P2 Radiation and Life
  1. Types of Radiation
    1. 1. Radiowaves- LOWEST frequency (non ionising)
      1. 2. Microwaves- mobile phones, shortest wavelength (non ionising)
        1. 3. Infra red- Toaster (non ionising)
          1. 4. Visible light- we can see it (non ionising)
            1. 5. UV- suns radiation can lead to skin cancer (ionising)
              1. 6. x-rays- HIgh frequency (ionising)
                1. Gamma rays- Used to treat/kill cancer cells, highest frequency (ionising)
                2. Ionisation- Happens when a photon with enough energy hits an atom/molecule inside a material
                  1. Elecromagnetic spectrum- different types of radiation
