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.
