Warnings
For safety reasons, this equipment must be operated
and serviced by qualified personnel only. Read
and understand the user manual completely before
operating or servicing.
Computer Interface
Do not transfer data by means of the Bluetooth®interface in
hazardous atmospheres.
Static Hazard
Clean only with a damp cloth.
Long-Term Storage
Reliable performance of this radiation detector is based upon
regular usage. For long-term storage, the battery should be
disconnected. Preparation for use after long storage requires
installation of the batteries and a warm-up period of at least
10 minutes for the sensors to equilibrate. The user should
recognize that sensor life is based upon the purchase date.

personnel qualifié. Étudier le manuel d’instructions
en entier avant d’utiliser, d’entretenir ou de réparer
l’équipement.
Câble de Computer
Ne transférez pas les données au moyen de l’interface de
bluetooth en atmosphères dangereuses.
Danger Risque D’origine Electrostatique
Nettoyer uniquement avec un chiffon humide.
Stockage à Long Term
Le fonctionnement durable de ce détecteur de rayonnement
est conditionné par une utilisation régulière de celui ci. Lors
d’un stockage à long terme, la batterie doit être déconnectée.

General Information
The NeutronRAE II an intrinsically
safe rapid detector of γ-ray (gamma)
and neutron radiation sources. Because
of its high sensitivity, it can alert
rst responders to the presence
of a radiation threat well before
they might be exposed to health-
threatening levels. It is the only
personal radiation detector with a loud
audible alarm, big, bright ashing
LEDs, and a vibration alarm. For stealth operations, law
enforcement personnel can disable each alarm separately.
NeutronRAE II’s water-resistant design makes for reliable
operation in wet environments. Its sensitive Cesium Iodide
(CsI) and Lithium Iodide (LiI) scintillators provide fast (less
than 2 seconds for gamma/5 seconds for neutron) response to
radiological threats.
The NeutronRAE II accumulates approximate dosage. Stored
dosage data can be cumulative or cleared and reset for each
use period.

6NeutronRAE II
Inserting & Replacing Batteries
NeutronRAE II uses twoAAalkaline batteries as its power
source (use only Duracell MN1500 or Energizer
E91). To change the batteries:
1. Use a coin or screwdriver to open the
cover on the side of the unit. Turn the
screw counterclockwise to loosen the
screw, and then tilt
the cover off.
2. Insert batteries into
the compartment
according to the
legend on the rear of the NeutronRAE II, making
sure the batteries’polarity is correct.
3. Replace the cover and turn the screw
clockwise to secure the cover.
Note: When you touch the cover’s internal
contacts to the batteries, NeutronRAE II’s alarm
sounds briey, indicating that the batteries are
not dead. If the sound is distorted or irregular, the batteries
should be replaced.

User Interface
NeutronRAE II’s user interface consists of the display, LEDs,
alarm transducer and two buttons, labeled MODE and SET.
The LCD display provides visual feedback that includes
time, functional mode, battery condition, and gamma
radiation measurement.

Turning NeutronRAE II On and Off
Turning NeutronRAE II On
Press and hold the MODE button for 3 seconds.As
NeutronRAE II starts up, the following occur:
1. A long beep sounds (if the buzzer is set to On), and
unit information and the current rmware version are
displayed. The LEDs and vibrator undergo a self-test.
Important! If your NeutronRAE II displays
“Gamma sensor failed,” “Neutron sensor failed,” or
“All sensors failed!” contact your distributor or RAE
Systems service at 408-952-8200. Do not attempt to
use or repair the unit. There are no user-serviceable
parts in the NeutronRAE II.
2. Unit self-check. The time and battery status are
displayed:

10 NeutronRAE II
During the 20-second self-check, the detector checks
that the gamma and neutron sensors are functioning
properly. If so, the messages “Gamma sensor OK!” and
“Neutron sensor OK!” are displayed.
If the sensor is damaged or not functioning properly,
the message “Gamma sensor failed” or “All sensors
failed” is displayed, turn the unit off and contact your
distributor or the RAE Systems service department.
3. The datalog type is displayed, followed by the gamma
alarm mode.These parameters can be changed in
or
or
or

