After the explosion at Reactor 4, curious people flocked on the railway bridge just outside Pripyat to get a good view of the reactor. They were told that radiation level was minimal and that they were safe. In truth, much of the radiation had been blown onto this bridge in a huge spike. They saw the rainbow coloured flames of the burning graphite nuclear core, which were higher than the smoke stack itself. Now they're all dead. They were exposed to over 500 roentgens, a fatal dose.
