Chernobyl's accident

Chernobyl, 35 years later 

35 years after the Chernobyl nuclear accid​​​ent which occurred on 26th April 1986​ in Ukraine, we outline the last information of the situation on the following topics :​

The Chernobyl saf​ety of site facilitie​s (PDF file),

The radioactive waste resulting from the accident (PDF file),​​​​

The large fires in the Chernobyl region (origins and environmental consequences) (PDF file)​​​,

The effects of the Chernobyl and Fukushima accidents on ecosystems (PDF file).​ ​​​

Ten key data sheets

Chernobyl 10 key data sheet 1. The radioactive particles released during the explosion of the reactor were blown over thousands of kilometers by the wind

2. Air contamination levels were significantly different depending on the geographical area and changed rapidly between 30 April and 5 May 1986

3. The deposition of radioactive particles is enhanced during rainfall

4. Deposition across France, and throughout Europe, is highly uneven

5. Contamination of foodstuffs was determined by the date of the accident and deposition characteristics

6. After deposition, the contamination level of farm produce fell at variable rates

7. Since 1987, the contamination of farm produce has fallen faster than the radioactive decay of caesium

8. Special cases concerning more sensitive products

9. Mean doses received by the French population from the Chernobyl accident were low

10. In France, the issues raised about how the accident affected health concern thyroid cancer
