ionizing radiation

Atom-altering energy waves

Ionizing radiation is energy that can knock electrons from atoms, creating charged particles (ions).

It includes X-rays, gamma rays, and emissions from radioactive materials.

Ionizing radiation damages living tissue and DNA, causing radiation sickness at high doses and increasing cancer risk over time.

It's distinguished from non-ionizing radiation like radio waves or visible light, which lack sufficient energy to ionize atoms.
