Death ! Very high levels of radiation exposure often lead to
death within a FEW DAYS or WEEKS
Cancer ! Estimated that about 0.4% of all cancers in the US are
attributed to radiation from CT Scan
DNA Damage ! Can bring about cell mutation, cell suicide, and
random cell division.
Internal Damage ! Possible Symptoms of radiation exposure include
inflammation of the sac around the heart, respiratory failure, and vision impairment
Genetic and Birth Effects
! Birth defects from radiation include abnormal growth, mental retardation, poorly formed eyes, small head, and childhood cancers.
Teratogenic Effects ! Radiation effects on the fetus
! Common effects include short stature, abnormal organ position, and abnormal organ size
Poor Immunity ! Negative side effects include disrupted white blood
cell activity, poor liver function, inflamed cells, poor muscle mass, and fluid imbalances
Radiation Sickness ! Also called as Radiation Poisoning
! term used to describe the damaging effects of large doses of radiation on the body, such as after a nuclear bomb explosion or nuclear reactor explosion
Nausea, Diarrhea & Vomiting
! Caused by smaller but significant doses of radiation
Psychological & Behavioral Effects
! Complaints among Atomic bomb survivors.
! Neurotic symptoms, including gen. fatigue, amnesia & lack of concentration as well as other symptoms commonly associated with autonomic nerve imbalance, such as palpitation or a sense of burning or chill.
