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