Cards (10)

  • Irradiation
    Irradiation is the process by which objects are exposed to radiation
  • Ionising radiation
    Radiation that has enough energy to remove an electron from an atom causing it to become positively charged
  • 4 types of ionising radiation
    Alpha radiation
    Beta radiation
    Gamma radiation
    X-rays
  • Contamination
    When radioactive particles get onto your body or other objects
  • What factors determine how harmful the radiation is
    The type of radiation
    Where you exposed the radiation
    The amount of radiation you receive
  • Why is alpha radiation the most harmful to the body
    Most ionising so damaged our cells the most
  • Why is ionising radiation harmful
    Damages our cells or cause mutation that can lead to cancer
  • For a radioactive substance 1m away from our body which type of radiation is most harmful
    Beta radiation as it would be able to reach our body and is moderately ionising
  • Which factors the amount of radiation you receive
    How far away from the source you are
    How long you’re exposed for
    How radioactive the substance is
  • What safety precautions can be taken when handling radioactive substances
    Use tongs when picking up radioactive substances
    Store the radioactive substances in lead-lined boxes
    Wear overalls/goggles/gloves
    Keep substance out for as short a time as possible
