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.

Bananas, though radioactive due to potassium-40, don't pose health risks. The radiation from one banana is minimal compared to daily exposure from various sources. Interestingly, humans are more ...

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 ...

There’s a small problem with Earth’s magnetic field: It should not have existed, as Earth’s rock record indicates it has, for the past 3.5 billion years. Motions in the Earth’s molten iron core ...
