Introduction

We've been talking a lot about nuclear chemistry in this unit. Remember in the beginning we discussed different types of nuclear radiation. Radiation is simply energy that is being emitted by something in the form of waves or particles.

Do you remember the three types of nuclear radiation we discussed? Check Answer

Well, radiation is actually a part of your everyday life. In fact you have probably been exposed to numerous forms of radiation already today. Now, don't get worried about this exposure – the levels you are being exposed to will not cause harm but it is good to be aware of them.

We come in contact with naturally occurring radiation in soils, rocks, and also from things made by humans. Your goal this lesson is to learn about some of the natural sources of radiation (not for example – nuclear power plants) that are around us on an everyday basis. At the end of the lesson, you will be creating a booklet to help make others aware of naturally occurring sources of radiation.

 

Lesson Objectives

Following successful completion of this lesson, students will be able to... Recognize examples of naturally occurring radiation Research and communicate information about naturally occurring radiation Enduring Understandings Chemical reactions occur constantly all around us. Nuclear reactions occur when changes happen in the nucleus of an atom. Nuclear reactions and nuclear power are important in everyday uses but can also pose many risks to people. The above objectives correspond with the Alabama Course of Study: Physical Science standards: 6a.
