Scientists have gained insights into the weak nuclear force from new, more sensitive studies of the beta decays of the 'mirror' nuclei lithium-8 and boron-8. The weak nuclear force drives the process ...

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 ...

Hickory dickory dock, this nucleus could make a great clock. A special variety of the element thorium hosts an atomic nucleus that could be used to keep time, scientists say. In a first, researchers ...

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 ...

Nuclear power is considered one of the ways to reduce dependence on fossil fuels, but how to deal with nuclear waste products is a concern. Radioactive waste products can be turned into more stable ...

Radiation is energy that moves from one place to another in a form that can be described as waves or particles. We are exposed to radiation in our everyday life. Some of the most familiar sources of ...

The rise of a new generation of radiotherapies means we will soon need much greater quantities of radioactive atoms. That's ...
