The circle in the middle of the trefoil represents an atom and the blades represent the three common types of ionizing radiation emanating from it — alpha (α), beta (β) and gamma (γ). The symbol was ...

To reduce the strength of incoming gamma rays by a billion, you need 13.8 feet (4.2 meters) of water, 6.6 feet (2 m) of concrete or 1.3 feet (0.39 m) of lead, according to the radiation protection ...

Gamma rays are the most energetic form of electromagnetic radiation. In just a few seconds, a gamma-ray burst blasts out the same amount of energy that the Sun will radiate throughout its entire life.

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 ...

For context, one of those visible wavelengths carries an energy of about 1 electron volt. The gamma rays Nisa and fellow researchers witnessed, by contrast, exuded about 1 trillion electron volts.

A new study suggests that explosive events in space have the potential to temporarily switch off the natural shield that protects us from harmful solar radiation. By Katrina Miller On Oct. 9, 2022 ...
