The HBO show depicts events very close to the official soviet version of accident which was presented at IAEA meeting in Vienna in 1986 with Legasov as the head of the soviet delegation and which was used as the source for INSAG-1 report. As Legasov says in the show, many things they presented in Vienna were lies which put the blame on the operators to hide ...

This seems to be the beginning of the evacuation announcement which you can also listen to, repeating the first two words, which sound like a repetion of внимание (engl. attention) - there is an audio clip, too. So, in the trailer, it's just Attention, Attention The original announcement (April 27, 1986) then went on For the attention of the ...

Are these two events related? Not entirely. As you say, Anatoly Dyatlov is asking people to go and make sure water is pumped into the core because he is under the illusion that the core is undamaged and that it needs water to prevent a classic meltdown. This is where (even when the fission reaction is shut down) the decay of unstable fission products ...

It seems accurate and not an invention of the HBO series based on these and other references. From the Wikipedia entry on Chernobyl: However, a dosimeter capable of measuring up to 1,000 R/s was buried in the rubble of a collapsed part of the building, and another one failed when turned on. All remaining dosimeters had limits of 0.001 R/s and ...

We don't have the perspective of Legasov in the photo you show here, we are behind him looking ahead at the path of the helicopter, while he is more able to look down. Helicopters often have windows that extend quite low. It's possible he is able to look down at an angle on the roof of the building they are approaching. Graphite is a very dark, almost ...

He was being observed by KGB - you (and so did Legasov) could see an agent watching him from the car. If he simply left the tapes in his flat, there would be found and destroyed when militia/KGB would check on him and found his body. By leaving them outside, presumably in a place that his friends knew about, he was sure that they will be heard by a wider ...

Oops, should have checked Wikipedia first. According to Wikipedia, the HBO version seems more accurate than Midnight in Chernobyl. [https://en.wikipedia.org/wiki/Chernobyl_disaster#Conditions] The test plan called for a gradual decrease in power output from reactor 4 to a thermal level of 700–1000 MW.[41] An output of 700 MW was reached at 00:05 on 26 ...

The quick drop from 725 MW to 512 MW in 22 seconds didn't happen. According to logs the power was gradually reduced by operators from 720 MW at 00:05 to around 500 MW at 00:28 in a span of 23 minutes. RBMK reactor originally had automatic power control system which consisted of two automatic regulators AR-1 and AR-2 (one is active and another is backup) ...

The measuring instrument used for the first ambient dose rate measurements on site was a Russian DRG3-02 (ДРГЗ-02) scintillation counter. Similar devices are still available today (picture taken from zapadpribor.com; I am not affiliated with that site). You can see that it has two scales: 0–3 and 0–10 microroentgens per second (µR/s). Using the little ...

It is quite possibly SRP-68-01 According to the specifications it has the range up to 3000 mR/h but with the tolerance +/- 10% (according to other sources it is even +/- 20%) and the scale going slightly above 3, it is possible to read (with a doze od error) the maximum value as around 3.6. This particular model is mentioned in the book "Radiation And ...
