​

•  Half-life - The time it takes for the number of nuclei in a sample to halve

​

• Hazards of Radiation - There are a few dangers....

​

•  Uses of Radiation  - Radioactive sources are incredibly useful for many applications

​

•  Background Radiation  - You can't escape it, you are currently being irradiated

​

•  Medical Uses of Radioactivity  - Radioactivity, although hazardous, has many benefits

​

•  PET Scanners  - Positron Emission Tomography

​

•  Fission and Fusion  - Releasing energy from splitting, or joining, nuclei
