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 ...

Some nuclei of certain elements decay radioactively into nuclei of different elements. These decays can be useful or annoying depending on the context. This is especially true for potassium-40. This ...

Radioactive decay is a fundamental process in nature by which an unstable atomic nucleus loses energy by radiation. Studying nuclear decay modes is crucial for understanding properties of atomic ...

Scientists have observed a brand-new and exotic atomic nucleus: aluminium-20. Unlike anything seen before, it decays through a stunning three-proton emission sequence, shedding light on nuclear ...

Researchers at the National Institute of Standards and Technology (NIST) have unveiled a groundbreaking method for rapidly detecting and measuring radioactivity in minuscule samples. The technique, ...

In a random moment, all energy is lost. The unstable subject cannot help but decay, slowly but surely, letting go of particles to become stable. It loses itself to become balanced again. This is a ...
