| titleOfInvention | Identification of explosives by means of rapid neutron bombardment and gamma-radiation detection as a function of time |
| abstract | A method and device for identification of explosives comprises bombarding a sample (3, Fig 3) with rapid neutrons the energy of which is greater or equal to the positron activation energy of nitrogen and greater or equal to the required energy for a neutron proton nuclear reaction of neutrons with160 to16N. The electron positron annihilation radiation, gamma radiation at 511 keV, emitted by the sample due to the neutron bombardment is detected as a function of time. Subsequently, the respective concentration and the concentration ratio of oxygen and nitrogen in the sample is determined from the time dependency of the annihilation radiation, and the explosive is identified by means of the comparison of the concentration ratios of the specific concentrations of oxygen and nitrogen with the corresponding substance ratios of known explosives. By radiation with neutrons, at the same time radionuclides13N are created from the nitrogen contained and16N from the oxygen contained, the decay of which generates electron positron annihilation radiation with characteristic half-lives. The detector may comprise a PET detector with a detector unit (2', Fig 4) on opposite sides of the sample (3, Fig 4). |
