Dangers of Radiation

• Define irradiation and contamination.

  Irradiation is the process of exposing an object to radiation.

  Contamination is when radioactive material is deposited on or in an object or a person
• Give two example of how to protect against contamination and irritation:

  • Keeping the time of exposure to a minimum, - Contamination
  • Maintaining distance from the source, - Contamination
  • Create barriers of lead, concrete, or water
  • keep distance
• Compare the hazards of how to protect against:

  a.) contamination, b.) irradiation.

  alpha is less dangerous because it can’t penetrate the skin but inside the body alpha is the most dangerous because they do damage in very localised areas
