Stalagmites' nuclear touch a record of climate change
Richard Macey, The Sydney Morning Herald
RADIOACTIVE fallout from nuclear bombs detonated in the atmosphere more than 50 years ago has been found far underground, in limestone cave stalagmites around Australia.
This time the fallout is serving humanity, helping scientists understand climate changes over the past 500,000 years.
Seeking ways to map past climate patterns, researchers from the Australian National University, Newcastle University and the Australian Nuclear Science and Technology Organisation proposed harnessing stalagmites as ancient rain gauges.
