I watched this miniseries and found it excellent - despite a few goofs and exaggerations here and there, which might be excusable for varying reasons.

In the second episode, timing of the detection of the incident and some measures taken in the Western World, and that of the evacuation of Pripyat are wrong. First, the process of evacuation decision and its approval by the authorities in Moscow, which actually took place next night (26-27 April), when buses were also sent from Kiev, was completely omitted.

Instead, Shcherbina is falsely shown receiving a phone call next morning (27 April) and sharing the information with Legasov that the Swedish and US authorities have learned all about the accident and that "they are not letting children play outside in Frankfurt" shown in striking contrast with children on the streets of Pripyat. And immediately after that, evacuation buses are shown arriving at 14:00 and beginning to evacuate the town straightaway.

In fact, the Forsmark Nuclear Power Plant in Sweden first detected the extraordinarily high levels of radiation next morning (28 April), Moscow TV broadcast the first news about Chernobyl on that evening and, furthermore, things like closure of children's playgrounds in Frankfurt region (1600 kilometers away) took place only at least a week later in May 1986.

So there's no such thing like the Soviet authorities cared about the children in their country less than the West German authorities cared about the children in their country at the time of Chernobyl as depicted in the second episode.

What a disappointment at the end of such an otherwise very good film, like the other miniseries "When They See US" which in turn reveals the dark side of the state bureaucracy in the United States.

This (and many other minor issues) could perhaps have been avoided if this otherwise very fine miniseries were co-produced with people from Ukraine or Russia as well. The Cold War is over, remember? It's time we all realize we now live in an era of multi-polar world, an era of globalization.
