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 half a century, our view of the world has been based on the standard model of particle physics. However, this view has been challenged by theories 1 that can overcome some of the limitations of ...

Segment 7A: Radioactive Decay We explore the nature of radioactivity. Segment 7A: Radioactive Decay We explore the nature of radioactivity and describes the types of radioactive decay that occur.

For the first time, a research team from the University of Cologne has observed the electron capture decay of technetium-98, an isotope of the chemical element technetium (Tc). Electron capture decay ...

Planning and Carrying Out Investigations: Designing experiments to measure radioactive decay and the effects of radiation. (Example: Conducting experiments to observe how distance and shielding ...

For the first time, researchers have directly observed an exotic type of radioactive decay called two-neutrino double electron capture. The decay, seen in xenon-124 atoms, happens so sparingly that it ...

A team of Italian researchers has uncovered compelling evidence of anomalous radioactive decay in cobalt-57 (Co-57) under ultrasonic stimulation, offering strong experimental support for the Deformed ...

Anomalies in the radioactive decay of beryllium-8 and helium-4 point to the existence of a new force of nature. That is the conclusion of a group of theorists in the US, who have scrutinized data from ...

The element radium can be found in extremely tiny amounts in the Earth’s crust and oceans, and in its pure form it is a soft silvery metal. To an untrained eye, a small piece of radium may look like a ...

Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to [email protected]. “What is radium and why is it dangerous?” – ...
