Instead, a single abandoned radiotherapy unit set off a chain of contamination that spread cobalt-60 across half of Mexico and into the United States, exposing an estimated 4,000 people and forcing the demolition of hundreds of buildings. How a Life-Saving Machine Became a Hazard      In November 1977, the private Centro Médico de Especialidades in Ciudad Juárez purchased a Picker C-3000 teletherapy unit from a U.S. company. The machine contained a sealed source of cob...
