Radioactive Records was an American record label. It was formed as a joint venture between talent manager Gary Kurfirst (who managed such acts as the Ramones, Big Audio Dynamite, Deee-Lite and Deborah Harry) and MCA Records, and it is now out of business. In 1997, Kurfirst formed a related label, Radiouniverse, as a joint venture with Universal Music Group's Universal Records. It debuted with albums from Radio Iodine and Dig, bands that were formerly signed to Radioactive. Other acts signed to the label included The Devlins and Tyzle Fly.
