21. Read the article and answer the questions below: The Truth about Chernobyl

A series of explosions shook the plant. About 700 tons of graphite and 70 tons of uranium fuel from the core of the reactor, all lethally radioactive, spewed onto the tarmac and the roof of the turbine hall. Another 50 tons of fuel evaporated, releasing 10 times as much radioactivity into the atmosphere as was released at Hiroshima.

Yet so sure of themselves were they, that for 17 hours after the blast, the power station management insisted that the reactor remained intact and that it was only an emergency water tank that had exploded.

It should have been a simple matter to check, but the dosimeters for measuring radioactivity were locked in a safe and the panel in the control room was dead. The managers refused to believe the word of a physicist who inspected the plant, and who was to die of radiation sickness a few days later. Instead, they relied on machines which had a maximum reading of one five-thousandth of the dose some were actually receiving ...

Some workers received lethal doses because the rest of the site was not evacuated. Night fishermen fished at the outflow to the power station until morning, by which time they were dizzy, vomiting constantly, and their skin had acquired a nut-brown nuclear tun.

There was no evacuation from the company town of Pripyat, where 50 000 people lived, for 36 hours. A man in Pripyat sunbathed on his balcony throughout the next day. Later that evening he was taken to hospital, vomiting uncontrollably.

Why didn't the managers stop the reactor?

What were the consequences of the blast at the station?

What were the consequences of the explosion for the company town?
