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 ...

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 ...

This activity is measured in becquerels. Different radioactive isotopes have different half-lives. For example, the half-life of carbon-14 is 5,730 years, but the half-life of francium-223 is just ...

JON CHASE:'Nuclear weapons, nuclear power stations 'and life-saving medical techniques, all use radioactivity. JON CHASE:'But what is it? 'Elements ... half-life of a naturally occurring ...

In 1902 Ernest Rutherford and Frederick Soddy discovered that radioactive elements, such as uranium ... rate at which uranium breaks down (its half-life), he could use the proportion of lead ...

Researchers at the University of Jyväskylä’s Accelerator Laboratory ... rich radioactive nuclei. The generated isotopes are difficult to examine because of their short half-life.

Early in the war Flerov had noticed that the flow of articles about radioactive ... a half-life of 51.5 days, researchers seemed to be getting close. IN THE ELEMENT KITCHEN - The Russian lab ...
