People have apparently argued for a 300 to 30,000 years storage limit due to free radicals due to cosmic rays, but the uncertainty is pretty big. Cosmic rays and background radiation are likely not as much a problem as carbon-14 and potassium-40 atoms anyway, not to mention the freezing damage. http://ââwww.cryonics.org/ââ1chapter2.html has a bit of discussion of this. The quick way of estimating the damage is to assume it is time compressed, so that the accumulated yearly dose is given as an acute dose.
