Cloudy with a chance of radiation: NASA studies simulated radiation
(PHYSorg.com Space & Earth)

In each life a little rain must fall, but in space, one of the biggest risks to astronauts` health is radiation `rain`. NASA`s Human Research Program (HRP) is simulating space radiation on Earth following upgrades to the NASA Space Radiation Laboratory (NSRL) at the U.S. Department of Energy`s Brookhaven National Laboratory. These upgrades help researchers on Earth learn more about the effects of ionizing space radiation to help keep astronauts safe on a journey to Mars.
