Not all of the material around us is stable. Some materials may undergo radioactive decay to form more stable isotopes. Scientists have now observed a new decay mode for the first time. In this decay, ...

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 ...

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 ...

For the first time, scientists observe a new and rare decay mode where oxygen-13 breaks into three helium nuclei and a proton following beta decay. Scientists have previously observed interesting ...
