RADEX RD1212 - Radiation Detector is designed to
evaluate background radioactivity levels of the environment
around you as well as check radioactivity of materials and
products.
The device has the following capabilities:
• measures radioactivity
• stores measurement results in memory
• data transfer to PC
• self-testing
• Time and Date functions
• audible alarm
• vibration alarm
• integratedashlight
• multilingual (Eng, De, Fr, Rus, Jp)
Please note that this device uses statistical
probability function to calculate radiation values.
Even in identical circumstances, two identical
devices may show varying results.
The results obtained with the help of this device
should not be used as ofcial and conclusive. This
device has not been evaluated by any governmental body.

To enhance reliability of the measured result, it is
advisable to wait until the device completes not less
than 10 measurement cycles.
Measurements with Background Function
While taking measurements with Background Function,
two radiation values are displayed simultanesously:
a
b
а - excess over (b).
b - value of background radiation.
To take measurements with Background Function it is
necessarytorstmeasuretheBackgroundRadiation.
1. Select menu background background.
2. A list of 5 measurement points will be displayed.
3. Select measurement point in open site (refer to page 10).
4. Press , a measurement cycle will be initiated. At the
end of the cycle a list of points/locations with the results of
measurement will appear of the display screen.
5. Repeat items 3 and 4 above for the remaining points.
6. Press , a menu will be displayed on the screen, a tick
symbol will appear next to item on.
Number of measurement points can be reduced
down to one point, to do so press key after any
measurement cycle. Please note this reduces the
reliability of measurements.
If Background radiation was measured earlier, you may
proceed with measuring current radiation (in excess of
background).
1. Enter menu background.
2. Move to on position and press .

OPERATIONAL RESTRICTIONS
OBJECTS
Search of radioactivity source location
1. Disable the threshold function.
2. Switch ON the audible alarm and/or Vibration signal
functions
3. Move the device over probable location of the
radioactivity source. When doing so pay attention not
only to measurement indications but also to frequency
of signals. The signals’ frequency will increase as the
source is approached and respectively decrease as the
source is moved away from.
Performing radioactivity survey of living and public buildings
1. Perform radiation background measurements on the
open site near the surveyed building in 5 locations.
2. Perform measurements inside the building.
3. If the registered radiation inside a building exceeds
radiation at the open site by more than 0.2 mSv/h,
this may indicate presence of unfavourable radiation
environment.
• Do not subject the device to high temperatures
• Avoid prolonged exposure to direct sunlight
• Do not attempt to disassemble and repair the device
• Avoid impacts to the device
• Protect the device from liquids
• Do not place the device into microwave oven
• Do not carry on examination/survey in the presence of
operating air ionizers/ozonizers
• If you do not plan to use the device for more than a
month, remove batteries
