Rapid deployment of resonance technology
for detection and imaging of concealed
explosives, chemical warfare agents, and
dirty and nuclear bombs in shipping
containers

EDS-GRT: System Configuration
An accelerator is used to produce
protons at a specific energy such that
unique resonant gamma rays are
generated from impingement on a
specific target. The emitted gamma
rays pass through a volume of interest
and interact resonantly with specific
elements of interest so that images of
the elemental density are developed
from the variation in gamma detection
counts. Fluorescence or scattered
gammas resonant with the element are
also detected simultaneously. Non
resonant gamma rays are used to
image total density.

EDS-GRT Applications
• Current EDS systems are incapable of interrogating
large marine shipping cargo containers with any
degree of elemental specificity.
• EDS systems based on neutrons although providing
elemental specificity are highly controversial and
unsuitable for interrogating large marine shipping
cargo containers.
• There is a need for new technology to interrogate
large marine shipping and air cargo containers.

Technology

•
There is a need for new technology to meet future
needs of national security.
Configurations for various applications have been
presented, from small parcels to large cargo
containers.
Mobile capability of the system has been indicated.
The gamma source, the main obstacle of the past,
is at present commercially available.
Present objectives are; system integration,
prototype certification, and designing a deployable
system.
