April 17, 1996: Worker checks radiation levels inside Chernobyl nuclear power plant

April 17, 1996: A worker at the Chernobyl nuclear power plant takes a reading of radioactivity inside the "tomb" encasing the ruined fourth reactor. Readings here in 1996 were 800 roentgens per minute, one-tenth of what they were by the "elephant's foot" - the tangled mass of concrete and steel at the right of the nuclear fuel which melted in the accident.
