"Radioactive" is a song by American rock band Kings of Leon, and was the first single released from their 2010 album Come Around Sundown.

The song, along with its accompanying music video, premiered on September 8 on the Kings' website.

The video that was made in a sepia-tone refers to the band's origins, with a Southern rock sound.

Drummer Nathan Followill said, "Gospel music was a big part of us growing up, so to be able to come back and revisit that part of our lives at this stage in our lives is a pretty special thing.

[5][6] On November 25, 2010, the band gave a mini-concert in New York for The Today Show during which they performed a three-song set including "Radioactive".
