4 General Information
The DoseRAE 2 personal dosimeter is a thin
electronic monitor that can directly read X-ray or
Gamma-ray dose equivalent and dose equivalent
rate. It is specially designed for use in nuclear power
plants, nuclear fuel and nuclear components
factories, and nuclear waste-processing plants, as
well as in radiation source management, nuclear
medicine, and environmental monitoring
organizations. DoseRAE 2 has dual-channel
detectors that employ a semiconductor diode and a
scintillation crystal as sensors. It can detect radiation
rapidly in a wide range, and its energy compensation
ensures accurate readings.

5 Charging The DoseRAE 2
Charge the DoseRAE 2 before its first use, and
charge it when it is not in use. The DoseRAE 2 must
be placed in its Charger/Reader for battery charging.
5.1 Charger/Reader
The DoseRAE 2 Charger/Reader can be used for
DoseRAE 2 battery charging, parameter modification
and datalog reading (when connected to a computer
running ProRAE Dosimeter software). It can provide a
DoseRAE 2 with up to 100 mA of current. The
minimum charging time is 1.5 hours.
The red LED indicates the USB power supply is on
(Power). The green LED indicates the data
transferring is on (Status).

The DoseRAE 2 Charger/Reader can be plugged
directly into a computer’s USB port, or an extension
USB cable can be employed between the Charger/
Reader and the computer if plugging directly into the
port isn’t convenient. (For information on connec-
ting the Charger/Reader to a computer, refer to page
.)62
5.2 Removing The Silicone Boot
If the boot is installed, it must be partially removed
in order to expose its electrical contacts to meet with
the corresponding contacts in the Charger/Reader.
Pull down on the bottom of the boot and stretch it,
pulling it partially off of the DoseRAE 2. Release it, and
it stays out of the way of the contacts.

Then place the DoseRAE 2 in the Charger/Reader.
After the battery is charged, reverse the process to
stretch the boot back over the DoseRAE 2.
5.3 Low Battery
When the battery voltage is low, the green LED
flashes once per minute and the LCD displays the
“battery low” icon:
After 12 hours in the “battery low” state, the instru-
ment automatically shuts off. Recharging is needed
after the instrument has automatically shut off.

5.3.1 Charging With Instrument On
During charging, the DoseRAE 2’s green LED flashes
once per second and the LCD displays the battery voltage
change:
When the battery is fully charged, the green LED
stops flashing, and the LCD displays the “battery
full” icon:
5.3.2 Charging With Instrument Off
While the battery charges, the green LED flashes
once per second and the LCD displays this:
When the battery is fully charged, the green LED
stops flashing and the LCD displays this:

6 User Interface
The DoseRAE 2’s user interface consists of an LCD
display, LED alarm, buzzer alarm, and [MODE] and
[SET] buttons. The display provides visual feedback
that includes time, functional mode, battery
condition, and radiation measurements.

7 Turning DoseRAE 2 On
Press and hold the [MODE] button for 5 seconds. As
DoseRAE 2 starts up, the LCD screen illuminates
and checks the display segments and backlight. It
then checks the display, working mode, startup, and
firmware version before performing a 30-second
countdown. After the countdown, the reading
display is shown and it begins normal detection.
The normal display shows the accumulated dose
value.

Press [SET] to see the background dose rate values:
8 Turning DoseRAE 2 Off
With the DoseRAE 2 in normal detection mode,
press and hold [MODE] for five seconds. There is a
five-second countdown, and when it reaches 0, the
word “OFF” is displayed. Release [MODE], and the
display goes blank in three seconds.
8.1 Low-Voltage Shutoff
When the battery voltage is lower than 3.3V in
normal detection mode and if there are no alarms,
the DoseRAE 2 shuts off automatically after 12
hours. It must then be recharged before it is used
again.

9 Operation
DoseRAE 2 has two operating modes:
•Normal Operating Mode
•Programming Mode
Normal Operating Mode is the default. After the unit
is turned on, it is in Normal Operating Mode.
Programming Mode is described on page 28.
9.1 Normal Operating Mode
In Normal Operating Mode, DoseRAE 2 measures
gamma radiation dose rate and accumulates readings
for dosage data. Press [MODE] and sequentially step
through all functions. Press [SET] to step through
the sub-functions.
Note: When you reach the last function or setting, it
loops back to the first item in the list (this is
indicated in the table on the next page by the thick,
dark line with an arrowhead).
