The Goiânia Accident: A Deadly Glow In Brazil

The 1987 Goiânia Radiation Incident: Analysis of an Orphan Source DisasterExecutive SummaryThe Goiânia radiation accident, often referred to as "Brazil's Chernobyl," was a catastrophic radiological event triggered by the theft and dismantling of an abandoned medical teleotherapy unit. In September 1987, two scavengers unknowingly breached a stainless-steel capsule containing 19 grams of highly radioactive Cesium-137 chloride. The subsequent distribution of the material among family, friends, and the general public led to a major health crisis and environmental contamination.The disaster resulted in four confirmed deaths, over 20 hospitalizations, and the significant contamination of 250 individuals. Public panic necessitated the screening of 112,000 people. The cleanup operation generated 6,000 tons of radioactive waste and required the demolition of multiple homes. This incident is characterized by a series of institutional failures—ranging from abandoned medical facilities to regulatory negligence—and eventually led to a global overhaul in the management and registration of "orphan" radioactive sources.
