What colors do you expect to see on an xray and what do those colors represent?
"Generally three different color shades can be seen on an x-ray film. Fatty matter and muscle appear gray. Bones and other dense materials, such as metal appear white. An example of a metal or other dense material could be if a child swallows a coin. Air in the stomach, esophagus, or lungs appears black."
Correct identification of internal structures is an essential skill of a radiographer. Structures on an xray show up with different density/shades. The interviewer wants to know that you will be able to identify what you see on an xray.
"Structures that are visible on an x-ray can include dense materials, such as bone and metal. These appear white on X-rays. Air is also detectable on an x-ray in the lungs or in the abdominal cavity. Air appears black."
