Gamma rays (denoted as γ) are electromagnetic radiation of high energy. They are produced by sub-atomic particle interactions, such as electron-positron annihilation, neutral pion decay, radioactive ...

Trump stumps, putting affordability crisis blame where it belongs | Opinion A Russian drone hit a rescue robot evacuating a wounded Ukrainian soldier — the bot shielded him from further injury, ...

In this lesson, students will investigate the nature of radioactivity and the effect of both distance and shielding materials on different radioactive sources using a Geiger-Muller tube with a counter ...

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 ...

Particle and nuclear physics evokes evokes images of huge accelerators probing the extremes of matter. But in this round-up ...

Naturally occurring radioactive elements are substances whose atomic nuclei are unstable. To become stable, these nuclei spontaneously break down, or decay, by releasing energy in the form of ...

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 ...
