Fossil fuel emissions threaten to reduce radiocarbon dating reliability

By - July 22, 2015

Radiocarbon dating is one of the great tools of science that has allowed archeologists to shed new light on everything from the building of Stonehenge to the beginnings of international trade. However, a new study from the Imperial College London suggests that fossil fuel carbon emissions may be so diluting radioactive carbon isotopes that within decades it will difficult to differentiate between modern artifacts and those over a thousand years old.

Newly-discovered waste-eating bacteria could help in nuclear waste disposal

By - September 10, 2014
"Extremophile" bacteria have been found thriving in soil samples from a highly alkaline industrial site in Peak District of England. Although the site is not radioactive, the conditions are similar to the alkaline conditions expected to be found in cement-based radioactive waste sites. The researchers say the capability of the bacteria to thrive in such conditions and feed on isosaccharinic acid (ISA) make it a promising candidate for aiding in nuclear waste disposal. Read More

Graphene oxide causes radioactive material to "clump" out of water

By - January 12, 2013 2 Pictures
Removing radioactive material from contaminated water, such as that in Japan’s Fukushima nuclear power plants, could be getting a little easier. Scientists from Houston’s Rice University and Lomonosov Moscow State University have discovered that when flakes of graphene oxide are added to such water, it causes the radionuclides to condense into clumps. Those clumps can then be separated and disposed of. Read More

Capsule removes radioactive substances from beverages

By - March 29, 2012 3 Pictures
With airborne radioactivity from Fukushima's still-critical damaged reactors circling the globe and more likely on the way from the mass incineration of earthquake debris, individuals are certainly justified in wanting to shield themselves from the fallout, especially when it shows up in their food and drink. Now, to address concerns about nuclear contamination in juice, milk and even water, a team of researchers led by Allen Apblett from Oklahoma State University (OSU) has announced development of a capsule that, when dropped in liquid, can easily and effectively remove numerous radioactive substances and thus prevent the consumer from ingesting them.
