4 giorni fa · Technically, we too are radioactive, as our bodies have very trace amounts of the radioactive isotopes of potassium and carbon. Radioactivity is everywhere, and life forever remains indebted to it for keeping our Earth’s core broiling and ensuring that we are protected under a cozy magnetic bubble.

È ritenuto il più grave incidente della storia dell'energia nucleare e l'unico, insieme a quello di Fukushima del 2011, a essere classificato al settimo livello, il massimo, della scala di catastroficità INES.
1 giorno fa · Use in space. The multi-mission radioisotope thermoelectric generator (MMRTG), used in several space missions such as the Curiosity Mars rover. The most common use of nuclear power in space is the use of radioisotope thermoelectric generators, which use radioactive decay to generate power.
