Advanced discrimination methods and careful optimization of operational procedures are critical for efficient remediation of unexploded ordnance (UXO) contaminated sites. In this paper, we report on our experiences with a 200 acre magnetic survey that was collected and processed under production survey conditions at Chevallier Ranch, Montana. All anomalies with fitted moments above 0.05 Am were...

Military activity has resulted in unexploded ordnance (UXO) existing the nearshore. Understanding and predicting UXO behavior is important for object identification, management. Here, two studies (laboratory fieldwork) have been conducted to observe surrogates swash zone relate burial migration underlying forcing conditions. A small-scale laboratory dam-break study was quantify of varying densi...

During the World War I ,II over fifty countries in the world today have been inherited a legacy of antipersonnel landmines and unexploded ordnance (UXO) which represents a major threat to lives, and hinders reconstruction and development efforts. Landmines have specific properties that make it harder to detect .Therefore; these properties lead landmine detectors to become more complex. Many exa...

Portable transient electromagnetic (TEM) systems can be well adapted to various terrains, including mountainous, woodland, and other complex terrains. They are widely used for the detection of unexploded ordnance (UXO). As the core component of the portable TEM system, the sensor is constructed with a transmitting coil and a receiving coil. Based on the primary field of the transmitting coil an...

A 200 acre magnetic survey was collected and processed under production survey conditions over a site in Montana contaminated with unexploded ordnance (UXO). All anomalies with fitted moments above 0.05 Am2 were excavated. During the survey the magnetic remanence metric was predicted but not used to guide the discrimination. The retrospective analysis presented here reveals that discrimination ...

SUMMARY We investigate if it is theoretically possible to discriminate between unexploded ordnance (UXO) and non-UXO sources by modelling the magnetic dipole moment for ferrous objects of different shapes sizes. This carried out approximating volumetric demagnetization factors rectangular prisms, representing similar a long rod or flat steel plate. By UXO as prolate spheroids can be determined ...

The goal of the work presented in a two-companion paper is to pave way for reliably assessing risks damage buildings on shore, induced by detonation unexploded historical ordnance (UXO) large weights variable shallow water environments with depth less than 50 m. risk assessment quantified through seismic magnitude Richter scale, charges different (between 80- and 680-kg TNT-equivalent). This me...

It is proposed to use 14 MeV neutrons tagged by the associated particle neutron time-of-flight technique (APnTOF) to identify the fillers of unexploded ordnances (UXO) by characterizing their carbon, nitrogen and oxygen contents. To facilitate the design and construction of a prototype system, a preliminary simulation model was developed, using the Geant4 toolkit. This work established the tool...

DRDC Valcartier is actively working on the assessment of the extent of energetic materials contamination on Canadian DND training ranges. This work is carried out with the objective of creating sustainable training conditions for the Canadian Forces. As part of this effort, research is being undertaken to study, in laboratory conditions, the leaching of explosives from cracked or opened munitio...

The focus of this paper is effective health education and promotion in the field of mine awareness, or what has more recently been re-titled 'mine risk education'. According to the United Nations, mine risk education comprises educational activities that aim to reduce the risk of injury from landmine/unexploded ordnance (UXO) through raising awareness and promoting behavioural change and includ...
