How Does Radiation Affect You?
Students identify the use and misuse of radiation. They examine human activities that add to the exposure of radiation. They also discover how it can be useful in saving lives.
Curated OER
How Much Radiation is Around You?
Learners examine the use, misuse and fear of radiation. They read an article about radiation on food and discuss the positives and negatives of this process. They answer questions to complete the activity.
