Some nuclei of certain elements decay radioactively into nuclei of different elements. These decays can be useful or annoying depending on the context. This is especially true for potassium-40. This ...

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 ...

Radioactive potassium could be a significant source of heat in the Earth's core. V Rama Murthy from the University of Minnesota and colleagues have shown that potassium-40 can exist in the core of the ...

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.
