Space radiation is quite different and more dangerous than radiation on Earth

Scientists can predict with confidence what the effect of the Japanese disaster has had and will continue to have thanks to a legacy of data on radioactive pollution in the environment after decades of nuclear testing worldwide

Researchers at the Wake Forest Institute for Regenerative Medicine and colleagues are using human stem cells to measure the effects of deep space radiation

Currently there is no cure for exposure to lethal doses of radiation

If the technique can be scaled up and proven under real inspection conditions, it could significantly improve the ability to prevent the smuggling of dangerous nuclear materials

American Chemical Society examines the basics of survival in a world riddled with radiation.

Researchers report the site looks more like a nature preserve than a disaster zone

Scientists have discovered an invisible shield roughly 7,200 miles above Earth that blocks so-called “killer electrons,” which can fry satellites and degrade space systems during intense solar storms.
