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 ...

The process: The study focuses on a radiation-induced process by which weakly bound matter can fall apart, the so-called electron-transfer-mediated decay (ETMD). Given predictions that it efficiently ...

University of Tennessee, Knoxville physicists and their colleagues have made critical measurements of the lifetime and decay ...

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 ...

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 ...

Nuclear energy isn't as clean as we like to believe. The associated power plants produce small amounts of nuclear waste that require proper disposal. The main enemy here is time. All radioactive ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

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 ...
