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 ...

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 ...

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.
