An international team of researchers has systematically measured the β-decay half-lives of 40 nuclei near calcium-54, ...

What these two processes share is baked into the math of each. In fact, in that respect, they're nearly identical. They both involve some stuff (atoms or money) that is either growing or shrinking.

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 ...

Reader @Procrustes tweeted at us to ask: “Why do scientists measure things like radioactive elements in half-life? Why not just measure the whole life?” If you’re not familiar with the term “half-life ...

The discovery of radioactivity allowed scientists to develop new methods of determining Earth's age, with astonishing results. Our planet is far older than people had thought! Students can understand ...

April 24 (UPI) --The half-life of the isotope xenon-124 is a trillion times longer than the age of the universe. Observing such a slow decay would seem impossible, but scientists working on the XENON ...
