Introduction
The D3S ID is a unique radiation detection solution which incorporates the
Kromek D3S detector with an Android smartphone. The D3S integrated
technology combines a CsI(TI) gamma ray spectrometer and a non-He3 compact
thermal neutron scintillator detector.
The D3S hybrid gamma/neutron platform neatly combines high sensitivity, small
form factor and a long battery life to produce an ideal portable instrument, that
seamlessly connects via Bluetooth with the D3S ID smartphone application.
1 Power On / Off
The D3S is powered on by holding the power button for 1 second and the
indicator light will start to flash.
The D3S is powered off by holding the button for 5 seconds and the indicator
light will go out or turn white if it is still connected to a power source.

1.1 Warm-up Time
Warm-up time is the time required for the D3S
ID to become fully functional from a dead start
(off state).
This involves switching the already
paired D3S detector and smartphone on,
opening the D3S ID application and for
the status to be connected and ready. This is
indicated by the tick mark at the bottom right
hand side and that gamma and neutron dose
rate are displayed.
The warm-up time is ~40 seconds.
2 Charging the D3S
The D3S detector can be charged by connecting power via the USB cable or by
placing the D3S into the Kromek induction charging station.
2.1 USB Charging
When power is connected via the USB cable, the D3S will start charging and the
indicator light will pulse until it is fully charged then it will solidly illuminate.
If the D3S is powered off while charging, the indicator light will be white.

the D3S
▪ Connection shows the type of
connection between the D3S and
smartphone (Bluetooth or USB)
▪ Calibration shows the K-40 tracking
status; “Acquiring” shows when counts
of natural K-40 are being acquired.
When enough counts have been
acquired to feed into the algorithm,
“Tracking” status is shown
▪ Battery shows the battery level of the
D3S. At 15% it will turn yellow, and at
5% it will turn red.

5.1 Search Mode
Search Mode is designed to be used to
continuously scan and search for radiation
whilst the user is going about their normal
duties.
The scan is initiated automatically once a D3S
is connected. It will continue to scan until the
D3S is manually disconnected or the phone is
turned off.
The scan will also pause when the user
navigates to the Confirmation Mode (Section
5.2) and will resume once user navigates back
to the Search Mode.
The time graph showing background reading
in counts per second (CPS) in 10 minutes
period can be displayed by dragging the slide
card up.
The device uses a three second rolling
average to detect and identify radioisotopes
and the screen is updated every second.
When radiation is detected the smartphone will
vibrate and an audible alarm will sound ‘Alert’
and name the detected isotope e.g. ‘Alert
Americium-241 detected’ or ‘Alert high neutron
count’.
A pop-up window will be displayed, which
contains information on the detected isotope
and isotope classification (NORM, Medical,
Industrial or Special Nuclear Material).
Click “SNOOZE” to acknowledge the alarm.

MAL-OPS-0927 Revision 4.0 Page 14 of 52
If more than one isotope is detected, an
indication “Alert 1 (of 2)” will be displayed on
the pop-up window. Swipe to the left to display
the next alert.
Click “SNOOZE ALL” to acknowledge the
alarm.
Visual notification panel of the alert will be
displayed until the radioactive source is
removed.
The icon on the time graph can be clicked to
display the alarm information.
Below is the list of icons for each isotope
classification.

Click the “Start Scan” button to initiate the
Confirmation Mode scan and confirm the
isotope identification.
Note: The Search Mode scan will stop once
switched to Confirmation Mode

MAL-OPS-0927 Revision 4.0 Page 16 of 52
The confirmation scan can be conducted from
30 seconds up to 5 minutes. During the scan
gamma dose rate and neutron count rate are
updated every second. Isotope identification is
updated and displayed every 30 seconds.
The grey triangle moves depending on the
number of gamma counts the device is
detecting. The grey triangle should be kept
within the yellow bar for optimum identification.
After 30 seconds, if a radioisotope is identified,
the smartphone will vibrate, and an audible
alarm will sound ‘Alert’ and name the detected
isotope e.g. ‘Alert Americium-241 detected’ or
‘Alert high neutron count’.
A pop-up window will be displayed, which
contains information on the detected isotope
and isotope classification (NORM, Medical,
Industrial or Special Nuclear Material).
Similar to the Search Mode, if more than one
isotope is detected, an indication “Alert 1 (of 2)”
will be displayed on the pop-up window. Swipe
to the left to display the next alert.
Click “Continue” to continue the scan for up to
5 minutes or “Stop ID” to stop.

MAL-OPS-0927 Revision 4.0 Page 17 of 52
Visual notification panel of the alert will remain
displayed. If more than one isotope is detected,
an indication “Alert 1 (of 2)” will be displayed on
the pop-up window. Swipe to the left to display
the next alert.
“File with Reachback Report” displayed on the
notification panel is a clickable link which opens
the Reachback Report panel.
The acquired data is saved onto the phone.
