Missing radioactive capsule in Australia turns up on remote road

These are the dangers of a lost radioactive capsule in Australia 2:33 (CNN) -- A small radioactive capsule Missing in Australia After a challenging search like finding a needle in a haystack, she was found on the side of the road.

Officials in the state of Western Australia announced the discovery on Wednesday afternoon, six days after the capsule was found missing from a parcel sent from a mining site in the state's north to the state capital, Perth.

Authorities believe the capsule, containing highly radioactive cesium-137 material, somehow fell off the back of a truck as it was transported 1,400 kilometers (870 miles) along the Great Northern Highway.
