It’s a situation that was unthinkable before.” Gamma-ray radiation is an effective method for low-temperature sterilization, and is also effective against endotoxins, enabling sterilization ...

It's not easy to imagine how high the frequency of a high-energy gamma ray is. During the time it takes for its wave to go through one cycle, a gamma-ray wave traveling at the speed of light will ...

For over a decade, a star system on the verge of unleashing a deadly gamma ray burst appeared to have its guns trained on Earth. The so-called "Death Star," which is also famed for looking like a ...

PGAA is particularly valuable as a non-destructive nuclear method in the measurement of elements that do not form neutron capture products with delayed gamma-ray emissions. Inaccurate and incomplete ...

"This field did not exist before 1989 when the first gamma ray source was detected. At that point, we knew of four sources in the world," said Dave Kieda, professor in the Department of Physics ...

We could pull a Bruce Willis in Armageddon, maybe. It's a fair game. A nearby gamma-ray burst could kill us all. And they can move at close to the speed of light, so oblivion would strike very ...

It does this by emitting a high energy electromagnetic wave called a gamma ray. Gamma radiation does not consist of particles but as short wavelength, high energy electromagnetic radiation emitted ...
