International Space Station engineers Chris Cassidy and Tom Marshburn have plugged the ammonia coolant leak on the orbiting science lab. The pair's successful spacewalk and repair job over the weekend has cleared the way for their crewmates to set off home for Earth tonight. Flight Engineers Cassidy and Marshburn completed …

Thats interesting, I was under the impression that the radiation which causes long term damage became an issue just outside geostationary orbit.
The Earth's magnetosphere protects against a lot of it though.
These are hard to shield against i.e. high energy ion radiation which causes double strand DNA breaks likely to lead to permanent damage.
