Image 1. Typical set-up for portable radiography
ׁ HINT. Often with IEDD radiography equipment the bottom of the suspect object is missed from the image. This is due to the image capture plate being set on the same flat surface as the suspect object and X-ray generator. When appropriate, the item to be X-rayed can be raised slightly so a complete image can be taken.
ׁ WARNING. IEDD operators must observe the evacuation area associated with the use of X-ray generators. This will be defined in the manufacturer’s user guide.
STEP 3 – ANALYSIS AND INTERPRETATION
ׁ HINT. A common occurrence is a tendency to focus on what is already known about the IED components, rather than conducting a thorough systematic evaluation. It is likely that cross referencing with other IEDD operators and team members, with structured and constructive discussion, is likely to help mitigate this issue.
A radiograph is only as effective as the analysis and interpretation of the produced image. It is important that IEDD operators have the appropriate knowledge, skills and attitudes (KSAs) in accordance with T&EP 09.31/01/20. This includes detailed knowledge of IED tactics and construction procedures which will aid in radiograph analysis and interpretation.
ׁ HINT. To aid in the identification of components on a radiograph image, IEDD operators can learn by taking radiographs of known IED components in different planes to see how they are displayed.
