  • Ionsing Radiation
    • Radioactive substances give out radiation all of the time.
    • There are three types of nuclear radiation
      • Alpha Particels
        • Alpha is the least penetrating
          • all three are ionising radiation: they can knock electrons out of atoms and form charged particles..
            • Beta Paricels
      • Beta Paricels
      • Gamma Rays
        • gamma is the most penetrating.
          • all three are ionising radiation: they can knock electrons out of atoms and form charged particles..
      • Radiation can be harmful, but it can also be useful - the uses of radiation include to:
        • detect smoke
        • gauge the thickness of paper
        • treat canser
        • sterilizer medical equipment.
      • Nuclear radiation
        • comes from the nuclus of an atom
        • Substances that give out radiation are said to be radioactive..
        • All radiation transfers energy
        • All types of radiation become less intense the further the distance from the radioactive material, as the particles or rays become more spread out..
          • The thicker the substance, the more radiation is absorbed.
