Nuclear Radiation

Figure from experiment 25 from Investigating Chemistry through Inquiry

Introduction

Nuclear radiation can be broadly classified into three categories. These three categories are labeled with the first three letters of the Greek alphabet: α (alpha), β (beta) and γ (gamma). Alpha radiation consists of a stream of fast-moving helium nuclei (two protons and two neutrons). As such, an alpha particle is relatively heavy and carries two positive electrical charges. Beta radiation consists of fast-moving electrons or positrons (an antimatter electron). A beta particle is much lighter than an alpha particle, and carries one unit of charge. Gamma radiation consists of photons, which are massless and carry no charge. X-rays are also photons, but carry less energy than gammas.

After being emitted from a decaying nucleus, the alpha, beta or gamma radiation may pass through matter, or it may be absorbed by the matter.

Objectives

In this Preliminary Activity, you will use a radiation monitor to determine the absorption of beta radiation by paper and by aluminum.

After completing the Preliminary Activity, you will first use reference sources to find out more about nuclear radiation before you choose and investigate a researchable question.

Additional Requirements

You may also need an interface and software for data collection. What do I need for data collection?
