1 Welcome
Congratulations on your recent purchase of the Mini Rad-V G2 Vehicle-Mounted Radiation Detector. The
Mini Rad-V quietly scans the environment around the vehicle to find any sources of gamma radiation. If
gamma radiation is detected, the Mini Rad-V gives clear audio and visual alarms proportional to the
presence of radiological materials nearby. The Mini Rad-V features a simple layout and automatically
calibrates itself to natural background radiation.
2 G2 Updates
The G2 model includes improved ruggedization enhancements to the internal electronics and the exterior
housing. Upgrades to the surface mounting and component potting on the inside of the case and a more
robust FET to contribute to a significantly improved durability and anti-shock capabilities. An anodized
aluminum shield protects the detection unit at the cable penetration. A self-diagnostic feature based on
various light sequences displayed on the display/alarm notify the user of specifi , and the installation process
was re-evaluated and is now simpler and more straightforward.
A new shield has been included to mitigate the collection of snow, ice and moisture on the Exterior Detector
housing.
The entire installation process was re-evaluated as well and is now simpler and more straightforward. That
required a new more robust FET and subsequently more revamping of the board.
3 Installation Warning
Warning: Do NOT apply power to the In-Cab Display module before connecting it to the External
Detector module.
Please read all installation instructions in section 5 before installing the Mini Rad-V system.
Applying power to the In-cab Display module before connecting the other communication cable can
provide an electrical shock and cause an electrical failure to the In-cab Display module and void the
warranty. The In-Cab Display module should always be connected to the External Detector module
BEFORE power is applied. Failure to follow the instructions in this manual may damage the unit.
4 System Overview
4.1 Modules

4.2 External Detector Module
The External Detector module houses a 0.5” diameter x 1.5” Cesium Iodide Scintillation crystal with a
high-sensitivity photo-multiplier tube. It detects gamma radiation within the energy range of 30 keV to 3
MeV. It takes readings in less than one second.
4.3 Protective Shield
Included with the G2 model, the protective shield adds an increased level of environmental protection by
prohibiting the buildup of snow and ice on the cable and connector on the External Detector module. The
protective shield comes attached to the External Detector module.
4.4 Cables
There are 2 cables included with the Mini Rad-V –the Power cable and the Communication cable. The
Power cable connect the In-cab Display module to the vehicle power. The Communication cable connects
the In-Cab Display module to the External Detector module.
The standard cable lengths for both cables are 20 feet long. Longer cables lengths of 35’ and 50’ are offered
as options.
4.5 Maintenance
The External Detector module is designed to MIL-STD-810 environmental standards for rain, shock, and
vibration. The unit is sealed to reduce intrusion from dust, humidity, and salt fog. It may be cleaned safely
with mild soap and water using a warm, wet cloth.
5 Installation Instructions
Please refer to your vehicle manufacturer’s manual for specific installation guidance for your vehicle,
particularly for mechanical mounting of the Mini Rad-V modules, routing of the power and communication
cables, and connecting the Mini Rad-V to vehicle power. D-tect Systems assumes no responsibility for
damages to any vehicle, other electronic devices, or this product incurred during installation.
5.1 Installation Steps
Warning: Do not apply power to the In-Cab Display module until the External Detector module is
connected to the In-Cab Display module with communication cable.
The In-Cab Display module must be connected to the External Detector module BEFORE power is applied,

8. Connect the power cable to the power source.
9. Test to make sure the Mini Rad-V powers up and responds to a radiation source.
5.2 External Detector Module Installation
The External Detector module houses the radiation detection components and is designed to be placed on
the exterior of the vehicle. It is attached to the vehicle with four ⅛” screws (spaced 2” apart on both ends
of the module). The sensitivity of the device decreases with the amount of material between the detector
and any potential radiation sources, so it is best to mount the device in a secure location with good exposure,
such as behind the front grill or on the front bumper.
Make sure that neither the mounting equipment nor the position of the module affects the operation of the
vehicle in any way. Take special care if mounting the External Detector module under the hood to avoid
placement near the engine block, exhaust lines, compressor, or other hot/cold areas, as exposure to extreme
temperatures may damage the device. Also, make sure to avoid engine belts and electrical wires, and
confirm that the power and/or communications cables of the modules are secured and isolated from moving
parts and hot surfaces.
Figure 5: External Detector Module
•Place on the exterior of the vehicle in a
location with good exposure (i.e.
BEHIND the front grill or on the front
bumper).
•Avoid hot or cold areas of the vehicle,
such as locations near exhaust lines,
the engine block, or the radiator.
•Make sure the cable reaches from one
unit to the other before firmly securing
either unit.

