All types of radioactive decay can be detected by a Geiger-Muller tube, or G-M tube. The radiations ionise the gas inside the G-M tube and the resulting charged particles move across the chamber ...

As this breakdown occurs, the activity of any radioactive source becomes less. This activity is measured in becquerels. Different radioactive ... The graph shows the decay curve for a radioactive ...

Many chemical elements in rock exist in a number of slightly different forms, known as isotopes. Certain isotopes are unstable and undergo a process of radioactive decay, slowly and steadily ...

and sugar cubes to simulate the radioactive decay of different isotopes. A radioactive isotope's nucleus is unstable and spontaneously decays, giving off radiation and changing into a different ...
