An urgent search is under way in Western Australia after a tiny capsule containing a radioactive substance went missing.
The casing contains a small quantity of radioactive Caesium-137, which could cause serious illness if touched.
It was lost between the town of Newman and the city of Perth in mid-January - a distance of roughly 1,400km (870 miles).
The public has been warned to stay away from the capsule if they see it.
It was being transported on a truck between a mine site north of Newman in the Pilbara region and the north-eastern parts of Perth between 10-16 January when it was mislaid. Caesium-137 is a substance commonly used in mining operations.
The Department of Fire and Emergency Services (DFES) has said the capsule cannot be weaponised but could cause radiation burns and have other longer-term risks like cancer.
The object emits a “reasonable” amount of radiation, Dr Andrew Robertson, the state’s chief health officer and Radiological Council chair, said.
“Our concern is that someone will pick it up, not knowing what it is,” he said. “They may think it is something interesting and keep it, or keep it in their room, keep it in their car, or give it to someone.” - BBC
