Authorities say they were always "confident" they were going to find a Tic Tac-sized radioactive capsule that sparked a frantic search after it "fell off the back of a truck" in Western Australia's outback.
The tiny capsule, which was found Wednesday after being lost somewhere along a 1,400-kilometre journey between a Pilbara mine site and a depot in Perth's north, arrived in Perth on Thursday evening.
No chances were being taken with the transport of the 6mm-by-8mm capsule after its remarkable recovery, with it being escorted by 14 personnel from the Department of Fire and Emergency Services (DFES), the Australian Defence Force, and personnel from the Australian Nuclear and Science Technology Organisation to a top-secret facility.
