Australia’s nuclear safety agency said on Tuesday it had joined the hunt for a tiny radioactive capsule missing somewhere in the outback, sending a team with specialised car-mounted and portable detection equipment. Authorities have now been on a week-long search for the capsule which is believed to have fallen from a truck that had travelled some 1,400 kilometres (870 miles) in Western Australia. The loss triggered a radiation alert for large parts of the vast state.
