Fast Neutron Activation Analysis System Customized for the Non-destructive Identification of Explosives and Chemical Warfare Agents (CWAs).

Applications

• Main Application: Chemical Warfare Agent and Explosive Identification by Neutron Activation Analysis (NAA)
  Neutron induced gamma spectroscopy is used for the detection of explosives and chemical warfare agents in ammunition such as bombs and shells without container opening with the risk of CWAs emission.
  Other applications:
• trace element "fingerprinting"
• control of gold slugs and gold containing materials
• detection of components of metals and alloys
• detection and control of nuclear material content
• ecological monitoring of environment, control of agriculture production
• detection of poison and other toxic substances without container disclosure

• A pulsed neutron generator, based on Deuterium – Deuterium reaction, which does not emit radiation if switched off, is used as the source.
• Reactions of neutrons with the contents of shells result in substance specific gamma emission which are characteristic for the elements and their identification.
• In contrast to explosives, chemical warfare agents contain the key elements chlorine, arsenic, sulfur, phosphorus and fluorine which allows to differ them.
• This method is well suited for the detection of any chemical warfare agent; old ones produced during the World War I and World War II well as for modern chemical agents.

Pulsed Neutron Source
The pulsed neutron generator is easy to transport and radiation protection is only needed during analysis time.

Detection system
Electrically cooled HPGe-detector with high efficiency fast signal progressing unit.

Computer
PC with software for the control of neutron generator, detector and ammunition holder; and software for data evaluation and substance identification.

Ammunition holder
Preprogrammable adaptor for all types of shells.
