  • Effects  of  Radiation •  Nausea  •  Vomi/ng  •  Headache  •  Some  loss  of  white  blood  cells  •  Temporary  hair  loss  •  Loss  of  white  blood  cells  •  Reduces  produc/on  of  blood  platelets  •  Fever  •  Diarrhea  
  • Fallout •  Mother’s  child  exposed  to  radia/on  become   serious  disease.  •  Leukemia,  lung  cancer,  thyroid  cancer,  breast   cancer,  and  cancers  of  other  organs.  
  • Hiroshima  and  Nagasaki •  Many  people  died  not  directly  from  the   explosion.  •  They  died  from  the  radia/on  released  as  a  result   of  the  explosion.  
  • Three  Mile  Island •  Blocked  the  flow  of  water  in  the  main  feedwater  system  of  a   reactor.  •  Tore  the  reactor  apart.  •  Radioac/ve  water  flowed  into  an  auxiliary  building,  where  it   pooled  on  the  floor.  •  Radioac/ve  gas  was  released  into  the  atmosphere.  •  Cost  lots  of  money  and  /me,  no  one  was  hurt.
