The Happiness of All Mankind

S1 E4: As mandatory evacuations in the exclusion zone begin, Shcherbina and Legasov bring in General Tarakanov for advice on the use of remote-controlled lunar rovers to remove debris too radioactive for human contact. A young draftee, Pavel, arrives at a military camp, where he's shown the ropes by Bacho, an Afghan war vet. Khomyuk faces government-censor hurdles as she tries to obtain documents related to Soviet nuclear plants, and at the hospital, tries to persuade a critically ill Dyatlov to explain what happened the night of the explosion. When the radiation proves too dangerous for lunar rovers, Legasov and Shcherbina devise a plan to use men to remove debris with the least possible exposure.
