Express.co.uk: Did the KGB try to cover up Chornobyl or silence people?

HBO and Sky series Chernobyl follows the 1986 disaster that pushed Europe to the brink of a nuclear winter and threatened to make the continent uninhabitable. Over the course of the five episodes, viewers saw the nuclear explosion at the power plant, the fallout as well as the events leading up to the disastrous explosion. Chernobyl also gave audiences an insight into the conditions of living in the USSR during the Eighties as well as the denial around the accident.
