The nuclear accident at Chernobyl on April 26, 1986 had a heavy impact on life, health, and the environment. Some five million people continue to live in areas contaminated by the accident and have to deal with its environmental, health, social and economic consequences. There are three main environmental components where it definitely based: in the soil; in the air; in the water. The liquidators tried not to let the rain fall over the exclusion zone. Tepco was not permitted to control flow by extracting groundwater before the point of contamination and discharging to sea. Assessment of the environmental contamination and the resulting radiation exposure of the population was an important part of the International Chernobyl Project in 1990–1991. After the 1986 Chernobyl nuclear accident, reactor number 4, which was involved in the accident, was encased in concrete to contain the radiation and debris, creating a structure known as “the sarcophagus”. 0 Reviews. This contamination occurred after the Chernobyl explosion and currently persists. In some European countries the contamination of rivers and lakes has caused problems, for example in Switzerland and Sweden, where this is a relatively serious problem. One particular subject for concern is the possible contamination of groundwater in the exclusion zone by strontium 90, which might result in the contamination of drinking water at a rate well above the acceptable limits.
