Using Nuclear Science in Food Irradiation

This issue of ReActions provides a variety of resources for your students to explore the many ways that radiation and nuclear technology are used to improve crop and livestock production and improve the freshness and safety of our food. This video from the International Atomic Energy Agency provides a quick introduction to the topic.

Did you know that irradiation does not make food radioactive, and irradiated foods look and taste just like other fresh, raw food? Radiation technology is used in a wide variety of ways to improve our quality of life, including the food we eat. In fact, radiation processes not only improve food production and ensure ready access to more healthful food that stays fresher longer, they also care for the environment!  Click here for more information about how nuclear science is used in agriculture.

What happens to seeds that are exposed to very high levels of radiation? Will they grow normally?  Students will learn by observing in this activity aligned with DCI and NGSS. They will develop a procedure to study the effects of radiation on mung bean seeds and other irradiated seeds, and observe and record data on the germination and development of the plants. Their data, results, and conclusions will be presented, supported, and defended to the class. Click here for the lesson plan.
