The radiation not only affected the surrounding areas but was carried by rain clouds to places as far away as Great Britain and Sweden. A Chernobyl Forum of international expertise was established to reach consensus on the environmental consequences and health effects attributable to radiation exposure arising from the accident. In a study published today (April 22) in Science, researchers found no evidence for transgenerational genetic effects on the children of people exposed to the accident’s radiation. The area of the dead forest adjacent to the Chernobyl industrial site from the west reached 400 hectares during the subsequent autumn-winter period. 0. Le corps réagit en plusieurs temps lorsqu’il est exposé à des doses importantes de radiations (une irradiation d’origine externe). Radiation sickness. C’est la phase prodromale», explique le chercheur de l’IRSN. A scientist from NUI Galway recently took part in a research at the Chernobyl Exclusion Zone in Northern Ukraine, to investigate what effect the 30 years of exposure to radiation has had on the soil’s microorganisms.

Moreover, understanding the effects of Chernobyl may help humanity react to other nuclear power plant accidents. You may wonder how, exactly, radioisotopes (a radioactive isotope) and mutations are connected. The energy from radiation can damage or break DNA molecules. If the damage is severe enough, cells can't replicate and the organism dies. At Chernobyl, 134 liquidators quickly developed radiation sickness, and 28 of them died from it. Skin just slips off.
