The radioactive capsule on the centre of a close to week-long search alongside a 1200km stretch of nation highway didn’t contaminate the realm the place it was discovered.
The capsule was discovered on Wednesday morning simply off Great Northern Highway, about 74km south of the mining city of Newman.
It’s believed the capsule fell off a semi-trailer because it was being transported to Perth earlier in January.
The location of the capsule would point out it wasn’t far into its journey from Rio Tinto’s Gudai-Darri mine web site north of Newman to the Perth northern suburb of Malaga.
The Australian Defence Force, together with consultants from the Australian Nuclear Science and Technology Organisation, arrange a 20m “hot zone” across the capsule.
Western Australia’s Department of Fire and Emergency Services stated subsequent testing on the web site has revealed no residual contamination from the capsule, and “there was no need to remediate the area.”
The capsule itself, which is sufficiently small to suit on a 10c coin, was positioned in a lead-lined case for transport to Perth on Thursday as investigations into the way it grew to become misplaced proceed.
The capsule, containing radioactive materials Caesium-137, was utilized in mining gauges to measure the density of iron ore.
It’s speculated the vibration of the semi-trailer used to move the gauge one way or the other knocked the capsule free.
The actual method through which it fell from the truck will kind a part of a WA authorities investigation.
In a press release on Wednesday, Rio Tinto stated it was conducting its personal investigation into the incident, and has expressed its gratitude to all of the businesses concerned within the six day search.
