How the Goiania Tragedy Began

Closure of a Private Treatment Facility

In 1985, a privately owned radiotherapy center relocated to a newer site in Goiania, Brazil. The older location was left unused, with demolition delayed due to last-minute legal complications. As time passed, the structure became increasingly rundown, and the possibility that some medical devices had not been moved began spreading among locals.

The building remained partially intact and neglected.
Abandoned equipment inside caught the attention of scrap collectors.

Medical Machinery Left Unsecured

Eventually, two scrap collectors, Roberto Alves and Vagner Pereira, decided to explore the vacant facility. They discovered a heavy, unfamiliar piece of equipment, which they assumed had significant value. Unable to carry the entire device, they removed its largest component—an oddly shaped piece of stainless steel—and transported it home using a wheelbarrow.

After dismantling the object for parts, Alves found a small aluminum cylinder with a glass window. Curious, he broke it open and found a strange, rice-like substance inside. This material soon attracted attention for its eerie blue glow, unknowingly spreading radioactive contamination to multiple households.

List of notable events:

Scrap was sold to a local scrapyard.
The glowing material was shown to family, friends, and neighbors.
Small amounts were distributed throughout the community, increasing exposure.

These missteps set the stage for widespread radiation exposure across Goiania, all stemming from overlooked and unsecured equipment left behind in the abandoned health facility.

Unearthing the Hazardous Apparatus

Salvagers Search the Abandoned Facility

Two individuals, Roberto Alves and Vagner Pereira, entered the derelict remains of a former radiotherapy clinic in search of valuable items. The building had been left partially intact after a move to a new location. They spent hours combing through debris, hoping to find equipment they could sell for scrap.

Breaking Down the Device

The pair discovered a hefty and unusual piece of medical machinery. Due to its size and weight, they removed its most valuable part and transported it in a wheelbarrow. Over three days, Alves painstakingly disassembled the machine at home, encountering robust construction and layers of lead. During the process, he found an aluminum cylinder featuring a small glass window.

Discovery of the Cobalt-60 Core

Inside the aluminum cylinder, Alves encountered a substance that resembled rice grains but crumbled easily into powder. Unaware of the dangers, he broke the glass and handled the contents directly. The material emitted a blue glow, attracting curiosity and leading to its distribution among friends, family, and neighbors, who unknowingly exposed themselves to serious health risks.

Civilian Contact With the Luminous Dust

The distinctive blue glow of the powder attracted attention from the scrapyard owner and his community. Curious visitors handled the material directly, sometimes taking small amounts home. Children played with the substance, even applying it to their skin.

Substance displayed to family, friends, and neighbors
Portions distributed and carried to multiple homes
Individuals experienced symptoms soon after exposure

Examples of Exposure:

Neighboring households visited to observe glowing powder
Powder used as body paint and decoration
Rapid onset of illness among those handling the substance

Movement of Hazardous Material Throughout the City

As the substance passed through various hands and locations, elements of the still-radioactive device were dispersed across Goiania and nearby areas. Metal scraps containing remnants of the powder were sold and transferred between several facilities. This process allowed contamination to reach a significant number of people and a wide geographic area.

Contaminated scraps left scrapyards for other parts of the city
Substances traveled outside initial discovery sites
Only halted when one individual identified a link to widespread sickness

The unintentional transportation and redistribution of the radioactive powder greatly increased the risk of exposure across the city.

Medical Effects and Immediate Treatment Efforts

Early Signs of Radiation Exposure

Individuals who came into contact with the discarded medical device quickly began to experience unexplained health issues. Symptoms appeared within hours or days and included persistent nausea, vomiting, diarrhea, and unusual skin problems such as swelling and rash that resembled burns. The speed and variety of these effects puzzled those affected, especially as many noticed their symptoms worsening after handling the mysterious glowing substance found within the device.

Errors in Initial Medical Assessment

When those suffering from these symptoms sought help, local healthcare professionals misinterpreted their condition. Common diagnoses included food poisoning or allergic reactions rather than radiation exposure, due largely to limited awareness of radiation hazards in the community. This misdiagnosis led to recommendations such as bed rest and routine medications, which did not address the underlying cause.

Symptom Reported Typical Diagnosis Given Suggested Action Vomiting, diarrhea Food poisoning Rest, hydration Swollen, rash-covered hand Allergic reaction Bed rest, medication Severe persistent illness Viral or bacterial infection assumed Rest, home care

First Fatal Outcomes Linked to the Incident

Not long after the initial exposure, the first fatalities from radiation poisoning began to occur. Among those who died were family members and others who had prolonged or direct contact with the glowing material. Distribution of the substance among friends, relatives, and neighbors increased the number of affected individuals, spreading both illness and confusion throughout the community as the scale of the crisis became evident.

Key Discoveries and Immediate Emergency Responses

Maria Ferreira Connects the Dots

Maria Ferreira began to notice a disturbing pattern. She realized that everyone who had come into contact with a strange glowing substance was falling ill with the same symptoms. Despite being assured by medical staff that she had an allergic reaction, Maria trusted her own observations and decided to take decisive action.

Her determination set her apart. Most people in her community lacked knowledge about radiation or its dangers, and her insight would prove crucial in drawing attention to a much bigger issue.

Emergency Notification of Public Health Officials

Faced with growing illness in her family and community, Maria went to the local Department of Health. She brought a bag filled with contaminated items and insisted to officials that these objects were harming her loved ones. At first, medical staff dismissed her claims.
