- Absorbed Dose and Equivalent Dose
- Activity
- A=N/t
- Activity=
Number of
atoms/time
- Half-Life
- How long it takes for the
activity to decay by half
- Fission
- Where the atoms are broken apart to create
energy- e.g: A nuclear power plant uses fission by
firing neutrons to into atoms to break them apart
and create energy
- Fusion
- Where two smaller
atoms with hydrogen
in them are joined
together to make a
bigger atom

- Wavelength and amplitude
- T and F
- Wave Speed
- Speed, f, wavelength