5.3 In-Cab Display Module Installation
The In-Cab Display module should be placed within easy reach of the operator and should be attached
securely to a solid surface. The module is attached to a support that is secured by three ¼” screws spaced 1
¼” apart. Make sure that the In-Cab Display module does not block the view of the driver or interfere with
vehicle controls and/or other equipment.
Contact your local Department of Transportation for information regarding regulations for dashboard-
mounted displays, as these may vary from state to state. The In-Cab Display module must be connected to
the External Detector module via the communication cable. Depending on the vehicle model and
configuration, this cable can usually be run under the dashboard and through the engine compartment.

6 System Operation
6.1 Start up
To operate the Mini Rad-V, you first need to connect the cables. Both the communication and power cables
connect to the back of the In-Cab Display module. To connect the cables, adjust the cable until it fits onto
the post, then turn the cable connector to the right until it locks firmly onto the post. To release the cable,
turn the connector in to the left until it stops. From there, the cable should pull away from the post.
When power is applied to the In-Cab Display module, the blue LED labeled ‘Power’ will light up and the
unit will begin a power-up and calibration sequence, indicated by a beep and a flashing blue LED. During
the 30 second calibration interval, the unit will measure naturally occurring background radiation and
calculate a threshold. (This threshold will be the baseline from which a radiological alert will be indicated
to the operator.) The blue LEDwill blink once more to indicate that the backgroundcalibration has finished.
If the Mini Rad-V stops detecting normal background radiation levels for a period of time (such as if it is
taken into a parking garage), the Mini Rad-V will recalibrate itself. The device will beep and the blue LED
will flash to indicate the 30 second calibration phase. When calibration is complete, the Mini Rad-V will
beep once more and go into detection mode. This keeps the Mini Rad-V at maximum sensitivity levels in
all environments.
6.2 Power
The unit can be powered by any of the following sources: a car adapter plugged into a cigarette lighter or
auxiliary power source, two lead lines attached to the fuse box, or an AC power converter for standard
outlets. After plugging in the unit, check to make sure that the blue LED on the front face of the In-Cab
Display module is on.
6.3 Alarm
The In-Cab Display module will alarm (audibly and with a blinking red LED on the front face of the In-
Cab Display module) when the presence of gamma radiation exceeds threshold background levels. The
frequency of the audio and visual alarms will increase proportionately to increasing levels of gamma
radiation. The audio alarm can be silenced by pressing the ‘mute’ button on the front face of the In-Cab
Display module. To reactivate the audio alarm, press the mute button again. The red LED will continue to
flash until the External Detector module no longer detects radiation above background levels.
6.4 Periodic Testing
A periodic test is recommended to ensure the Mini Rad-V is working properly. This test can be performed
with the use of a small radiation source such as a 1.0 µCi Cs-137 check source. Hold the small radiation
check source near the External Detector module. The In-Cab Display module will emit an audible alarm
and the small red LED light will flash.

8 Trouble Shooting Guide
The Mini Rad-V In-Cab Display module emits various signals under certain conditions during bootup and
calibration, during radiation alarms, and when the system is experiencing a type of failure. The trouble
shooting table below describes various sequence, conditions and suggestions for each situation.
Table 1: Trouble Shooting Table
Sequence
Condition
Suggestion
At power on, the blue light
flashes for 30 seconds,
followed by an audible beep
and simultaneous flash of the
red light.
This is the expected sequence
at initial boot up and
calibration.
N/A
While on, the blue light starts
flashing for 30 seconds,
followed by an audible peep
and simultaneous flash of the
red light.
This is a normal sequence.
When the device senses lower
background radiation levels, it
will recalibrate.
N/A
While the blue light is on, the
red light begins to flash, and
the audio begins to beep.
This is the expected behavior
when detecting the presence
of gamma and x-ray radiation.
Radiation is detected. Use a Mini
Rad-D to localize the source, then
use a Rad-ID to identify the type of
radiation present.
If it is confirmed a radiation source
is not near, and the device continues
to alarm, then contact customer
service.
