Every second in your body, thousands of tiny isotopes are bursting with radioactive decay. And, all around you, imperceptible gamma rays explode in a brilliant but invisible lightshow. And they've ...

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 ...

Radioactive elements on Earth are like geological watches. A radioactive isotope of carbon is used to date human civilizations, among other things, because we know that its half-life is precisely ...

Discover the fascinating process of radioactive decay, where unstable atoms transform, releasing energy in the form of alpha, beta, and gamma emissions.

Russia’s state weather agency has reportedly said that it found radioactive isotopes in test samples after an accident at a military test site that killed five people earlier this month. A cloud of ...

In this lesson, students will simulate the randomness of decay in radioactive atoms and visualize the half-life of a sample radioactive element. This lesson can be completed in two (2) 45-minute class ...

The Sun is changing the supposedly constant rates of decay of radioactive elements, and we have absolutely no idea why. But an entirely unknown particle could be behind it. Plus, this discovery could ...

It's been seven years since a University of Hawaii telescope spotted a strange object crossing our solar system. One-quarter mile (400 meters) long and maybe ten times as long as it is wide, thus ...

Add Yahoo as a preferred source to see more of our stories on Google. The findings of a new study suggest radioactive decay rates — long considered physical constants — are more variable than ...

Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4.6 billion years. Mountains have been built and eroded, continents and oceans have moved ...
