The Two Types of RF Energy and Your Health
Hello, students!
This week we are talking about cell phone safety. We are learning about ionizing radiation and non-ionizing radiation. This video also explains a bit about it.
Let's watch this short video that explains how ionizing radiation can harm the body.
This is the kind of radiation that comes from x-rays, nuclear medicine, the sun's rays, and cosmic background radiation. It is NOT the kind of radio frequency energy emitted by cell phones.
We looked at that in class. Before reading the text, we explored the new vocabulary. Each pair of students was responsible for teaching two words.
