Chapter 8: Radioactivity
What you need to learn in this chapter
In this chapter, we will learn about the history of the discovery of radioactivity. We will explore the concept of radioactive materials and the phenomenon of radioactivity, as well as the concept of half-life. We will also study the structure of an atom and its nucleus, including the formation of positive and negative ions.
Furthermore, we will discuss the difference between ionising radiation and non-ionising radiation. We will learn about the three types of ionising radiation in radioactive decay. Additionally, we will examine the various uses of radioactive radiation for the well-being of society.
Lastly, we will understand the importance of proper handling of radioactive substances and radioactive waste. It is crucial to ensure safety and prevent any harmful effects.
