A possibility for standoff bomb detection

Abstract

The response functions of backscattered photons, which are initially collimated with an energy of 662 key, were obtained by a Monte Carlo method in an NaI(TI) scintillation detector using a suitcase or briefcase full of paper, clothing, ammonium nitrate or other generic explosives, as these can be used for terrorism. The results show that characteristic response functions for ammonium nitrate and generic explosives may be found, and using this information, standoff detection of these materials may be possible.
