You may own a few radioactive gadgets without knowing it. We're talking about actual radioactive material here, not radiation ...

GE HealthCare agreed to acquire SOFIE Biosciences for $945 million, targeting SOFIE's 21-cyclotron US manufacturing network. The deal's logic lies in nuclear physics: fluorine-18 PET tracers decay in ...

For the first time, Northwestern University physicists have coaxed a single positron—the antimatter counterpart of an ...

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 ...

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 ...

How to measure the activity of radioactive sources. Atoms close atomAll elements are made of atoms. An atom consists of a nucleus containing protons and neutrons, surrounded by electrons. are very ...

Scientists did not arrive at Earth’s age from one clue. Several very different measurements keep pointing toward the same ...

Observing the recoil caused by a single radioactive decay could help physicists spot exotic particles and possibly even dark matter. Radioactive decay is ubiquitous. It occurs everywhere on Earth and ...

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 ...
