Question
X-rays are used in hospitals for computed tomography (CT) scans. (i) State one other medical use for X-rays. ______________________________________________________________ ______________________________________________________________(1) (ii) State a property of X-rays that makes them suitable for your answer in part (d)(i). ______________________________________________________________ ______________________________________________________________(1)
Solution
(i) Apart from CT scans, X-rays are also used in hospitals for radiography. This includes routine check-ups, diagnosis of broken bones, infections, locating foreign objects in the body, and detecting lung conditions like pneumonia or lung cancer.
(ii) One property of X-rays that makes them suitable for radiography is their ability to penetrate soft tissues and be absorbed by denser materials. This allows for the creation of contrast images where bones and foreign objects appear white against a black background of softer tissues and empty spaces.
