What really happened – measures taken
After 36 hours:  
     Evacuation of 45,000 people from the city of Pripjat
Until May 5th: 
      Evacuation of 130,000 people from within 30 km of ground zero
May 1st, 1986: 
     The state begins the control of water and milk
23. Mai 1986:

Слайд 5





What really happened – measures taken
The plants‘ fire brigades try to 
	control the flames
600,000 – 860,000 young men
	(so called liquidators) are drafted to clean
     up the wreckage
Until May 5th: 4,200 tons of lead and sand 	
	are dropped on the nuclear reactor
May 6th: The fire is finally brought under control

Слайд 16





Health effects of radioactivity
Low level radiation
Each dose, no matter how small, can cause cancer
The question is how often this occurs and if other diseases can also be attributed to it 
According to new studies, the effects of low-level radiation include: 
Genome instabilities
Mutations of DNA
Malformations
Increased cell aging

Amongst liquidators: Rise in cancer rate by 20 %
     
In the region of Gomel, Belarus: rise in cancer rate by 55,9 %  
In the regions of Gomel and Mogilev: Doubling of breast cancer rates, as well as a shift of 15 years towards younger women
Rise of childhood leukaemia in the affected regions: 300%
Rise of brain tumors amongst small children in Ukraine: 580%

Health effects – other diseases
Liquidators
Increase in lethal cardio-vascular diseases by 22%
Sharp rise in gastrointestinal and CNS-diseases
95% of liquidators suffer from ocular diseases
Accelerated aging due to damage to antioxidant systems
Children
70% of children of affected parents are registered as chronically ill (Ukraine, 1996)
13x rise in childhood diseases in the region of Gomel

Criticism of the IAEA/WHO Study
New and significant studies were ignored.
More than 100,000 people left out of the calculations.
The calculations did not include non-cancer diseases.
5,000 casualties are missing from the original study in the press release.
