DNA damage.
Low (environmental or diagnostic) radiation exposures mainly cause molecular and cellular effects such as DNA damage (single‑ and double‑strand breaks, base damage) and mutations. Many of these lesions are repaired, but some misrepairs can increase cancer risk (a stochastic effect). Death of the whole organism is a deterministic effect that requires much higher, acute doses (whole‑body lethal doses are on the order of a few grays), not the low doses encountered in typical exposures.
