How Kodak Exposed The Atomic Bomb

Veritasium - 2020-09-16

Kodak detected the first atomic bomb before anyone else figured it out. Then they made a deal not to tell anyone. Thanks to HBO Max, and their new show raised by Wolves for sponsoring this video! https://rb.gy/alghwn

I’m a thyroid cancer survivor who was born in 1954 on a dairy farm and drank raw milk ever day. The Ozarks region is in the area of highest exposure. I’ve wondered what caused it and I believe this video has the answer. I lost half my voice box to the cancer surgery.

I'm surprised no one has used this as a premise for a sci-fi time travel story. Device that detects fellow time travelers by their strontium-90 level.

@Jackspedicy well anywhere that there was nuclear tests so Russia to

JonatasAdoM - 2021-09-07

That's why only Americans and American steel has traces of raditation right?

StormyStrife - 2021-09-27

"Time Travel was never possible, that is, until massive amounts of Stronium-90 were seeded all over the continental united states in the time around 1950-1960, but thanks to thousands of tests by the then-United states of America, we can freely hope to and fro without much effort, although I'm to too sure about causality, it's never been safer, while jumping to past eras is like jumping off a cliff blindfolded, you might land in many of the pools, or you might hit solid ground"

You could have the explanation that they're detecting Strontium-90 through time and that's how they get the 4th Dimensional coordinates that also likely use the quantum entanglement features of those isotopes, it found in this sci-fi future that quantum entaglement works across time as well as space.

My grandmother was a secretary for a general in the 1940’s. She witnessed Trinity in person as well as a test in the Pacific a year later. She gave birth to my mother just over a month prior to Trinity. My grandmother died from cancer at the age 41. My mother developed cancer in her early 40s as well.

Matty Vlietstra - 2022-02-16

@Staggeredgore99 I don't think the amount of radio active fallout poses much of a health risk these days as the half lives of the radioactive isotopes that were created in the blasts have been and gone, but it is still detectable and higher than the naturally occurring radiation. I'm not an expert though so I may be wrong

George Olson - 2021-12-28

As a child in Calgary I noted an article in Time or News Week that gave a map of the radio active fallout plumes from Soviet tests in the Arctic island of Nova Zemla. It also left out any data for Canada. It interestingly showed high levels in Alaska (no surprise) and about 1/2 the level in Montana. Note this pattern flowed into the Yukon and Northwest Territories then turned south along the East front of the Rocky Mountains toward Montana while spreading out Eastwards. My conclusion as an 8 year old was infuriation that the Canadian Goverment in Ottawa was lying to us in Alberta and the milk I was drinking was contaminated. In 1960 at age 10 I moved to Brisbane Queensland so I was only further contaminated in a much much lesser way by a very few French tests in the South Pacific which had to travel around 5/6ths of the
planet to reach our Queensland coastal pastures. The map from this video shows that I was also exposed to flow North along the Rocky Mountain Front of contamination from U.S. tests in the 50s
Well fingers crossed -- so far -- cancer free in my 72nd winter.

Let's hope you keep it up and get to your 73rd, and many winters after that!

SSM24 - 2021-07-21

Keeping radioactive nuclear fallout a secret from the public in order to protect the interests of large corporations has to be the most American thing I've ever heard.
EDIT: Since I've gotten a few replies about it, I do want to point out that yes, I'm aware that this doesn't really represent the situation accurately. I just thought it was funny, that's all.

Ilya Karuseichyk - 2021-09-14

@Max Robley nice word "national interest"? Is this interest about dying of cancer?
Behaviour not quite different from USSR where noone cares about people, but only about stupid competiton with USA

Max Robley - 2021-09-15

@Ilya Karuseichyk I’m not saying I agree with it. I’m simply stating that it was not kept a secret to protect the interests of private companies, but rather the interests of the US.

Ilya Karuseichyk - 2021-09-15

@Max Robley That's sound more true. "National interest" sound like interest of the people

The Smuggest - 2021-09-23

@Ilya Karuseichyk National interest is the interests of a nation. I think you're just confused about the interest of the public/people. Ngl I would be too.

christopher békési - 2021-12-06

@Neil gelinas It's not just about the gov as a whole, this is more about parts of the government that have been assigned secrecy through a massive lie, so no one can check them and make sure they don't do anything illegal, which will definitely mean that they are going to take illegal actions. The NSA is an exact example of that in modern times. The gov in terms of courts and the supreme court who's meant to keep them in check probably knows about it since they haven't conducted a proper investigation even though they have already been under trial.

avishi Shalom - 2021-12-20

Thank you very much for your very much appreciated work and for having the courage to bring these important things to the attention of the general public

dreska - 2020-09-16

I also want to mention the low-background steel. As modern steel is processed using atmospheric air, any steel produced after the testing has significant amount of contamination from radionuclides. However, steel made before Trinity doesn't and therefore has got an application in radiation sensitive equipments such as Geiger counters. This type of steel is usually salvaged from ships that sunk before 1945. There is a Wikipedia article about this with some references at the bottom, and you can probably find more info on the internet.

Ethereal Rose - 2021-12-27

@Eric The Epic lol

More oil naturally seeps through cracks in the ocean floor bed in a day than 10,000 sunken ships

Get over it

Eric The Epic - 2021-12-27

@Ethereal Rose This comment is pretty confusing, because you talk like you disagree with me, but you actually agree with me. Also doubly confusing is that I was in a reply thread like a week or two ago that was also about sunken ships, fuel oil, and desecrating graves, and... wow. Exact same conversation. Genuinely thought this was from that thread.

