An environmental group is touring the South Australian outback this week to observe the impact of uranium mining on the environment.
Friends of the Earth has been making the trip around mine sites almost every year since 1983.
Nuclear campaigner Jim Green says the group appreciates being shown mine sites such as Olympic Dam and Beverley, despite its presence causing tension.
Dr Green says it is important to regularly observe what happens around a mine.
"Over the years we've taken many, many people out to the South Australian desert to see first-hand the impacts of the uranium mining industry," he said.
"So it's really important and of course with a long-term project like this one, going over 30 years, you get to witness long-term impacts that you otherwise wouldn't."
He says tours in recent years have included a presentation by a Maralinga veteran about nuclear weapons testing.
"There are those social impacts on the veterans of the nuclear bomb tests and we'll also be speaking to Aboriginal traditional owners who are involved in debates about uranium mining, that's at Roxby Downs and also at the Beverley mine," he said.
