A mining giant has apologised after a radioactive capsule went missing during a 1400 km journey in Western Australia. The capsule, which was being transported from the Ranger Uranium Mine to the city of Darwin, is believed to have been lost somewhere along the route.

Authorities have issued a health warning and a search is underway to locate the capsule. According to the Australian Radiation Protection and Nuclear Safety Agency, the capsule contains a small amount of uranium-235 which could pose a health risk if it is left unchecked.

Rio Tinto, the mining giant responsible for the capsule, has apologised for the incident and is working with the authorities to locate the capsule. They have also reassured the public that the risk posed is low and that their safety is their top priority.

India Today has reported that the search is ongoing and authorities are asking anyone who may have come across the capsule to contact them.

The Washington Post has reported that the capsule is believed to have been lost somewhere in the Western Australian outback, and that the search is ongoing.

This is a developing story and more information will be released as it becomes available.
