Paragraph 1
A radiation
was issued in Australia on Saturday over a missing radioactive capsule. The warning was from
in Western Australia. State officials there warned residents of a "radioactive
risk" in several
, including the state capital Perth. The search is now on for the tiny capsule, which contains the
and radioactive substance Caesium-137. The capsule is just 8 mm high and 6 mm
. However, it contains a sufficient
of radioactive material to "cause serious health consequences". The capsule went missing as it was being transported from the mining
