X-Rays
X-rays are electromagnetic radiation of extremely high frequency They can penetrate certain material, such as clothing or muscle, but not denser material, such as metal or bone X-rays are capable of ionisation, which cause the atoms of the material through which they pass to lose electrons. This can cause damage to human tissue, and this is why there is a risk of cancer associated with X-ray radiation
