Deinococcus radiodurans is a bacterium, an extremophile and one of the most radiation-resistant organisms known. It can survive cold, dehydration, vacuum, and acid, and therefore is known as a polyextremophile. The Guinness Book Of World Records listed it in January 1998[1] as the world's most radiation-resistant bacterium or lifeform.[2]

  1. ^ "Most radiation-resistant lifeform". Guinness World Records. Archived from the original on June 23, 2015. The red-coloured bacterium Deinococcus radiodurans can resist 1.5 million rads of gamma radiation, about 3,000 times the amount that would kill a human. The bacteria was first isolated from cans of meat that were subjected to supposedly sterilising doses of radiation in the megarad range.
