How does RD01 work?
The RD01 unit utilizes the Geiger-Mueller (GM) tube to detect radiation (Beta, Gamma and X-Ray a.k.a. Roentgen
rays). Radiation passes through the GM-tube and causes gas ionization to occur with inside the tube. When ionization
has achieved a certain level, an electrical discharge takes place. Each of the discharges is detected electronically and
registered within the RD01’s microprocessor. Depending on the frequency of discharges, the level of radiation is
calculated by the IC chip via a count during a certain period of time.

Units
Radiation levels are shown in micro-Roentgens/hour (μR/h) or milli-Roentgens/hour (mR/hr) where 1000 μR/h = 1 mR/h
and 1000 mR/h = 1 R/h. The abbreviation mRtg is equivalent to mR.
There are many different units to measure radiating doses.
Roentgen - in use since 1928 to measure generated radiation or exposure dose.
Sievert - in use since 1979, where 100 Roentgen = 1 Sievert, provided that only the biological effect of radiation is
considered.
If you want to convert the units to Sieverts (SI derived unit), use this conversion chart:

How to use RD01?
Beginning to use the device
1. Install the power source, for more information how to install power source, please consult the paragraph Power;
2. Turn the device on by pressing and holding the button ON down for one full second;
3. The mode radiation power is on, whenever the RD01 unit is turned on, it performs calculations non-stop;
4. Press and hold the OFF button down for 1 second to turn off the unit.
There are two measuring modes available:
1. Radiation power mode, which shows current radiation level;
2. Radiation dose mode, which shows total or accumulated radiation level since the unit has been turned on.
To switch between the measuring modes, press MENU (ON) button for less than 1 second. When radiation dose mode is
on, a yellow light will turn on.
Each of the electrical discharges gives the user a ‘clicking’ sound. If the radiation gets higher than around 2.56 mR/h, a
red light will flash rapidly and an alarm will sound with a continuous ‘beeping’ sound.
Note: The clicks and alarm beeps can be turned on/off by changing into one of four different the sound modes (see
Button instructions section for full description).
Reading current radiation in Power mode: (yellow light is off)
If the decimal point is not shown the unit is reading low radiation levels and shows it in μR/h (e.g. ‘09’ – 9 μR/h);
If the decimal point is shown the unit shows radiation levels in mR/h (e.g. ‘.15’ – 0.150 mR/h or 150 μR/h);
If the decimal point is not shown but the red light is flashing radiation levels are shown in mR/h (e.g. ‘12’ – 12 mR/h).
Reading total radiation in Dose mode: (yellow light is on)
The radiation dose is shown in mR.
Button description
There are two buttons to operate the DX-3, which allows for simple operation.
MENU (ON) button
oTo turn the unit ON, press and hold the MENU (ON) button down for one full second.

oIf the MENU button is pushed for less than one second (when the unit is on), the unit will change
modes from power mode that shows current radiation to dose mode (yellow light will come on) that
shows the total radiation detected since the unit was turned on.
oIf the MENU button is pushed again, it will switch the unit back to power mode and the yellow light
will go off.
SOUND (OFF)
oTo turn the unit OFF, press and hold the SOUND (OFF) button down for one full second.
oIf the SOUND button is pushed for less than one second (when the unit is on), the sound modes are
cycled through Modes 1-4. These Modes will not affect measurements or display readings.
oMode 1 –clicks are on; alarm is on; the green light is off
oMode 2 –clicks are off; alarm is on; the green light is flashing (once every 2 seconds)
oMode 3 –clicks are on; alarm is off; the green light is flashing (twice every 2 seconds)
oMode 4 –MUTE; the green light is flashing (twice every 2 seconds, the second light is longer)
Range
Power mode: up to 25 mR/h
Dose mode (yellow light is on): up to 100 mR
If any of the levels are exceeded the unit will show EE on the display.
Power
AAA type batteries or accumulators can be used to power the device.
To install, remove or change the battery, undo the screw on the back of the unit, open the case and unplug the battery.
Strictly observe polarity when you install power elements, otherwise the device may fail.
If the battery gets low the red light will flash once every 8 seconds –the readings are still accurate at this state. If the
battery gets too low, the unit will turn itself off.
When the device is turned off, you can leave the power elements installed - the batteries and accumulators are not spent
if the device is in standby mode. If the unit is not used for extended periods of time to save the battery power it is
recommended to remove it from the unit.
How to carry out measures correctly?
Measuring radiation background of objects:
1. Measure the level of radiation background several meters away from the target;
2. Move the device directly to the target and measure radiation background as close as possible to the target;
3. Compare the resulting data with the radiation background level measured in step 1.
The difference of readings in step 1 and step 2 will represent the radiation background of the target.
To evaluate radioactive contamination of liquids, the unit must be placed above open surface of the liquid. To protect the
unit from contact with the liquid, it is recommended that the unit should be wrapped in a polyethylene bag, but ensuring
that the wrapping is one layer of plastic only.
