Australians are exposed to radiation from a variety of natural and artificial sources. Radiation is energy travelling as waves or particles. Ionising radiation has enough energy to change the chemical composition of matter. Non-ionising radiation has less energy but can still excite molecules and atoms causing them to vibrate faster.
ARPANSA respectfully acknowledges the Traditional Owners and Custodians of Country throughout Australia and their continuing connection to land, waters and community. We pay our respect to Aboriginal and Torres Strait Islander Peoples, their cultures, and to Elders past, present and emerging.
