Sometime between 10 and 16 January 2023, a radioactive capsule containing caesium-137 was lost from a truck in Western Australia.

The Department of Fire and Emergency Services announced to the public on 27 January that the capsule had gone missing, and that the capsule was potentially deadly and could cause burns and radiation sickness. It was discovered on the side of the road near Newman on 1 February.
