  1. Synthèse sur les conséquences environnementales de l'accident de Tchernobyl.

    Fascicule, Rapport - En français

    Traduction en anglais : Summary of the consequences for the environment of the Chernobyl accident.

    The main conclusions on the environmental consequences of the Chernobyl accident in the former Soviet Union can be summarised as follows : - the long term radioactive contamination of the environment can essentially be put down to Cs and Sr and, to a lesser degree, transuranic elements.

    In the short term, the radioactive iodine fall-out plays a fundamental role ; - in the countries of the former Soviet Union, it is estimated that 29,300 and 10,200 km2 of the surface area of the land are respectively contaminated by over 185 and 555 kBq. m-2.

    Approximately 1,064,000 people live in areas contaminated by more than 185 kBq. m-2 ; - acute radioactive fall-out effects have occured in the 30 km exclusion zone, essentially witnessed by the death of numerous conifers.

    On average, it will take about twenty years for half the Cs to disappear from the top 10 cm of soil ; - the level of contamination of food products varies greatly according to soil type.

    However, we can consider that milk, berries and mushrooms were the most critical foods in the years immediately following the accident and that some of the agricultural counter-measures taken have proved very useful in containing the contamination of food products.

    Because of the massive iodine leakage, the worst affeced organ in the body during the months following the accident was the thyroid gland. (...)
