Radioactiva was a Venezuelan radio station launched in 1995. It primarily focused on rock and alternative music, becoming a cultural reference for younger audiences during its time. The station was part of the Unión Radio network and operated on the FM band in major cities like Caracas (90.5 FM). It ceased operations in 2006 when its frequency was repurposed for the adult contemporary station Éxitos FM. Radioactiva is remembered for promoting local rock bands and hosting music-related events.
