In all over In all over 600,000 workers, known as 600,000 workers, known as “Liquidators,” came to clean up the plant sites “Liquidators,” came to clean up the plant sites over the next few years.

They were charged with clearing rubble from the area of the explosion as clearing rubble from the area of the explosion as well as with constructing a concrete shell, called a well as with constructing a concrete shell, called a sarcophagus, around the reactor complex in an sarcophagus, around the reactor complex in an effort to contain radiation. There is little doubt effort to contain radiation. There is little doubt that their self-sacrificing work helped to prevent that their self-sacrificing work helped to prevent the further spread of radioactive materials.

All of these Liquidators were exposed to high levels of these Liquidators were exposed to high levels of radiation, and many have either died or suffered radiation, and many have either died or suffered illnesses as a result of their exposure.illnesses as a result of their exposure.

Sadly, when the Soviet government Sadly, when the Soviet government dissolved, so did their promises of free health care dissolved, so did their promises of free health care to the Liquidators.
