Of the sources of the radioactivity that batters man, fallout from nuclear weapons testing is the least. At current levels, it is less than 5% of radiation from natural sources. But this is small ...

Background radiation is the invisible radiation that is always present in our environment. It comes from a variety of sources, both natural and man-made. Natural sources include cosmic rays from space ...

When we hear the word “radiation,” a certain image tends to pop up: toxic green barrels, blinking hazard signs, post-apocalyptic sci-fi vibes. But radiation didn’t arrive with nuclear power plants or ...

Researchers have developed a human in vitro model that closely mimics the complexities of radiation-induced lung injury (RILI) and radiation dose sensitivity of the human lung. Using a previously ...

A new detector system based on the game 'Tetris' could enable inexpensive, accurate radiation detectors for monitoring nuclear sites. The spread of radioactive isotopes from the Fukushima Daiichi ...

A study by scientists at Penn State and NASA shows that intact biomolecules from dormant microbes break down much more slowly ...

Jason Rivas is researching materials at the atomic level to improve reliability and resistance of electronics to space radiation. A PhD student in materials science and engineering at the University ...

The high-energy radiation that carries orbit angular momentum has become an extremely important tool to investigate the angular momentum-related physics in the microworld. But the generation and ...
