Chernobyl: The New Evidence
7.30pm, Channel 4
Here’s the second big Chernobyl documentary to air over recent weeks (see also Sky’s Chernobyl: The Lost Tapes). The world’s largest nuclear disaster to date is understandably an endless source of fascination – but Russia’s capture of the plant in February means a more urgent interest in revisiting the event to help contextualise the war. This two-parter reveals formerly secret KGB files that show cover-ups before and after the explosion, and speaks to key witnesses including a KGB general, firemen and a reactor worker.
