THE CHALLENGE OF DETECTING AN IED

As IEDs can be composed of a huge range of different components, and their appearance is often well concealed, it is much harder for them to be identified by sight. Vidisco’s portable X-ray solutions allow a bomb squad to detect all three types of IED, regardless of how the device is made.

There are three types of IED, based on the way they are detonated:

1. TIME IED
An IED in this category utilizes a ‘time switch’ – a device which creates a countdown until detonation. This could involve the use of a simple solution, such as a mechanical or digital clock. In more creative cases, an imaginative bomber could use an unusual method, such as two electrical contacts separated by ice, which will melt, leading to the contacts touching and the bomb exploding.

2. COMMAND IEDs
These IEDs are operated by the bomber. They can be either tethered, or non-tethered. A tethered IED has a physical connection to the bomber – this could be a simple household object like the cord of a lamp, a fishing wire, or another kind of pull string. A non-tethered connection is remoted controlled, also known as an RCIED (remote-controlled improvised explosive device). The bomber could use a cell phone, Wi-Fi connection, cordless phone, key fob, or any other similar device.

3. VICTIM-OPERATED IED
The most common of the IED types, a victim-operated bomb is designed to explode when activated by the victim. Once again, creativity is the limit here, and many unconventional components may be used to trigger detonation. Suspicious findings may include a micro switch, pressure switch, trip line, or passive infrared sensor (PIR).

EXPLORING IED EXAMPLES

The following example is one that was successfully detected using a Vidisco portable X-ray system. This setup, as shown in the first image, is comprised of the two IEDs, both embedded in the same slider car door.

The first IED is a remote-controlled (RCIED) pipe bomb, with two butane bottles and a single 9V power source. The initiator is difficult to see, as it is an electric match located inside the cap of the pipe bomb. The second IED is a ‘time’ IED, utilizing an ordinary fire extinguisher which has been cut in half, and using a digital timer a switch. The power source for the device is four AA batteries. The bomb contains a quantity of C-4 explosive, with a single blasting cap as the initiator.

The Vidisco X-ray system also captured two additional images, showing the front and side view of the remote-controlled IED, which can be seen below. Thanks to the high-quality X-ray images, it’s easy to identify the threat. As the X-ray system is highly portable, and safe for use in public areas, it is suitable for deployment in situations where threats must be discovered and contained both quickly and safely.

International NDT Standards To Look For
NDTX-RAY
Non-destructive testing (NDT) is paramount for quality assurance. Used to determine the quality of pipe welding and detect defects, NDT is infinitely important to ensure suitability and safety in oil and gas pipes, aircrafts, shipyards, manufacturing equipment, and many other uses. Quality in NDT testing is of upmost importance, as anything missed in testing can lead to catastrophic consequences. For this reason, there are several international NDT standards in place that govern the quality of NDT testing methods. These standards layout appropriate methods and techniques for testing, inspection, and evaluation to ensure optimal results of NDT activities.

How NDT (DR / X-Ray) improves efficiency and safety in the oil and gas industry
NDTX-RAY
The oil and gas industry heavily relies on inspection for quality assurance, while ensuring that all equipment is running reliably and safely. With regulations such as ASME and API, oil platforms, refineries, power stations, and oil and gas pipelines must be constantly checked for corrosion, erosion, or any imperfections that could lead to dangerous conditions, critical failures, or worse, catastrophic incidents. Inspection is carried out through Non-Destructive Testing (NDT). NDT is a critical process that can be used to evaluate, analyze, and test the properties of materials without causing any harm or damage. Infinitely important for upstream and downstream oil and gas companies, NDT must be carried out efficiently and accurately to ensure smooth operation.

NDTX-RAY
Contrast-to-noise ratio (CNR) analysis is a method of evaluating contrast resolution in an X-ray image. The CNR gives evaluation results similar to those of a visual assessment. As a result, it is frequently used clinically as a physical index for image quality control, performance comparison of modalities, and quantitative evaluation of the detectability of lesions/defects.
