High
Ionisation - 26What are the properties of X-Rays?They affect a photographic film in the same way as light. They are absorbed by metal and bone. They are transmitted by soft tissue.
- 27What can X-Rays be used for?Diagnose some medical conditions, for example in computed tomography (CT) scanning, bone fracture and dental problems. X-Rays are also used to treat some conditions, for example in killing cancer cells.
- 28Use of high energy ionising radiation can be _________.Dangerous, precautions need to be taken to monitor and minimise the levels of radiation that people who work with it are exposed to.
