Underwater detection of dangerous substances: status the SABAT project
The Neutron Activation Analysis (NAA) plays an exceptional role in the modern
nuclear engineering, especially in detection of hazardous substances. However,
in the aquatic environment, there are still many problems to be solved for
effective usage of this technique. We present status of SABAT (Stoichiometry
Analysis By Activation Techniques), one of the projects aiming at construction
of an underwater device for non-invasive threat detection based on the NAA
Monte Carlo N-Particle simulations of an underwater chemical threats detection system using neutron activation analysis
In this paper we present Monte Carlo N-Particle (MCNP) simulations of the
system for underwater threat detection using neutron activation analysis
developed in the SABAT project. The simulated system is based on a D-T neutron
generator emitting 14~MeV neutrons without associated particle
detection and equipped with a LaBr:Ce scintillation detector offering
superior energy resolution and allowing for precise identification of
activation quanta. The performed simulations show that using the
neutron activation analysis method with the designed geometry we are able to
identify -rays from hydrogen, carbon, sulphur and chlorine originating
from mustard gas in a sea water environment. Our results show that the most
efficient way of mustard gas detection is to compare the integral peak ratio
for Cl and H.Comment: 14 pages, 5 figure
