Radionuclide Fact Sheets

ARPANSA publishes a range of fact sheets about radionuclides that can be found in Australia.

Polonium-210

Australia scientists have measured natural polonium-210 in the environment to estimate how different areas of estuarine systems, seas and oceans will react to changes in climate and pollutant.

Caesium-137

Because of past nuclear weapons testing and nuclear accidents, trace amounts of caesium-137 are scattered across Australia and the world.

Americium-241

The main use for americium-241 in Australia is in household and industrial smoke detectors.

Strontium-90

Due to atmospheric nuclear weapons tests that occurred during the 1950s and 60s, some of which included testing within Australia, trace amounts of strontium-90 were dispersed throughout Australia.
