Here is the equation for the alpha decay of radon-219 into polonium. Beta decay involves the conversion of a down quark to an up quark. This changes a neutron into a proton plus an electron.

Experimental observations of the half life of rutherfordium-252 demonstrate that its stability lies well within the limits required for full atoms to form ...

A team of researchers from GSI/FAIR, Johannes Gutenberg University Mainz, and the Helmholtz Institute Mainz has succeeded in ...

“Libby’s method remained the only way to measure carbon-14 in samples for several decades and was long considered the most accurate means of dating carbon decay,” said David Mazziotti, a UChicago ...
