How NASA prepares spacecraft for the harsh radiation of space
(PHYSorg.com Space & Earth)

In a small, square room walled by four feet of concrete, the air smells as if a lightning storm just passed through-crisp and acrid, like cleaning supplies. Outside, that`s the smell of lightning ripping apart oxygen in the air, which readily reshuffles into ozone. But belowground in one of the rooms at NASA`s Radiation Effects Facility, the smell of ozone lingers after high-energy radiation tests. The radiation that engineers use to test electronics for spaceflight is so powerful it shreds the oxygen in the room.
