When a nuclear bomb explodes far underground, the intense heat quite literally melts the surrounding rock into glass. In theory at least, scientists say this glass tomb will contain the blast's massive levels of radiation for the 100,000 years or longer it takes for the radiation levels to become safe. UAF researcher David Barnes says radiation is likely to eventually begin making its way through the island.
