The used
serial port has to be selected next.

8.6 RadEye lost date and time settings

The date and time information is lost, each time the batteries
are removed or below the required voltage for operation. The
simplest way to program the date and time is to use the “syn­chronize” function of the optional RadEye.EXE software.
Please refer to chapter 7.5.1. Else the current date and time can
be set also through the RadEye’s menu “Settings” / “Set Date /
Time”

8.7 RadEye’s battery status is lower than expected

Please check if the correct battery type is selected under “set­tings” / “Batt. type” and change the type in case. Rechargeable
batteries supply a voltage of 1.2V each, while Alkaline batter­ies provide 1.5V.

Rechargeable batteries offer also a more steep drop from ac­ceptable battery voltage to “battery low” than Alkaline types.
