The HYDAD-D antipersonnel landmine detector

HYDAD (HYdrogen Density Anomaly Detection) systems have been developed to detect small (>200g) antipersonnel landmines (APM) of plastic construction. The HYDAD-D detector is based on the earlier HYDAD designs HYDAD-H and HYDAD-VM. It consists of a neutron source and two identical slow neutron detectors. The difference between the responses of the two detectors is monitored as a function of position in the minefield and APM detection is based on an analysis of this difference. Laboratory tests and Monte Carlo simulations demonstrate that HYDAD-D is capable of detecting the IAEA standard dummy landmine DLM2 at burial depths up to 23 cm, in dry sand and at burial depths up to 7cm in damp sand containing 12% (by mass) water.
