Extreme radiation can be avoided by the extremophilebacteria.

There is a science photo library.

It may be possible to live under the surface of Mars for a long time. If Mars ever hosted life, dried-upbacteria could stay alive for up to 280 million years, which would improve our chances of finding evidence for them.

The longest-lived hydratedbacteria were thought to be able to live for up to a million years. After desiccating a variety ofbacteria and yeast, Brian and his colleagues froze them and then exposed them to radiation similar to what a buried life form on Mars would experience.

When you get rid of the water, there is a huge increase in resistance. It is similar to freeze-drying to prolong its life.
