What is the immediate consequence of x-ray absorption in tissue that leads to biologic damage?

When tissue absorbs x-ray energy, it ionizes molecules, especially water, creating free radicals. These reactive species drive chemical changes in biomolecules such as DNA and cell membranes, which leads to cellular and tissue damage. In diagnostic radiography, the damage is dominated by these chemical changes rather than heat, since the energy deposited is not enough to cause meaningful thermal heating. Tissue does not become radioactive after exposure, so there’s no persistent radioactivity.
