New Material Traps Airborne Radioactive Elements
Scientists have come up with a technique that could make cleaning radioactive elements from the air, such as krypton, xenon and radon, easier and cheaper than current technologies. While those radioactive materials naturally mix in the air, the quantities are usually low — typically less than one part per million. The international research team from […]
New Dating System Could Reveal Secrets of Earth’s Ancient Climate
Scientists have a new tool in the quest to learn more about Earth’s ancient climate, including the mechanisms that plunged our planet into and out of ice ages. The new tool is a scientific technique called radiometric krypton dating, which recently allowed researchers to accurately determine the age of a 120,000-year-old Antarctic ice core sample. […]
