A
Area Investigated

An area that has been physically and systematically searched and investigated by a qualified & competent UXO clearance practitioner to ensure that all munitions and UXO, and significant components of munitions and UXO, have been located and identified.

Area Marking

The positioning of physical markers to clearly show the boundaries of the area cleared of mines, UXO, EO and explosives.

Area – Remediated

The positioning of physical markers to clearly show the boundaries of the area cleared of mines, UXO, EO and explosives.

B
Borehole Search

A method of detecting buried bombs at depths deeper than the detection capability from the surface of the magnetometer. In this method deeper detection is achieved by passing the magnetometer probe down a pattern of boreholes and taking readings every metre of depth. The readings are then collated, converted and a graph produced which shows the location, depth and attitude of any bomb detected.

D
Deep Search

A search by magnetometer down to a depth of approximately 3 metres (depending on ground conditions).

Destruction

The destruction of munitions or UXO without moving the item from where it was found.

Destruction In-Situ

The discovery, by any means, of the presence of UXO.

E
Explosive Ordnance Disposal (EOD)

All iems containing explosives, pyrotechnics nuclear fission or fusion materials, biological and chemical agents, which are dropped, placed fired or otherwise delivered in order to cause death and destruction to human beings or physical assets. It includes bombs and warheads; guided and ballistic missiles; artillery, mortar, rocket and small arms ammunition; all mines, torpedoes and depth charges; pyrotechnics; clusters and dispensers; cartridge and propellant actuated devices; electro-explosive devices; clandestine and improvised explosive devices; and all similar or related items or components explosive in nature.

Explosive Ordnance Disposal (EOD)

The detection, identification, evaluation, render-safe, recovery and disposal of Unexploded Ordnance (UXO).

Explosive Ordnance (EO)

All iems containing explosives, pyrotechnics nuclear fission or fusion materials, biological and chemical agents, which are dropped, placed fired or otherwise delivered in order to cause death and destruction to human beings or physical assets. It includes bombs and warheads; guided and ballistic missiles; artillery, mortar, rocket and small arms ammunition; all mines, torpedoes and depth charges; pyrotechnics; clusters and dispensers; cartridge and propellant actuated devices; electro-explosive devices; clandestine and improvised explosive devices; and all similar or related items or components explosive in nature.

Explosive Remnants of War (ERW)

Everything covered under the categories of Explosive Ordnance (see above) and Unexploded Ordnance (see below).

F
Free From Explosives (FFE)

A munition, UXO, item of ordnance or ordnance produce that has been inspected and determined to no longer contain explosives.

Fuse

A device that initiates an explosive or pyrotechnic process.

G
Ground Penetrating Radar (GPR)

A method of using radar waves radiated into the ground which are reflected back to the detector by solid objects. The system is more usefull for detecting things with contiguous shapes, such as pipes and cables rather than UXO. GPR does not function well where it has to pass through water.

H
High Explosives (HE)

A substance or mixture of substances which, under external influence rapidly decomposes at mollecular level and is capable of rapidly releasing energy in the form of pressure, gases, heat, light and noise.

I
Investigation

The excavation and identification of the source of a magnetic anomaly detected during the electronic investigation of the area.

L
Large Loop Detector

A deep search metal detector for the inspection of wide areas to detect medium to large sized metal objects, which correspond at least to approx 0.01% of the sensor size. The large loop detector detects ferrous and non-ferrous metals and alloys and operates on the Pulse
Induction principle. The sensor is water tight and can be operated on or in shallow water down to a depth of approx. 2 – 3m.

Layer Search

A method of searching the ground to depths deeper than the search capability of the detector used, by searching, excavating to the searched depth and then searching again. The procedure is repeated until the desired searched depth is reached.

M
Magnetometer

An instrument that measures variations in the Earth’s magnetic field caused by the presence of magnetic or ferrous objects. It usually consists of two coaxially mounted fluxgate sensors that indicates the gradient between each sensor’s variations in the magnetic field. In most instruments an audio signal alerts the operator to the presence of the object while a scaled meter provides an indication of approximate depth and size. Magnetometers are significantly more sensitive than basic Mine Detectors and, in areas of low background magnetic noise, will find more deeply buried items. Magnetometers may be analogue or digital.

Mine Detector (Metal Detector)

Mine Detectors are more correctly known as “Basic
Electromagnetic Detectors.” The detectors transmit an oscillating magnetic field that induces an opposing field into any nearby metal object. The induced opposing magnetic field is sensed and processed by the detector and is indicated by an audio tone. The depth to which a detector will find a metal object is determined primarily by the size of the object and the size of the search coil of the instrument.

Multi Sensor Towed Array Detection Systems (MTADS)

MTADS is a vehicle-towed platform equipped with an array of passive magnetic and active electromagnetic induction sensors that are used to record digitally evidence of buried UXO or other large metal objects. Advanced systems are also equipped with a Global Positioning System (GPS) to detect and map the location of buried UXO. MTADS enhances the speed of detection typically by a factor of ten compared with the Mag-and-Flag method. The system can survey 10 to 25 acres per day and provide data at high density (70,000 to 100,000 measurements per acre). The electromagnetic induction sensor detects small ferrous and non-ferrous materials.

Munition

An item of military ordnance which is placed, dropped, fired, projected or otherwise delivered, which contains explosive, pyrotechnic, nuclear, chemical or biological material designed to inflict damage on personnel or equipment or other assets.

Q
Quality Assurance

QA deals with developing processes and systems that focus on providing confidence that the quality requirements of the finished product will be met. It aims to confirm that the management and operational procedures for UXO Clearance are appropriate and will achieve the necessary outcomes.

Quality Control

The component of Quality Management that focuses on fulfilling the quality requirements of the finished product.

R
Render Safe Procedure (RSP)

The application of special EOD methods and tools to provide for the interruption of functions or separation of essential components to prevent an unacceptable detonation from occurring.

The function of the probability of the occurrence of harm and the severity of that harm.

Risk Management

The management of risk through the practices of Avoidance, Reduction, Transfer, Retention.

S
