Lost in transit over two weeks ago, the button-sized silver capsule was found on the roadside in the state of Western Australia The radioactive capsule was part of a gauge used to measure the density of iron ore feed from a mine in the state’s remote Kimberley region SYDNEY: Australian authorities on Wednesday found a radioactive capsule smaller than a coin that was lost in the vast Outback after nearly a week-long search involving around 100 people along a 1,400 kilometers (870 miles) stretch of highway, officials said. The cesium-137 capsule lost in transit more than two weeks ago was discovered when a vehicle traveling at 70 km per hour (43 mph) equipped with specialist detection equipment picked up the radiation, according to officials from the state of Western Australia. The search team then used portable detection equipment to find the capsule, which was located about 2 meters from the side of the road in a remote area far from any community, they added. The radioactive capsule was part of a gauge used to measure the density of iron ore feed from Rio Tinto’s Gudai-Darri mine in the state’s remote Kimberley region. The gauge was being taken to a facility in the suburbs of state capital Perth — a distance further than the length of Great Britain. Rio was willing to pay for the cost of the search if asked by the state government, iron ore division head Simon Trott told reporters. “Of course the simple fact is this device should never have been lost,” he said. “We’re sorry that that has occurred and we’re sorry for the concern that that has caused within the Western Australian community.” People had been told to stay at least five meters (16.5 feet) away if they spotted the capsule, because exposure could cause radiation burns or radiation sickness. However, driving past it was believed to be relatively low risk, akin to taking an X-ray. ’Needle in the haystack’ Western Australia’s Emergency Services Minister Stephen Dawson said the find was an “extraordinary result” after a search involving the state’s emergency response department, defense authorities and radiation specialists. “When you consider the scope of the search area, locating this object was a monumental challenge, the search groups have quite literally found the needle in the haystack,” he said. A 20-meter exclusion zone has been set up around the capsule while defense force members verify it via a serial number. It will then be placed in a lead container and stored overnight at a secure location in Newman, a mining town roughly 1,200 km (745 miles) north-west of Perth, before being taken to the state capital on Thursday. The silver capsule, 6 mm in diameter and 8 mm long, contains cesium-137 which emits radiation equal to 10 X-rays per hour. https://www.arabnews.com/main-category/media
