The Potassium Decay (KDK) Collaboration used the KDK array to detect a previously unmeasured process in the radioactive decay of potassium-40 to argon-40 involving a rare type of electron capture.

Bananas are naturally radioactive due to potassium-40, a common isotope found in nature. While this might sound alarming, it's a harmless fact. Humans are actually more radioactive than bananas, and ...

San Francisco - Radioactive potassium, common enough on Earth to make potassium-rich bananas one of the "hottest" foods around, appears also to be a substantial source of heat in the Earth's core, ...

Researchers from KDK Collaboration at the Holifield Radioactive Ion Beam Facility of Oak Ridge National Laboratory recently made the first direct observations of rare decay processes, such as K-40 ...
