UXO Location using Total Field Magnetics in SE Asia

Abstract

Unexploded Ordnance (UXO) is a major problem in a large number of areas throughout the world and SE Asia is no exception. As most of the older ordnance is of ferrous composition, total field magnetics is an eminently suitable tool for its location. During the past few years work has been carried out on two major infrastructure development projects in SE Asia, one being in Hong Kong and the other in Taiwan. The projects have involved the use of tightly spaced total field magnetic traverses to locate buried UXO. The located items were then removed to allow for safe operations on the sites. Both sites were intended for public access and thus required a high level of confidence that no UXO remained buried on site. Both clients have adopted the results of the survey as an approved methodology for the location and removal of buried UXO.
