Astronauts face radiation threat on long Mars trip

May 31, 2013 3:26 pm | by ALICIA CHANG, AP Science Writer | News | Comments

Astronauts traveling to and from Mars would be bombarded with as much radiation as they'd get from a full-body CT scan about once a week for a year, researchers reported Thursday. That dose would, in some cases, exceed NASA's standards and is enough to raise an astronaut's cancer risk by 3 percent.
