GCSE Physics - Radioactive Decay and Half Life #35

The video tutorial explains radioactive decay, focusing on concepts like activity and half-life. It describes how activity is measured in becquerels and how half-life is defined as the time taken for radioactive nuclei or activity to halve. The tutorial uses graphs to illustrate decay processes and demonstrates how to calculate half-life. It also covers practical measurement of activity using a Geiger-Müller tube and provides an example problem to calculate remaining nuclei after several half-lives.
