TSA CBT Practice Test

In X-ray terms, which items would appear in the green category?

1. Wires and batteries

2. Rubber and leather products

3. Organic materials and gels

4. Plastic electronic devices

The correct answer is: Plastic electronic devices

The green category in X-ray screening typically includes items that are less dense and may not be indicative of a threat. Plastic electronic devices belong in this category because they generally consist of non-metallic materials that allow X-rays to pass through more easily, resulting in a lighter appearance on the X-ray image. Objects in this category are often benign and don't raise security concerns compared to denser materials. On the other hand, wires and batteries, as well as rubber and leather products, have different densities and textures that may place them in other categories for closer scrutiny. Organic materials and gels can also exhibit properties that make them less clear in interpretation, thus falling outside the green category due to their potential to conceal items of concern.
