Students investigate the concept of half-life by conducting an M&M experiment. In this chemistry lesson, students differentiate nuclear fusion and fission. They present investigation findings to class.

In this nuclear chemistry worksheet, students are given the biological effects of nuclear radiation. They are also given a list of uses of nuclear chemistry and Einstein's theory of special relativity to calculate the energy change in...

In this biology worksheet, students review the procedures used to complete the lab activity and then examine the purpose and add the information while answering the questions.

In this quantities in chemistry worksheet, students solve 13 review problems about percent composition, significant digits, the mole, simple and molecular formulas, balancing equations, stoichiometry, limiting reagents and percent yields.

In this radioactivity quiz worksheet, students complete a 10 question true/false quiz. Quiz is also available as a student handout and Powerpoint presentation. 

Students will discuss the de Brogile Hypothesis and state the circumstances under which the wave nature of matter is observed. They will also calculate the wavelengths of matter waves.

Young scholars evaluate the ways to control exposure to radiation and determine how to deal with the problem of nuclear waste in a rational rather than an emotional way.

In this radioactivity worksheet, learners write the mass number and atomic number for the missing element in the reactions. Students identify the isotope that is more stable and determine the half-life of the isotope. This worksheet has...

Students read an article about radon and its properties. They examine a periodic table and identify the numbers surrounding an element. They discuss the harmful and helpful effects of radiation.

Learners examine what radon is and which isotope it belongs. They discuss the characteristics of isotopes in general and the atomic number. They complete a worksheet to complete the lesson.

Students examine the effects of radon on the lungs. They review pictures of the lungs on a large and small scale. They work together to answer questions to complete the lesson.

Pupils identify the different sources of radiation around us. In this physics lesson, students calculate their estimated radiation exposure per year. They research a current issue about radiation.

Watch alpha particles escape from a polonium nucleus, causing radioactive alpha decay. See how random decay times relate to the half life. Java required.

[Free Registration/Login may be required to access all resource tools.] How and why alpha decay occurs, its dangers and how to write a balanced nuclear equation for alpha decay.

Via this interactive SIMS experiment, students will grasp better understanding of decay in alpha particles and their relationship to half life. Lessons and teacher tips included.

Using examples, this page defines and explains what happens in the process of alpha decay.

This article from Khan Academy provides information about radioactive decay. This information is intended for the Class 12 Physics Course (India).

Explains the processes of radioactive decay in primary and secondary modes.

This site from the Jefferson Lab provides a glossary item with a good illustration.

[Free Registration/Login may be required to access all resource tools.] Summarizes the key points about how radioactive particles decay. Includes a few questions to check for understanding.

A basic explanation of beta decay.

This article with embedded videos provides information about three main types of radioactive decay: alpha, beta, and gamma.

This interactive unit will take students up close and personal with the nuclei of atoms as they discover some of their more intimate process. These will include radioactive decay, nuclear fission, and nuclear fusion.

An interactive tutorial on positrons. Very readible and has a little extra for the advanced student.
