Metreons are a type of particle.

In 2371, after scanning an energy barrier surrounding a Class L planet the USS Olympia was struck by a surge of metreon radiation. This radiation disabled the ship's engines and resulted in the death of all the crew in main engineering. With no engines the ship fell into the planet's atmosphere and crashed. (DS9: "The Sound of Her Voice")
