I think it showed the very worst failings of communism. The denial mindset was staggering.
What really surprised me, was the apparent lack of understanding of the risks among the general populace, even the firemen, despite their connections with the nuclear plant.
Even my basic traing in such matters had me filled with horror at what unfolded. The dose rates, in roentgens, were the stuff of nightmares.
I am filled with admiration for the selfless courage of those who understood their impossible position and still did their best to cope with the consequences of the disaster.
