General Information

The NeutronRAE II an intrinsically

safe rapid detector of γ-ray (gamma)

and neutron radiation sources.
of its high sensitivity, it can alert

rst responders to the presence

of a radiation threat well before
they might be exposed to health­threatening levels.
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.

It is the only

Inserting & Replacing Batteries

NeutronRAE II uses two AA alkaline 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.

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:

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.

or

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.

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:

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
TIME Time, date, and time unit has been on
STAT Detector status (battery voltage and internal temp.)
COMM
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.

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.

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.

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.

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.

The Vibrator is tested. Press the SET button to start
the next test.

Mode. During any test, if the SET button is not
pressed within 60 seconds, the unit will automatically
move on to the next test.

Programming Mode

Programming Mode is used to change alarm settings and

detector settings (units of measure, time, etc.).

Note: Changes to some parameters cause the detector to
automatically restart or recalibrate.
