The most dangerous grave in the US is made up of lead and concrete: The Cold War disaster that left America with its only grave that can never be exhumed

A unique grave at Arlington National Cemetery holds a serviceman lost in the US's first fatal nuclear accident. This burial site is sealed in lead and concrete due to radioactive contamination from the SL-1 reactor incident. The experimental reactor exploded in Idaho during the Cold War, killing three young servicemen instantly. One serviceman, Richard McKinley, was buried at Arlington after the tragic nuclear disaster occurred.
