1. Gamma Rays
By Miles, Raj, and Tony

2. Statistics Wavelength is between 10 and 1 pm (picometers)
Frequency is between 30 and 300 EHz
Most energetic wave on the electromagnetic spectrum

3. Discovery Paul Villard 1900
French physicist who worked in Paris at the same time as Marie Curie
Used lead to stop Alpha and Beta rays, the other ray that penetrated was called Gamma

4. Uses Used to treat Cancer Used in CT Scans

5. Danger Gamma Rays kill cells in living organisms
Overexposure can cause nausea, hair loss, hemorrhaging and eventually death

6. Visibility
Humans and other organisms can’t see it because it is such a high frequency
This is because Gamma Rays are 10,000,000,000 more energetic than visible light waves
