Total
Body Radiation TBI
Data
on TBI is gathered from radiation accidents (Chernobyl, 3 Mile Island,
Los Alamos) and from animal models.
We
are constantly being irradiated :
External
:
- Terrestial radiation (RADON) / .05
rem per year
- Cosmic radiation / .05 rem per year
Internal
:
- Carbon 14
- Radon in lungs
- Radioactive potassium
- .025 rem per year
Medical
exposure :
In
the U.S. we get from .075 to 5 rem per year / average = .125 rem
per year
What
happens when people get a high one shot TBI :
Radiation
sickness
Symptoms
:
- headache
- dizziness
- malaise
- abnormal taste and smell
- NVD
- Decrease in BP and WBC’s and platelets
- Insomnia
Among
the people irradiated survival or death depends on the dose received
:
3
– 5 Gy – 50% of this group will die because of bone
marrow damage within 2 months
10
– 50 Gy – no survivors. They die from GI damage
in 1 –2 weeks
100
Gy – no survivors. Die from CNS damage in hours
to days.
Among
the survivors they will either display Somatic Effects and Genetic
Effects.
Somatic
Effects (happens to the persons own body) :
Early
effects : NVD syndrome, fever,chills, fatigue, hemmoraghing, ulcers,
blood count suppression, they are extremely prone to infection
Late
effects :
Radiologic aging – they look older than stated age
Radiation carcinogenesis – develop leukemia, thyroid cancer, bone
cancers, lung cancers
Permanent sterility
Bone deformities
Cataracts
Overall life shortening
Who
survives depends on age
Young children moght have slow bone development
and boys might become sterile
