Resources for your classroom
Career Information [toc]
Learn about careers in radiation safety—protecting people and the environment from the harmful effects of radiation while helping all of us benefit from the useful application of radiation science.
Radiation Science Instrumentation and Radiation Sources [toc]
- HPS Radiation Instrument Kit is a collection of equipment and materials for basic radiation science demonstrations and laboratory exercises that is loaned to teachers. This form must be opened up in Adobe Reader in order to fill in the form using your keyboard.
- Vernier Software & Technology. This company produces simple-to-use and inexpensive computer-based equipment for basic nuclear science experimentation. A laboratory manual is available providing teachers with ready-to-use instructions.
- Spectrum Techniques provides inexpensive radiation sources for use in the classroom. Refer to the listing for exempt sources.
- Oak Ridge Associated Universities provides a listing of the operating and maintenance manuals for a wide variety of civil defense radiation survey meters.
- Instructions for modifying a surplus civil-defense Geiger-Mueller counter allows the analog survey meter to be converted to a digital counter with audio output.
Safety of Radiation Sources in the Classroom [toc]
This document provides guidance on using radiation sources safely in elementary and secondary classrooms.
Demonstrations and Classroom Activities [toc]
- Irradiated salt demonstration. Did you receive a sample of gamma-irradiated salt from a member of the Health Physics Society? Read the full instructions for using the salt to demonstrate thermoluminescence.
- Calculate your annual radiation exposure activity. Use this calculator from the U.S. Environmental Protection Agency to estimate the amount of radiation you're exposed to during a year.
- Calculate your annual radiation exposure activity. Use this calculator from the American Nuclear Society to estimate the amount of radiation you're exposed to during a year.
- Radioactive decay simulation using candy. This radioactive decay activity from the American Association for the Advancement of Science uses candy as a surrogate for radioactive material.
- Radioactive decay simulation using coins. This activity leads students through an activity using pennies to explore the concept of radioactive decay.
- Half-Life: A Classroom Exercise. This activity includes a lot of background about the theory of radioactive decay and was developed by a university professor and radiation safety professional.
Lesson Plans and Other Curriculum Materials [toc]
This section includes a series of lesson plans and other classroom materials developed by U.S. government agencies, nuclear science organizations, university professors, and other professionals.
Lesson Plans Created by the Health Physics Society [toc]
- Elementary Class Introduction to Radiation contains suggestions for introducing the concepts of ionizing radiation to elementary class students using visible light as an analog. Useful talking points and demonstrations in the form of a script are provided.
- Introduction to Radiation and Radiation Detection: Background Radiation is a detailed exploration of using a radiation detector to identify naturally radioactive materials. Comprehensive notes for the teacher are included so that suitable radiation-emitting samples can be obtained.
- Investigating Properties of Radiation is a simple inquiry-guided experiment that helps students determine what materials can be used to absorb different types of radiation. The experiment requires different types of radiation sources, different types of shielding materials, and a radiation detector sensitive to alpha, beta, and gamma radiation.

Contact the HPS Science Support Committee [toc]
The Health Physics Society offers two awards annually: The Geoffrey G. Eichholz Outstanding Science Teacher Award and the Student Science Award. The Science Teacher Awards allows us to honor teachers (K-12) that have made significant contributions to educating students in topics related to radiation safety. The Student Science Awards recognizes the contributions of those students in grades 6-12 to the understanding of the application of radiation and its impact on the environment and health. Both awards have monetary compensation. As teachers and educators you are in the best position to help us identify individuals deserving of these awards. Contact either the chair of the Science Support Committee or the chair of the HPS Awards Committee for additional details.
If the resources provided here haven't answered your questions, or if you would like to talk to a local radiation safety professional about visiting your classroom, please contact us and we'll try to address your needs.
