Detection of explosives in objects on the bottom of the sea

Several tests have been done with the neutron generator incorporated inside a small submarine equipped also with a few other sensors like video cameras and a magnetometer. Following the detection of an anomaly on the sea bottom a neutron sensor is requested to check for the presence of explosives. In the experiment, the TNT explosive was measured behind an iron shield. Comparison was made with similar measurements when the TNT explosive was replaced by stones. By measuring the C/O ratio the TNT explosive was successfully identified. All the measurements were done first in air and after that repeated in freshwater and in sea water.
