Question 1

On an X-ray image, organic materials such as food and plastic typically appear in which color?

Accepted Answer

Orange or amber

Organic materials have low atomic density and appear orange or amber on standard X-ray color displays.

Question 2

A bag shows a dense, irregularly shaped white mass surrounded by wiring. What is the MOST appropriate first action?

Accepted Answer

Alarm the lane and call for a supervisor or EOD

Answer

A dense mass with associated wiring is an IED indicator requiring immediate escalation to a supervisor or explosive ordnance disposal team.

Question 3

Which X-ray feature best helps distinguish a firearm from similarly shaped metal objects?

Accepted Answer

The characteristic shape including barrel, trigger guard, and grip outline

Answer

Firearms have distinctive outlines—barrel, trigger guard, and grip—that remain recognizable even at different orientations.

Question 4

What does the term 'superimposition' mean in the context of X-ray image interpretation?

Accepted Answer

Multiple items overlapping, making individual objects harder to identify

Answer

Superimposition occurs when objects stack on top of each other in the image, obscuring details and making threat identification more difficult.

Question 5

A TSO notices a laptop-sized object that displays as a solid, uniformly dark rectangle with no internal components visible. This should raise suspicion because:

Accepted Answer

Legitimate laptops show complex internal components such as batteries and circuit boards

Answer

A genuine laptop displays internal structures; a featureless dense block may indicate a concealed threat or modified device.
