A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay (𝛼-decay), beta decay (𝛽-decay), and gamma decay (𝛾-decay), all of which ...

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 ...

There are three main types - alpha, beta or gamma ... Pupils could explore decay chains and complete equations to show radioactive decay processes. They could also plot graphs of given data ...

Students can understand the mechanism of radioactive half-life and how it helps determine age by experimenting with pennies, dice, and sugar cubes to simulate the radioactive decay of different ...

Certain isotopes are unstable and undergo a process of radioactive decay, slowly and steadily transforming, molecule by molecule, into a different isotope. This rate of decay is constant for a ...

There are three general approaches that allow scientists ... Some commonly used dating methods are summarized in Table 1. The rate of decay for many radioactive isotopes has been measured and ...

Powering spacecraft with solar energy may not seem like a challenge, given how intense the Sun’s light can feel on Earth.

Of the four known fundamental forces of nature, the weak nuclear force is the one ... Protons and neutrons are both composites of three quarks of two types, or “flavours”, up and down.
