HJ4/9] There are three non destructive radiological methods for identitication of warfare agents and TNT. Their principles and problems related were discussed. Portable isotopic neutron spectroscopy is based on the assay of key elemental composition (such as Cl, P, H, As, S, N) in chemical agents by neutron induced prompt gamma ray analysis. Hydrogen concentration measurement by means of using thermal neutron can be exployed to identify chemical warfare agents and TNT that contains different hydrogen fraction. The calibration curves of thermal neutron count rate against hydrongen concentration were measured. X ray imagination system can be used to determine the internal structure of chemical bombs, thereby to identify them. The radiological methods are very useful for identification of old chemical weapons abandoned by Japan Army during World War 2.
