Introduction
The rad-D is a security and inspection system that detects emissions from radioactive material. The rad-D
can inspect large numbers of packages, vehicles, or personnel and can be used to guard doorways and
driveways, to scan conveyor belts of luggage or packages, or to provide radiation detection on existing X-
ray scanning machines.
The rad-D can operate completely stand-alone, providing the user with information via the rad-D Alarm
Display Panel, or it can be integrated into a computer network, allowing for real-time display and
monitoring of multiple rad-D systems, as well as integration with security command and control systems.
System Components
A rad-D system consists of one to four detectors (Figure 1), an Alarm Display Panel (Figure 2) and
optional PRM Mounting Bracket (Figure 3). There are two types of detectors, a gamma detector and a
neutron detector. The gamma detector detects gamma radiation and high-energy X-rays emitted from
radioactive materials. Gamma detectors come in two varieties, a narrow-field of view detector and an
omni-directional detector. The neutron detector detects neutrons emitted from a small number of very
important radioactive materials. Any combination of one to four gamma and/or neutron detectors can be
installed and monitored by a single Alarm Display Panel.

17.5” in length and 5” in diameter.

System Installation
General Installation:
Physically mount the detectors in accordance with the guidelines discussed below for each type of
detector. A detector can be up to 50 feet away from the Alarm Display Panel. Connect the cable from
each detector into any one of four detector ports on the Alarm Display Panel. The rad-D will automatically
know which type of detector has been connected to the Alarm Display Panel. Connect the power cable to
the Alarm Display Panel. When all cables are connected, plug the power cable into a wall plug.
When power is applied, the rad-D begins a 90 second warm-up sequence. During this time the rad-D is
performing self-tests and calibrating to the natural radiation background environment. At the end of this
phase, the Alarm Display Panel will begin showing radiation counts from the gamma and/or neutron
detectors.
60 Hz and 50 Hz power
The rad-D can operate on both 60 Hz/110 VAC (United States) and 50 Hz/208 VAC power. The rad-D
comes with a plug configured for U.S. power sockets. To use in a 50 Hz environment, attach a wall plug
converter to convert the rad-D U.S. wall plug to the local country plug standard. The rad-D will
automatically adjust to the power supplied.
Alarm Display Panel:
Locate the Alarm Display Panel near the operator or where it can be read easily, unless your rad-D is
going to be read remotely via PC. The Alarm Display Panel must be within reach of a power plug and
within 50 feet of all detectors.
If the rad-D is integrated as part of a computer network via its wireless Bluetooth interface, the receiving
computer must be within 100 meters or less (depending on intervening walls) of the Alarm Display Panel.
If the rad-D is integrated as part of a computer network via its Serial Port interface, the receiving computer
must be connected using a single serial cable. The PC network displays rad-D information using the
provided rad-D software. The data format and structure of the interface is also available on request,
allowing the user to use create their own monitoring software.
Detector Installation Guidelines:
All detectors are mounted using two ½” screws separated by 4”. The detectors can be mounted in any
orientation. Each detector has unique placement requirements for maximum efficiency.
•Gamma Detector, Omni-directional: Place this detector as close to the traffic area as possible to
maximize its sensitivity. It can be oriented in any direction. This detector weighs approximately 8
pounds.
•Gamma Detector, Narrow Field-of-View: Aim the front of the detector at the target inspection area.
The front is the end opposite the cable interface. The front is very thin aluminum, so care must be
used to prevent dents or puncturing (neither, however, will degrade the operation of the unit. It just
won’t look as nice). The field-of-view is +/- 45º from the front. Ensure that the unit is as close as
possible to the inspection area while still getting good coverage of the field-of-view. This detector
weighs 30 lbs. Please take care when handling and mounting it to avoid injury to yourself or others.
Always use safe lifting practices when moving heavy objects.
•Neutron Detector: To maximize neutron detection, place the detector as close as possible to the
traffic area. It can be oriented in any direction. This detector weighs approximately 8 pounds.

PRM Mounting Bracket
•Detector, Following the detector
mounting guidelines, mount the
detector using the two ½” screws
with the front end of the detector
(opposite of the end with the
controller cable) being closest to
the Pan Control Adjustment Knob
(Figure 4)
•Base, The base of the PRM comes
with heavy duty earth magnet
assemblies that will hold the PRM
to a steel surface in any orientation
and with any of the rad-D configurations.
The base can also be mounted directly
to any surface by whatever means is
necessary to ensure the bracket is
securely in place and will hold the
appropriate rad-D model.
•Mounting Arm, The “L” shaped riser can be attached to the solid swing arm facing any direction. The
adjustment knob is compatible with all four sides of the solid swing arm and is used to tighten the
riser to the swing arm. It is also used to adjust the height of the rad-D from the base. The height
range is from 14” (356 mm) to 19” (483 mm).
Mounting on X-ray machines:
Typical rad-D installation on X-ray machines consist of a single narrow field-of-view gamma detector and
one-or-more neutron detectors. Because the X-ray machine can generate scatter that can be detected by
the gamma detector, to avoid false alarms please do not aim the front of the detector into the X-ray
machine.
Either aim the gamma detector at the conveyor belt coming into the X-ray machine, or leaving the X-ray
machine. Depending on the relative radiation noise from the X-ray machine (older machines tend to be
noisier), the rad-D may have to be tuned with the X-ray machine in a one-time operation to eliminate false
alarms. Inside the Alarm Display Panel is a 16-position switch that can be turned from position “0” to “15”.
From the factory the unit is set to “0”, unless requested otherwise.
If the rad-D, when mounted, is alarming as a response to the X-ray machine:
1) Unplug the rad-D
2) Open the back of the Alarm Display Panel by removing the (4) 2mm hex screws
3) Set the 16-position switch to a “1” using a small blade screwdriver
4) Close the Alarm Display Panel
5) Plug the rad-D into the wall socket
6) Check to see if the false alarm response from the X-ray machine has been eliminated.
Usually a setting of “1” is sufficient for modern X-ray machines. If there are still false alarms, adjust the
switch to a “2” using the process described above. If there are still false alarms, increase the switch one
setting using the process described until the rad-D does not have a false alarm response to the X-ray
machine.

Non-Alarming
When not alarming, the rad-D information panel displays the measured gamma counts per second and
measured neutrons per second for each detector in a repeating display cycle. If your rad-D system
consists of four gamma detectors, the display would show the gammas/second from detector #1,
indicated by the 1st LED light below the gamma count display being lit. Then the gammas/second from
detector #2 would be shown (accompanied by the second LED light being lit). The cycle would continue
with the gammas/second measured by detectors #3 and #4 being shown and then would begin again with
detector#1. A similar cycle would be shown if there were four neutron detectors. If you have a mixed
combination of gammas and neutron detectors, than the detectors would be cycled similarly to the
previous examples, except split between the gamma and neutron displays.
Alarms
During an alarm, the non-alarming detectors are no longer displayed. Instead the gamma or neutron
count of the alarming unit is displayed, with the specific detector identified by the detector number light. If
more than one gamma or neutron detector is alarming, the display shifts between the two. Both the
gamma and neutron counter displays are real-time. When the radiation source moves on, they will go
back to displaying normal levels. The Alarm Display Panel also has persistent alarm displays for gamma
and neutron alarms. These will not clear to normal levels until reset, either using the manual button on the
Alarm Display or via computer. The persistent gamma alarm displays the highest alarm level (1 through 9)
that a detector measured. The persistent neutron alarm indicates an alarm, but does not display a level
(any neutron source above natural background requires investigation).
