In 1987, Goiânia, Brazil, became the site of one of the world’s most serious radiological accidents after an abandoned medical source containing Cesium-137 was removed from a former clinic and broken open.
Nearly 40 years later, in 2026, we revisit locations connected to the accident and take new radiation measurements.
Some historical scenes depicting the events of 1987 are AI-generated reconstructions and are included for illustrative purposes. All present-day footage is real, and all radiation measurements were taken with the Radiacode 110 — a compact scintillation radiation detector and gamma spectrometer capable of identifying radioactive isotopes such as cesium-137.
