- P3 1.1- X-Rays
- X-Rays can cause cancer but can also treat cancer
- X-Rays are used in hospitals to make images and CT scans and to destroy tumours at or near the body surface
- X-Rays can damage living tissue when they pass through it
- This is called ionisation
- X-Rays are absorbed more by bones and teeth than by soft tissue
- X-Rays are part of the electromagnetic spectrum
- They have a high frequency
- They have a very short wavelength
- Charge- coupled devices (CCDs) can be used to form electronic images of X-Rays
