Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A ...

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 ...

This video excerpt explores the theorization of the Weak Force as it relates to the understanding of radioactive decay, with ...

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 ...

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, ...

The amount of long-lived radioactive elements incorporated into a rocky planet as it forms may be a crucial factor in determining its future habitability. That's because internal heating from the ...

Scientists poke and prod at the fringes of habitability in pursuit of life’s limits. To that end, they have tunneled kilometers below Earth’s surface, drilling outward from the bottom of mine shafts ...

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 ...

A new study identifies internal heating from radioactive decay as a critical factor in a planet’s ability to generate a magnetic field and retain an atmosphere. Credit: Illustration by Melissa Weiss ...
