Life doesn’t always need sunlight. In fact, in some of the coldest, darkest places in the solar system, the spark for life might come from something far more extreme: cosmic rays. A new study led by ...

In physics terms, radiation is simply energy on the move, carried by waves like sunlight or particles like those released by radioactive decay. And since the universe is mostly energy, radiation is ...

Tampa Bay Rays have a favorable schedule after a front-loaded slate at their temporary home.

The radiological threat from the targets of the earliest attacks are relatively minor.

Thunderstorms are known to generate gamma rays, the highest energy radiation on Earth. But pinning the burst to a specific bolt is new.

For the first time, scientists have caught lightning in the act of unleashing a powerful burst of gamma radiation known as a terrestrial gamma-ray flash (TGF). Researchers at the University of ...

Since silver isotopes, like radioactive atoms of other elements, have their own characteristic half life—or rate of decay—and emit gamma rays at a specific energy level, the snooper’s ...

In addition to understanding the formation of heavy elements, the proposed framework helps address critical questions around neutron transport, multiphysics simulations, and the observation of ...

The radioactive 198 Au emits gamma rays, which are detectable from outside the body. “Activation of atoms through particle irradiation is a technique that directly alters the material,” Kataoka ...

These unstable isotopes undergo secondary radioactive decay to produce gamma rays or beta particles, which is known as secondary radiation. Therefore, Gd-containing composite shielding materials must ...

The radioactive 198 Au emits gamma rays, which are detectable from outside the body. Prof. Kataoka explains neutron activation, stating, “Activation of atoms through particle irradiation is a ...
