A tiny radioactive capsule found after two weeks in outback WA is being transported to Perth, ending a "significant public health risk".
WA’s chief health officer, Andrew Robertson, said an investigation into its disappearance has begun.
“I have responsibility as the chair of the radiological council to actually investigate and if required, prosecute offences under the act,” Robertson said.
“We have a number of authorised officers who are doing that. Our radiation health branch, within the Department of Health, is conducting that investigation and they will be looking at all aspects of this event.”
