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 ...

Okay so I understand at a very basic level how radiometric dating works, but I have a question. How do scientists know the half-life of isotopes, when some of them are measured in millions or billions ...

In May 2016, close to the northern border of Switzerland, radiochemist Zeynep Talip suited up for the hot laboratory (Hotlab) at the Paul Scherrer Institute (PSI), where experiments with radioactive ...

Scientists have measured the half-lives of five never-before-seen isotopes in a first demonstration of a research facility that will help probe the nuclear structures of elements (Phys. Rev. Lett.

An international team of researchers has systematically measured the β-decay half-lives of 40 nuclei near calcium-54, providing key experimental data for understanding the structure of extremely ...
