From cosmic rays to CT scans, radiation surrounds us but not all exposure is dangerous. Here’s how to separate fact from fear.

The discovery could explain why younger stars seem to have more lithium than the Big Bang theory says they should have.

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

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 ...

Using Nuclear Science in Food Irradiation Food Irradiation involves shining electromagnetic radiation like X rays and gamma rays or electron beams onto food to maintain food quality, kill harmful ...

NASA’s Fermi Gamma-ray Space Telescope "detected none of the high-energy gamma-ray light" from a nearby supernova. NASA explains. Credit: NASA Goddard Space Flight Center ...

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 ...
