"Transparent Radiation" is a song by the American rock band Red Krayola released in June 1967 on their debut studio album The Parable of Arable Land. The song featured label mate and 13th Floor Elevators frontman Roky Erickson performing on harmonica.

The song would be covered by English rock band Spacemen 3 in 1987, whose version peaked at number 29 on the UK Indie Chart in 1987.

The song was recorded on April 10th, 1967, Roky Erickson of the 13th Floor Elevatorswas invited to play harmonica:

When we had the backing tracks, Roky Erickson of the 13th Floor Elevators was invited in to play the organ part on 'Hurricane Fighter Plane' and played the mouth organ part on 'Transparent Radiation'.

The lyrics were written by drummer Frederick Barthelme.

The cover version of "Transparent Radiation" was written and recorded based on the March 1967 demo version of the song on the International Artists Epitaph for a Legend compilation album released in 1980 rather than the original LP version on The Parable of Arable Land. Peter Kember would call songwriter Mayo Thompson who at the time was working for Rough Trade for a transcription of the original lyrics. Kember stated:

I told him I wanted to check the lyrics to "Transparent Radiation" because we were covering it and he didn't remember the song. [...] Over 10 years later, I met him in Los Angeles and he said that he loved my version. He liked the way we'd taken it from four chords to three chords. At the time we didn't really know.
