Illustration showing nuclear Reactor Number Four of the Chernobyl Nuclear Power Plant, Ukraine, exploding on the 26th April 1986. Around 1000 square kilometres of land were directly contaminated by radioactive fall-out. A concrete sarcophagus was built to contain the radioactive materials, but within the restricted area the radiation is still lethal to humans. The material inside the sarcophagus will remain dangerous for thousands of years.
