The blast is what people imagine. A sudden flash, a rising cloud, the moment when history splits into “before” and “after”. Nuclear disasters and atomic weapons ...

The nuclei of certain atoms are stable and under ordinary circumstances, stable nuclei do not undergo change. The nuclei of other atoms are unstable. These nuclei undergo change spontaneously, that is ...

A surprising glow from radioactive rocks can spark curiosity about the science behind radiation and natural minerals. This moment explores what may cause certain radioactive rocks to emit visible ...

Wild boars have become so radioactive that German hunters aren’t even bothering to pursue them anymore. And while the prevailing theory has been that the Chernobyl nuclear plant meltdown in 1986 is ...

Free-roaming boars in the woods of Austria and Germany have levels of radioactivity that makes their meat unsuitable for eating. Once thought to be the result of the Chernobyl nuclear power plant ...
