The Fukushima Daiichi nuclear disaster spread significant radioactive contamination over more than 3500 square miles of the Japanese mainland in the spring of 2011. Now several recently published studies of Chernobyl, directed by Timothy Mousseau of the University of South Carolina and Anders Møller of the Université Paris-Sud, are bringing a new focus on just how extensive the long-term effects on Japanese wildlife might be.
Scientists have discovered a massive particle accelerator in the heart of one of the harshest regions of near-Earth space, a region of super-energetic, charged particles surrounding the globe called the Van Allen radiation belts.
All the objects around us emit thermal radiation. Usually, this radiation can be described very accurately using Planck’s law. If, however, the radiating object is smaller than the thermal wavelength, it behaves according to different rules and cannot emit the energy efficiently.
The Earth temporarily gained a third radiation belt last year, NASA's Van Allen Probes mission has revealed.
Astronomers are baffled by the discovery of a pulsar - a tiny spinning stars, heavier than the sun and smaller than a city - that emits different types of radiation at different times.
Astronauts venturing beyond the safety of the International Space Station (ISS) will face increased exposure to cosmic radiation.
NASA's finally launched its Radiation Belt Storm Probes (RBSP), the first twin-spacecraft mission designed to explore the Van Allen belts.
Radiation causes ten times as much structural damage to electronic materials at the atomic level as previously believed, say scientists using a new investigation technique.
Scientists from the UK's Rutherford Appleton Laboratory have made a discovery that could help future astronauts shelter from radiation on the moon.
With a solar storm washing over the Earth this weekend, it's welcome timing for a new solar radiation warning system that gives more warning than ever before.
If there's any evidence of ancient life on Mars, it's likely to be found near the surface, new research suggests - dramatically upping the chances that it'll be discovered by the Curiosity rover, set to land next month.
Researchers at the Georgia Tech Research Institute (GTRI) have created a new prototype radiation detection device for use at ports, border crossings, airports and elsewhere.
Radiation from nuclear disasters such as Chernobyl and Fukushima may, surprisingly, have done the local wildlife no harm at all.
Berkeley Lab scientists are soon to move into clinical trials of a pill that can decontaminate people after exposure to radiation.
Factory Fifteen has released a short, yet haunting sci-fi film dubbed GAMMA. The surreal movie depicts a post-nuclear future, in which the earth is riddled with dangerous radiation.
A federal judge has thrown out most provisions of a San Francisco law requiring phone retailers to display the amount of radiation emitted by each device.
A new study from the Environmental Health Trust has found that children absorb twice as much microwave radiation from phones as do adults.
Russian city Chelyabinsk - widely known as the most polluted in the country - is using taxpayers' money for a search engine optimisation project aimed at cleaning up its image (though not the city itself).
Tawkon has been making quiet ripples in the smartphone market. But most people only heard of the Israeli firm after the dramatic rejection of its app by the chief Apple guru himself - Steve Jobs.
While US personnel in Japan have been issued with supplies of potassium iodide in the event that they need treatment for radiation sickness, it's very much a last-ditch solution.
