Glossary definition of Non Ionising Radiation

Non-Ionising Radiation is a type of energy that, when it passes through the human body, has insufficient energy to directly damage DNA. Such non-ionising radiation is common in the environment, examples being ultraviolet radiation, light, infrared radiation and radio frequency radiation.

These types of radiation can come from a number of sources, including sunlight, power-lines, electrical equipment and mobile phone systems, etc, but this radiation does not have enough energy to produce ionisation. However, non-ionising radiation is not harmless, and safe levels of exposure usually need to be defined.
