This book describes the current state of the art in chemical sensing of explosives. Beginning with a broad view of the need for and potential applications of chemical sensing, it considers the issue as one of systems engineering: how to effectively include chemical sensing in the suite of technologies incorporated into systems designed to find hidden explosive devices. It describes recent efforts to develop such sensors and offers some comparisons of strengths and weaknesses of those technologies. The book also contains a chapter on the chemistry of explosives and one on the environmental fate and transport of the molecules being sought and includes discussion of field experience using chemical sensors.

Ronald L. Woodfin is a retired systems engineer from Sandia National Laboratories, where he was "Principal Member of the Technical Staff". Much of his research while at Sandia concentrated on techniques related to mine warfare and humanitarian demining. He has served on several National Research Council Committees, including the Committee on Review and Evaluation of the Army Non-Stockpile Chemical Material Disposal Program and the Committee on Mine Warfare Assessment of the Naval Studies Board.
