Episode 3

S1 E3: Guy Martin leaves Russia for the site of the 1986 Chernobyl disaster in Ukraine to explore the record-breaking engineering solutions designed to make the area safe. After receiving specialist training about how to avoid contamination, he is allowed into the most radioactive place on earth, a restricted exclusion zone of 1,000 sq miles. He heads straight for the breached reactor, which is now entombed within a 36,000-ton shelter, and climbs to the top of the structure to carry out a radiation survey.