11
www.raesystems.com
Programming Mode, described later in this guide.
4. Gamma background calibration reading (only if the
NeutronRAE II is in Search Mode). The NeutronRAE
II performs a 36-second background reading
countdown.
When background calibration reading is complete, datalogging
starts (if Continuous Datalogging is enabled) and the unit is in
Normal Operating Mode. The display looks like this:

or

12 NeutronRAE II
Turning NeutronRAE II Off
Press the MODE button and hold for 5 seconds. The detector
counts down 5 seconds and then turns itself off. Do not
release the MODE button until the unit counts down to zero
and the display reads “Save cong...” and “Stop unit...”
Flipping the Screen
The NeutronRAE II is easy to read, whether held in the hand
or clipped to a belt. To ip the screen, press the SET button
and hold it down for 3 seconds. When the image inverts,
release the button.
To ip the display again, press and hold SET for 3 seconds.

Operation
The NeutronRAE II has two modes: Normal Operating Mode
and Programming Mode. Normal Operating Mode is the
default; see Programming Mode, on page 20, for details on
entering and using Programming Mode.
Normal Operating Mode
In Normal Operating Mode, the NeutronRAE II detects gamma
and neutron radiation and accumulates gamma radiation dosage
data. In Normal Operating Mode, pressing the MODE button
sequentially steps the unit through the following functions:
NORM Normal Operating Mode
CAL Background calibration (only in Search Mode)
PEAK Maximum radiation levels detected since last cleared
MIN Minimum radiation levels detected since last cleared
DOSE Accumulated gamma radiation dosage since last cleared
TIME Time, date, and time unit has been on
STAT Detector status (battery voltage and internal temp.)
COMM Open BlueTooth communication with computer
TEST Self test (if Diagnostic Flag is set during start-up)
Each function remains active for 60 seconds before
automatically returning to the Normal Operating Mode.
Pressing the MODE button changes the selection from one
function to the next one in the sequence.

14 NeutronRAE II
NORMNormal Operating Mode of the NeutronRAE II.
Displays a measurement of the ambient gamma and
neutron radiation. It can display gamma in counts per
second (cps) or µR/h or µSv/h, depending on how
the detector is set up (see Programming Mode) and
neutron in counts per second. Switch back and forth
between gamma units by pressing the SET button.
Press the MODE button to step to the next function.
CAL Background calibration. This option is only active if
the NeutronRAE II in Search Mode. This option is
skipped if the detector is in Safety Mode.
Press the SET button to have the detector update the
background radiation reading.
Press the MODE button to step to the next function.

PEAK Themaximumradiationlevelsdetectedsince lastcleared.
Press the SET button twice to clear the PEAK values.
If you press SET once but do not want to clear
the readings, press MODE to return to the PEAK
readings. The PEAK values are also cleared when the
detector is turned off.
Press the MODE button to step to the next function.
MIN
The minimum radiation levels detected since last cleared.
Press the SET button twice to clear the MIN values.
If you press SET once but do not want to clear the
readings, press MODE to return to the MIN readings.
The MIN values are also cleared when the detector is
turned off.

16 NeutronRAE II
Press the MODE button to step to the next function.
DOSE The accumulated gamma radiation dosage since last
cleared.
Press the SET button twice to clear the DOSE value.
If you press SET once but do not want to clear the
DOSE reading, press MODE to return to the DOSE
reading.
Press the MODE button to step to the next function.
TIME Time, date, and run time. Date is displayed in
YYYY-MM-DD format (can be set in Programming
Mode). Time is displayed in HH:MM:SS format (can
be set in Programming Mode).

COMMCommunicate with a computer using Bluetooth®radio.
Press SETto open the connection on the NeutronRAE II
unit end. Use the ProRAE Studio Radiation Software on
your computer to download datalogs.
TEST Self test. This consists of tests to make sure all alert
functions are working properly. This function is only
enabled if the Diagnostic Flag was set at start-up.
To set the Diagnostic Flag, press and hold SET and
MODE simultaneously when turning the unit on,
instead of pressing MODE only.
Press the SET button to accept and to initiate testing.
The Buzzer is tested. Press the SET button to start the
next test.
