In the nearby town of Prypiat, Ukraine, people woke up to respiratory distress and nausea. Emergency response workers encased the reactor in a concrete sarcophagus and, unprepared for exposure to radioactivity, became stricken with severe symptoms of radiation poisoning. Tens of thousands of Soviet citizens filed into Chernobyl to help, considering it their patriotic duty; all were exposed to dangerous levels of radiation with no warning from the government. It took two days for the explosion to be announced, in vague terms, on the national news; not until Sweden discovered a radiation cloud that had drifted across Europe was the true extent of the Chernobyl explosion revealed.

Reactor 4 may not have been the only thing that exploded that day.
