The moment nuclear material is produced, processed or purified, it sets off a hidden countdown, marked by the half-life of ...

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a new and faster method for detecting and measuring the radioactivity of minuscule amounts of radioactive ...

A team of Italian researchers has uncovered compelling evidence of anomalous radioactive decay in cobalt-57 (Co-57) under ultrasonic stimulation, offering strong experimental support for the Deformed ...

A battery made of diamonds could power devices for thousands of years, scientists have announced. This battery would be powered by a diamond surrounding a radioactive isotope of carbon known as carbon ...

Facilities that work with radioactive materials require practical solutions for small quantities of isotopes and radioactive waste.

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 ...

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 blast is what people imagine. A sudden flash, a rising cloud, the moment when history splits into “before” and “after”. Nuclear disasters and atomic weapons are often pictured as events that ...

Among the many science toys that have fallen out of fashion since we started getting nervous around things like mercury, chlorinated hydrocarbons, and radiation is the spinthariscope, which let people ...

The element radium can be found in extremely tiny amounts in the Earth’s crust and oceans, and in its pure form it is a soft silvery metal. To an untrained eye, a small piece of radium may look like a ...
