ICRPAEDIA: Effects of Exposure to Radiation


For the purposes of radiological protection, harmful effects of radiation exposure are grouped into two categories:

Deterministic Effects

Stochastic Effects

Effects, such as skin burns, that only appear at relatively high doses.

Effects, such as cancer, that are assumed to pose some risk even at low doses.

▶ In more detail

The United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) is the leading international body on radiation levels and effects. Visit the UNSCEAR website or read the UNEP report on "Radiation Effects and Sources" based on UNSCEAR work to learn more.
