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

It’s one of those things we learn in school, but with time, it fades away in our memory. Then, suddenly, the whole world starts talking about Goiânia again. The series “Radioactive Emergency” exploded onto the Netflix catalogue, landed in the global top 10, and sparked that curiosity everyone has but few can answer properly: so, how many people actually died from the caesium-137 accident in Goiânia? And what became of that cursed place?

Let me share this with you because I’ve been following this story up close. Not in the 80s, of course, but I’ve seen the lasting impact of this disaster on the streets of the Central-West region. Now, with the series generating so much buzz, it feels like the ghost of caesium has resurfaced. And the question you hear most at bars, in WhatsApp groups, and in comments from people binge-watching the show is always this: how many people died from the caesium-137 accident in Goiânia. So, let’s get the facts straight.

The official numbers and what they don’t reveal

If you Google it right now, the cold, official number that pops up is four deaths directly attributed to the contamination. Four people. But for those of us from here, who saw that blue dust glowing in a child’s hand, we know that number is misleading. It doesn’t capture the full extent of the damage.

The four direct fatalities were: Leide das Neves, the housewife who handled the scrap and found the lead casing; Maria Gabriela Ferreira, the six-year-old girl who played with the glowing caesium and became the 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 plain truth is, the toll was much higher.

If you factor in the trail of diseases, the cancer cases that emerged later, the depression, the stigma, and the suicides of people who couldn’t live with the fear or guilt, that number goes up. Many say there were dozens of deaths in the following years directly linked to the accident. Caesium doesn’t just kill instantly. It eats away at you slowly. And that’s the part anyone looking for a guide on how many people died from the caesium-137 accident in Goiânia needs to understand: 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 neighbourhood? And what about Devair’s scrapyard? Well, the story also lives in these places.

The main spot, Rua 57, still exists, but it’s not the same. After the contamination was discovered, the area became a decontamination construction site. Many houses were literally scraped away, wiped off the map. The soil was removed. What’s left? Today, part of that area has been redeveloped, but the land where the old Goiânia Vigilância warehouse stood, where the capsule was first opened, remains a silent landmark. It’s one of those places you drive past and get a shiver, even though nothing looks wrong.

If you’re looking for a review of how many people died from the caesium-137 accident in Goiânia regarding the current situation, you’ll 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 remain isolated for decades, with radioactivity warning signs. The prime example is the Abadia de Goiás repository in the metropolitan region, where all the contaminated waste was dumped. That place became an open-air nuclear cemetery. Only authorised personnel with measuring devices can enter.

How has the series "Radioactive Emergency" changed Brazil’s perspective?

What really got to me was seeing the series break out of its bubble. It was reported that it entered Netflix’s global top 10. Honestly, I thought no one outside here cared anymore. But the world is shocked again. Even those who usually track viewership trends noted it had a strong debut, even up against fans of a certain South Korean group everyone knows. And why does this matter?

Because the series, with its suspenseful and critical tone, has brought back a pain we try to forget. And it’s brought a new audience, people not from Goiás and who didn’t live through it, to ask: how many people died from the caesium-137 accident in Goiânia? What was just a paragraph in a textbook has become a topic of debate online.

And you know what’s even crazier? Seeing the people of Goiânia themselves commenting. There are folks living in the Aeroporto neighbourhood today who had no idea they were walking on the same ground where Leide found the device. There are young people who only now understand the gravity of it, seeing the story become 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 turning point. The law banning the scrapping of radioactive equipment, the creation of emergency protocols—all of that came after 1987.

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

• Leide: the accidental discovery, a mother just trying to make some extra money.
• Maria Gabriela: the innocence that paid the heaviest price for a pretty glow.
• The scavengers: the invisible face of a country that didn’t pay attention to 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 accident in Goiânia, you can say: "four in the first few months, but the disaster killed the peace of an entire city." That’s what the series, at its best, tries to show. And that’s what we, who love this sunny, welcoming Goiânia, cannot let become just a cold statistic.
