The other thing I will add is that the miniseries drew
  heavily from Svetlana Alexievich’s master work ‘Voices of 
  Chernobyl’, which I cannot recommend enough.

I think the book's title is "Chernobyl Prayer" and may be "Voices of Chernobyl" is the subtile. The edition (from Penguin) I am reading currently just has the title "Chernobyl Prayer". I haven't watched the series, but can't recommend the book enough, especially in these testing times where it is hard to get a good grasp of the situation unfolding. Sadly (as the book narrates) most of the people on the ground who were first deputed (forced) to carry out cleanup activities in the aftermath of Chernobyl were ill equipped, and many got exposed to high levels of radiation resulting in devastating consequences. This is not very different from the risks that many frontline workers fighting the current pandemic have to bear with.
