Edited sentence: Environment Australia (an agency of the Government of Australia) have documented over 200 environmental incidents.Similar faults occur almost every year, however they are usually caught sooner.The court heard detailed evidence surrounding accidental radiological exposure to ERA employees.There have also been incidents when vehicles left the mine site without complete decontamination.These ongoing concerns have compounded as the volumes of radioactive waste being managed on the site grow, culminating in May 2005 in an historic conviction for breach of their environmental guidelines - the first such prosecution of a mining company in the Northern Territory.Two of these had been insufficiently cleaned but authorised to leave, and a third had not been cleaned or cleared to leave.When radiologically contaminated process water contaminated the drinking water supply, some workers drank and washed in the contaminated water
