One of the first things that Physics students learn when they study radioactivity is the idea of the half-life. A half-life is the period of time in which it takes one-half of a given amount of a ...

In this video excerpt from NOVA's "Hunting the Elements," New York Times technology columnist David Pogue explores how isotopes of carbon can be used to determine the age of once-living matter. Learn ...

Radioactive material gets a bad rap, what with radiation and fallout and nuclear waste and all. But it offers some practical uses. One of the coolest (OK, maybe the coolest) is using radioactive ...

Radioactivity, discovered more than 100 years ago and studied by physicists ever since, would seem to be a relatively closed subject in science. However, since the 1960s, the pursuit of at least one ...

Solar activity: does the Sun affect radioactive decay? Image of a solar flare taken in 2014 by NASA's Solar Dynamics Observatory spacecraft. (Courtesy: NASA/SDO) A new study of the radioactive decay ...

Radioactive decay is a fundamental process in nature by which an unstable atomic nucleus loses energy by radiation. Studying nuclear decay modes is crucial for understanding properties of atomic ...
