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 ...
Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to [email protected]. “What is radium and why is it dangerous?” – ...
Think about a garden where flowers bloom beside nuclear reactors. It sounds impossible, yet it's happening right now. Since ...
Half of the extraordinary heat of the Earth that erupts on its surface volcanically and drives the titanic motions of the continents is due to radioactivity, scientists find. This new discovery shows ...
In this lesson, students will investigate the nature of radioactivity and the effect of both distance and shielding materials on different radioactive sources using a Geiger-Muller tube with a counter ...
An international team of researchers has completed the most precise measurement of the Earth's radioactivity to date. By analyzing subatomic particles streaming out of the interior of the planet, the ...
Among the many science toys that have fallen out of fashion since we started getting nervous around things like mercury, ...
When cells are exposed to ionizing radiation, more destructive chain reactions may occur than previously thought. An international team led by researchers has now observed intermolecular Coulombic ...
Ghostly subatomic particles streaming from Earth’s interior have enabled the most precise measurement yet of our planet’s radioactivity. These particles, called antineutrinos, suggest that about half ...
The Standard Model of physics, which explains the properties and interactions of the fundamental particles, does a phenomenal job with the things it gets right, and there's nothing that it obviously ...
One of the ways we measure the age of the Earth is using the half-life of uranium. With a half-life of around four billion years, your typical atom of uranium only has even odds of having decayed ...
