Space Elevator: Deadly Radiation?

Posted by Michael Pinto on Nov 15, 2006 in Science |

This article isn’t all doom and gloom as the headline might suggest, in fact what’s neat is that it has several suggestions to solve the radiation issue:

Space elevators: ‘First floor, deadly radiation!’

“Space elevators are touted as a novel and cheap way to get cargo, and possibly people, into space one day. So far, they have barely left the drawing board, but ultimately robots could climb a cable stretching 100,000 kilometres from Earth’s surface into space.

But there is a hitch: humans might not survive thanks to the whopping dose of ionising radiation they would receive travelling through the core of the Van Allen radiation belts around Earth. These are two concentric rings of charged particles trapped by Earth’s magnetic fields. “They would die on the way through the radiation belts if they were unshielded,” says Anders Jorgensen, author of a new study on the subject and a technical staff member at Los Alamos National Laboratory, New Mexico, US.”
