Is that above or below the danger level? Oh, electrical conductivity? Kakadu national park is now contaminated for the next 100 million years - or more. What a disaster.

In 2010, millions of litres of radioactive water from the Ranger uranium mine flowed into Kakadu’s wetlands.

The Traditional Owners opposed then plans for a huge expansion of the 30 year old mine by ERA. At the time, the ERA attempted to downplay a spike in contaminated water flowing from the Ranger to Kakadu’s Magela Creek between April 9 to 11. 40 Aboriginal people lived downstream from the site where a measure probe recorded up to five times the warning level of electrical conductivity – including uranium, sulphate and radium contaminants.

“As more of our people understand the death knell dangers of uranium mining we will then come together in greater numbers and we will close down Ranger and Olympic Dam,” said Mr Buzzacott.

By radioactivity from: uranium, sulphate and radium contaminants.

http://www.world-nuclear.org/information-library/nuclear-fuel-cycle/mining-of-ur...

The uranium orebody contains both U-235 and (mostly) U-238. About 95% of the radioactivity in the ore is from the U-238 decay series. This has 14 radioactive isotopes in secular equilibrium, thus each represents 7% of the total. (In the case of Ranger ore – with 0.3% U308 – it has about 450 kBq/kg, so irrespective of the mass proportion, 32 kBq/kg per nuclide in that decay series.) When the ore is processed, the U-238 and the very much smaller masses of U-234 (and the U-235) are removed. The balance becomes tailings, and at this point has about 86% of its original intrinsic radioactivity. However, with the removal of most U-238, the following two short-lived decay products (Th-234 & Pa-234) soon disappear, leaving the tailings with a little over 70% of the radio-activity of the original ore after several months. The controlling long-lived isotope then becomes Th-230 which decays with a half life of 77,000 years to radium-226 followed by radon-222.

They are probably using conductivity as a cheap way to measure radioactivity.

Yes - a set of Geiger counter measurements would be better.

I am sure they have done that too & probably a scintillation counter
to measure the actual isotopes.
