Capabilities of the Tagged Neutron (TN) method for detection and identification explosives materials (EM) are explored using an idealized geometrical model that includes a 14 MeV neutron generator with integrated alpha detector, gamma-ray detector based on BGO/LYSO crystals, irradiated samples in form simulated EM (TNT, tetryl, RDX, etc.) or benign material (BM) such as cotton, paper, etc. Research was carried out under framework computational simulations physics processes by Monte Carlo methods well experimental measurements ING-27 produced VNIIA. The work resulted comparison between measured ROC (receiver operating characteristics) curves obtained via integration analytically expressed functions irradiation time, mass, type BM. Experimental results indicate 0.3 kg tetryl simulant located 45 cm from is detected 97% cases after one minute measurement, false-alarm rate being highly dependent BM present: ∼0% case water to ∼5% silk. Comparison data these shows they agreement where account scattering object background effects.
