Ciudad Juárez cobalt-60 contamination incident
1984 Mexican radiation incident / From Wikipedia, the free encyclopedia
A radioactive contamination incident occurred in 1984 in Ciudad Juárez, Mexico, originating from a radiation therapy unit illegally purchased by a private medical company and subsequently dismantled for lack of personnel to operate it. The radioactive material, cobalt-60, ended up in a junkyard, where it was sold to foundries that inadvertently melted it with other metals and produced about 6,000 tons of contaminated rebar.[1] These were distributed in 17 Mexican states and several cities in the United States. It is estimated that 4,000 people were exposed to radiation as a result of this incident.[1]
