In this section we look inside the atom and the subatomic world. This is where things start to get really strange!
Choose your topic:
Atomic Models [FREE] - Plum puddings to the Rutherford-Bohr model
Atoms [FREE] - Never trust an atom - they make up everything!
Nuclear Radiation - Unstable isotopes emit particles from their nucleus
Nuclear Equations - These show what happens when alpha, beta and gamma are emitted
Background Radiation - You can't escape it, you are currently being irradiated
Hazards of Radiation - There are a few dangers....
Half-life - The time it takes for the number of nuclei in a sample to halve
Uses of Radiation - Radioactive sources are incredibly useful for many applications
Medical Uses of Radioactivity - Radioactivity, although hazardous, has many benefits
Fission and Fusion - Releasing energy from splitting, or joining, nuclei
