What Are Radioactive Materials?

Some are beneficial, while others may cause us harm. In this lesson you'll learn what radioactive materials are and explore where they come from and how. In this lesson, we'll go over the definition of radioactive elements. We'll learn about the different types of particles emitted during the process of radiation and look at some examples. Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s by Willard Libby, who received the Nobel Prize in Chemistry for his work in 1960.
