Twin: Ionizing Radiation
Captions available
The idea
Ionizing radiation carries enough energy to knock electrons out of molecules it strikes — alpha, beta, gamma rays, high-energy UV — damaging biomolecules.
In practice
A gamma ray striking DNA can eject an electron and break a chemical bond.
Where people slip
Ionizing radiation's danger comes from breaking bonds and ejecting electrons, not merely carrying energy — confusing it with its less hazardous twin is the error.
