How many people died from the caesium-137 incident in Goiânia? The tragedy that became a global Netflix series

It's one of those things we learn about in school, but over time, it fades a little in the memory. Then suddenly, the whole world starts talking about Goiânia again. The series “Radiation Emergency” exploded onto the Netflix catalogue, entered the global top 10, and sparked that curiosity everyone has but few can properly answer: after all, how many people died from the caesium-137 incident in Goiânia? And what happened to that cursed place?

Let me explain, because I've followed every chapter of this story up close. Not in the 80s, of course, but I've had a front-row seat to the aftermath this disaster left on the streets of the Central-West region. Now, with the series generating so much buzz, it's as if the ghost of caesium has decided to show its face again. And the question being asked most often in pubs, WhatsApp groups, and even in comments from people binge-watching the series is always the same: how many people died from the caesium-137 incident in Goiânia. So, let's set the record straight.

The official number and what it doesn't tell you

If you search on Google right now, the official, cold number that appears is four deaths directly attributed to the contamination. Four people. But anyone from here, anyone who saw that glowing blue dust in a child's hand, knows that number is misleading. It doesn't measure the true scale of the damage.

The four direct fatalities were: Leide das Neves, the housewife who handled the scrap and found the lead canister; Maria Gabriela Ferreira, the six-year-old girl who played with the glow of the caesium and became a symbol of the tragedy; Israel Batista dos Santos, the security guard; and Ademar Alves Ferreira. They died in the first few months, between late 1987 and early 1988. But the stark reality is that the toll was far greater.

If you consider the trail of illnesses, the cancer cases that emerged later, the depression, the stigma, and the suicides of those who couldn't bear living with the fear or guilt, that number rises. Many people speak of dozens of deaths in the following years directly linked to the accident. Caesium doesn't just kill at the moment of exposure. It eats away slowly. And that's the part anyone looking for a guide to understanding the caesium-137 Goiânia death toll needs to grasp: it's not an exact number. It's an open wound.

Where the nightmare happened and what those places are like today

Many people watching the series or reading old articles get curious about the locations. What happened to Rua 57, in the Aeroporto district? And what about Devair's scrapyard? Well, the history lives on in these places too.

The main site, Rua 57, still exists, but it's not the same. After the contamination was discovered, the area became a containment construction site. Many houses were literally scraped away, erased from the map. The soil was removed. What remains? Today, part of that region has been re-urbanised, but the land where the old Goiânia Vigilância building once stood, where the capsule was first opened, remains a silent landmark. It's one of those places you drive past and feel a shiver, even though nothing looks out of place.

If you were to do a review of the current situation regarding the caesium-137 Goiânia accident, you'd see it's not just about the past. The so-called "affected sites" continue to be monitored by the National Nuclear Energy Commission (CNEN). Some areas have been cordoned off for decades, complete with radioactivity warning signs. The prime example is the deposit site in Abadia de Goiás, in the metropolitan region, where all the contaminated waste was dumped. That place has become an open-air nuclear cemetery. Only authorised personnel with measuring devices are allowed in.

What the series "Radiation Emergency" changed about Brazil's perception

What really got to me was seeing the series break through the bubble. It was reported in the press that it entered Netflix's global top 10. And honestly, I thought no one outside of here cared about this anymore. But the world was shocked all over again. Even those who usually follow viewing trends commented that it had a strong debut, even going up against fans of a certain South Korean group everyone knows. And why does this matter?

Because the series, with its suspenseful and accusatory tone, brought back a pain we try to forget. And it brought a new wave of people, not from Goiás and who didn't live through it, asking: how many people died from the caesium-137 incident in Goiânia? What was just a paragraph in a textbook has become a topic of debate on social media.

And you know what's even stranger? Seeing the people of Goiás themselves commenting. There are people living in the Aeroporto district today who had no idea they were walking on the very ground where Leide found the device. There are young kids who only now understood the gravity of it, seeing the story turned into entertainment. It's strange, but it's also educational.

The legacy: more than just numbers

When people ask me if we've "moved on" from caesium, I say no. We've learned to live with the scar. If you look at the measures Brazil implemented afterwards, it was a watershed moment. The law prohibiting the scrapping of radioactive equipment, the creation of emergency protocols – all of that came after 1987.

But what strikes me most, and what I think everyone reading this guide should take to heart, is this: it's pointless to know how many people died from caesium-137 in Goiânia if you don't understand what they represent.

• Leide: the accidental discovery, a mother just trying to make a bit of money.
• Maria Gabriela: the innocence that paid the highest price for a pretty glow.
• The scrap collectors: the invisible faces of a country that didn't look at its own waste.
• The neighbours: entire families forbidden from taking anything from their homes, because even the clothes on their backs were condemned.

So, the next time someone asks you how many people died from the caesium-137 incident in Goiânia, you can say: "four died in the first few months, but the disaster destroyed the peace of an entire city." That's what the series, at its best moments, tries to show. And it's what we, who love this Goiânia with its scorching sun and welcoming people, can't let become just a number in a cold statistic.
