On 26th of April 1986, 33 years ago, at Chernobyl nuclear plant, Ukraine, there was a terrible accident at the reactor number 4. More than 50 cities, the most important was Pripyat, were evacuated in just 2 days. Unfortunately was too late and most of the population was already contaminated by radiation. Now all reactors are inctive but remains the question disposal of spillage that contaminate hopelessly territory.
