"Radioactive" is a song by English rock band The Firm. It was the first single released from their eponymous début album The Firm, where it was the fifth track. It was written by Paul Rodgers. A compact and straightforward rock song from the 1980s, structured with Tony Franklin's fretless bass hook at the beginning, combined with Jimmy Page's guitar scratch on the third line in the verse, Rodgers' reverbed vocal, and followed by a wah pedal inflected guitar solo. Chris Slade plays a steady drum beat throughout. On live performances, the song was introduced with a drum solo from Slade, leading into Franklin's opening bass line. Page utilized his brown 1960s Fender Telecaster guitar featuring a Parsons and White B-string bender on tour with this song.
