  • Australian officials on Wednesday recovered a powerfully radioactive container that was lost in the desert.
  • 2
  • Officials said a team found the small container, or capsule, after days of searching, involving about 100 people along 1,400 kilometers of highway.
  • 3
  • The capsule is smaller than a coin, a piece of metal money.
  • 4
  • The capsule contained Caesium-137, a highly radioactive material.
  • 5
  • It was lost while being transported more than two weeks ago.
  • 6
  • A vehicle equipped with special detection equipment picked up the radiation from the capsule, officials from the state of Western Australia said.
  • 7
  • The search team then used smaller detection equipment to find the capsule itself.
  • 8
  • It was about two meters from the side of the road in an area far from any community, officials added.
  • 9
  • The mining company Rio Tinto used the radioactive capsule to measure the density of iron ore in the Gudai-Darri mine in the Australian state's remote Kimberley area.
  • 10
  • Rio Tinto was sending the capsule to a center near the state capital, Perth.
  • 11
  • The distance from Kimberly to Perth is greater than length of the Island of Great Britain.
  • 12
  • Simon Trott, the head of iron ore for Rio Tinto, said the company would pay for the cost of the search if asked by the state government.
  • 13
  • "We're sorry that that has occurred and we're sorry for the concern that that has caused within the Western Australian community," he said.
  • 14
  • Australians had been told to stay at least five meters away if they saw the capsule.
  • 15
  • Exposure to radiation could cause radiation burns or sickness.
  • 16
  • But, driving past was said to be low risk.
  • 17
  • Western Australia's Emergency Services Minister Stephen Dawson said the discovery was an "extraordinary result."
  • 18
  • The search involved the state's emergency response department, defense officials and radiation experts.
  • 19
  • People are not permitted to go within 20 meters of the capsule while defense officials confirm it through a serial number.
  • 20
  • It will then be placed in a lead container and kept in a secure place in Newman.
  • 21
  • Newman is a town about 1,200 kilometers north-west of Perth.
  • 22
  • It will be taken to the state capital on Thursday.
  • 23
  • The capsule is only six millimeters across and eight millimeters long.
  • 24
  • But, it contains Caesium-137.
  • 25
  • The small amount can release radiation equal to 10 X-rays every hour.
  • 26
  • Officials said the capsule fell off a truck and landed on the side of the road.
  • 27
  • Officials added that it was unlikely contamination in the area would be a problem.
  • 28
  • Rio Tinto said in a statement that it would investigate whether it should have hired specialist contractors.
  • 29
  • SGS Australia prepared the capsule and Centurion transported it.
  • 30
  • Centurion said it is investigating how the capsule fell off the truck.
  • 31
  • The container provided by SGS arrived in Perth in the same condition in which it was sent.
  • 32
  • Technical GPS information showed the truck did not suddenly change speed.
  • 33
  • Western Australia's Chief Health Officer Andrew Robertson said there would be an investigation.
  • 34
  • He said officials would consider charges under the state's radiation safety laws from 1975.
  • 35
  • The highest fine for failing to safely deal with radioactive substances is about $700.
  • 36
  • The state government said on Wednesday it was considering a change to permit bigger fines.
  • 37
  • But officials said they may not use new laws against Rio Tinto for this incident.
