Depleted uranium munitions are bad news for enemy tanks, but are not nuclear weapons, and studies have shown that they pose low risks of radiation or chemical exposure.

Radiation from the brightest cosmic explosion ever seen may have been mixing with gas and dust around its dying star – making the signal last longer.

The International Atomic Energy Agency says the plant has enough water to last for several months. What happens afterward or if the remaining water is lost to the war could lead to a disaster.

Studying the brief and tiny quantum effects that drive living systems could one day lead to new approaches to treatments and technologies.

Zoning out to a favorite video during radiation treatments can help kids with cancer hold still and skip anesthesia, a new study shows.

A new study has found that dust launched from the moon’s surface or from a space station positioned between Earth and the sun could reduce enough solar radiation to mitigate the impacts of climate change.

A new effort significantly reduces the number of unnecessary CT scans in children, limiting exposure to harmful radiation.

A technique that tracks radiation in real time promises safer, more effective cancer therapy with less collateral damage, researchers say.

A new approach that combines a gel-like radiation implant and chemotherapy completely dissolved pancreatic cancer in 80% percent of mice.
