       What is a Dirty Bomb?
 An Explosive designed to spread
  Radioactive material
 Also known as Radiological Dispersal
  Device (RDD)
 Combines a conventional explosive
  with radioactive material
 Example: Dynamite



                                         2
            Dirty Bomb
 Usually Built if unable to create a
  Nuclear Bomb
 Cruder and Cheaper than a Nuclear
  Bomb
 Doesn’t have same explosive
  damage.



                                        3
       Dirty Bomb Materials
 Many  types of Radioactive material
  could be used.
 Plutonium

 Uranium

 Nuclear Fuel

 Strontium 90

 Cesium 137



                                        4
         Other Materials
 AlsoMedical Supplies
 Radium

 Only takes a Measuring Cup’s Worth

 Wouldn’t cause severe damage in a
  wide area

Impact of a Dirty Bomb




                         6
Impact of a Dirty Bomb (cont’d)
 Nothing  like a nuclear weapon
 “Weapon of Mass Disruption”…not
  “Destruction”
 Act of explosion has a more instant
  effect than the radioactive material
 Most do not have enough radioactive
  material to kill or cause severe
  illness

                                         7
            Impact (cont’d)
 Certain  radioactive materials could
  contaminate several city blocks
 Requires a costly cleanup

 Installs fear and panic (!!!!!)




                                         8
         Factors of impact
 Sizeof the explosive
 Amount of radioactive material

 Type of radioactive material

 Material used

 Condition of the weather




                                   9
   Sources of Rad. material
Radioactive materials are used in:
              Hospitals

         Research facilities

   Industrial & construction sites




                                  10
      Controlling the source
 Controlmeasures have been
 tightened since 9/11




                               11
          Risks of Exposure
 Risks  of receiving cancer is small
 Exposure to the radioactive source is
  for a short period of time




                                      12
    What to do afterwards….
 GET  AWAY FROM THE AREA!!!
 Get inside
 Remove clothing…for testing
  purposes
 Take a shower (dust n’ dirt
  containing rad. material)

(all of these steps will reduce rad.
  Exposure)
                                       13
History of Use




                 14
          History (cont’d)
 1995:rebels from Chechnya
 planted…but did not detonate a dirty
 bomb; took place in Moscow

 Man  in London pleaded guilty with
 the intent to kill innocent people by
 the means of a Dirty Bomb
  (target: underground car parks)