Thanks for the history lesson here. (I hail from “Kodak country” in Rochester, NY, USA 🙂.) Also, thank you so much for pointing out the recklessness of the government in not protecting its population from the tests. I do think you give the US government too much credit in not understanding the danger.

The Trinity test sight in my homestate, NM, is periodically open to tourists. It is said to be near Alamogordo(over a hour away) despite the NM town, Carrizozo being right next to it. Locals alive at the time described the atomic detonation as a rising sun.

Extremely fascinating. An uncle on my wife's side of the family was a chemist at Los Alamos during the war. He witnessed the trinity blast. After the war, he went on to work at Kodak for thirty plus years. Too bad he is no longer living, would love to have shared this with him.

Eric - 2021-11-09

I know this is an old video but I'm still relevant damnit! Back in 2011 a month or two after the Fukushima Nuclear disaster my Health Physics advisor and myself gathered rain water samples and ran them through our school's HPGE detector in Pennsylvania. We found significantly greater levels of I-131 in the rain water( I cannot remember the exact values). This was a direct result of the powerplant disaster. Our data was verified when a Berkeley, CA study was conducted and found even greater levels in their rain water. This was due to them being closer to Japan. Plume dispersion of radioactive fallout travels the globe.

WaterlooExpat - 2022-01-01

7:00 The US government, agreeing to provide Kodak, with advance warning of upcoming nuclear tests, answers a question that has circulated within our family for decades. My paternal grandfather worked at Kodak, in Toronto, Ontario, for over 40 years, retiring in 1967. Although the tests were officially secret, Kodak Canada somehow received notice of impending blasts. The workers were instructed to place large sheets of lead over the sheets of photographic X-ray film. The film was protected, by this means. If the lead sheets were not placed, the radiation would get trapped in the morning dew, on the roof of the Kodak factory, and then pass through six concrete floors and damage the film. If this process was not followed, the film had to be discarded.

@Edgars Godjuks What a dumb argument. This isn't an accident that couldn't have been prevented. This was done in top secret because they knew very well what they were doing would have been strongly opposed by the people. If people would have known the truth, they wouldn't have let it go on.

If Cerium 141 could only be made in a nuclear fission reaction, then how was it well characterised enough that the person at Kodak could identify it? It had to have been a well known isotope

­ - 2021-12-30

They probably knew such an element could be created in the process, and with a good model, they could have figured out roughly what it's properties were. Mandeleiev predicted multiple elements and their properties that way before they were even discovered.

@dirty pure they could've cared more about safetey. When they do not know much about it, just treat it as if it's dangerous and be careful from the start and act according to what was advised, ie testing in the East coast, but they chose convenience over proposed safetey. It's really naïve to treat something with unknown properties with such carelessness.

I find your channel very interesting and easy to share. one thing I have debated with some friends over the years, was their belief the atomic bomb was just tnt and it always has been. on TV and any test video footage etc, just more tnt... they argue that the physics and manipulation of matter could potentially be done in a stable environment but would always fail because mans ability to contain and control 100% of the result, and then, dropping it from a plane just silly...and they believe that was TNT too.

what would you say to them that is empirical proof? invisible fire not enough?
i am really into understanding quantum,time,dimensional awareness and science we can debate.

Shawn German - 2022-02-16

Isn’t it strange how the map representing the radioactive fallout, shows that it abruptly stops at the northern border with Canada… how smart that fallout is to know that it was from the US and shouldn’t impact other countries…

Rarest Form - 2021-09-10

I thought this was going to be about how the Kodak company developed film capable of high density light exposure from blasts. Joke's on me, instead found out I've got the remnants of nuclear tests from decades ago.😂

C Irby - 2021-08-24

Oh, my wife's first cousin who graduated high school in ~ 1968 did his senior science project on Kodak film. He found a "mistake" in their film and development process. Kodak sent him to Harvard on full scholarship. Harvard Med School was next and he became a cardiologist - but not JUST a cardiologist. He founded a company producing next generation blood thinners and sold it for $200 Million. He rolled that into founding another company and sold it two years later for $350 million. He's now the chief of cardiology in a large west coast hospital. And, yep, he still has his southern drawl and an "aw shucks" laid back personality.

That last tidbit was quite possibly the most horrific thing I've heard. I get it won't hurt me, but nuclear weapons are able to change us for generations and people still think they are just big bombs .

Sciencerely - 2020-09-16

As a biologist and just watching the video I think we should be jealous of the organism called Deinococcus radiodurans. This bacterium is able to completely repair its shattered chromosomes after being exposed to high levels of radiation (which cause DNA breaks). While humans experience neurological damages after being exposed to radiation of roughly 30 Gy, D. radiodurans can survive over 10000 Gy, since it is able to very effectively connected fragmented DNA (I'm just making a video about human DNA repair systems). Great video so far!

Howard Higgins - 2021-08-10

Sometime during the 1970's or '80's, Proctor & Gamble were attempting to build radiation detection chambers for their research labs in Cincinnati. Not matter what they did, they could not eliminate the background radiation inside the test vessels. The problem they found was that any steel used in the casings, no matter what year it was procured contained radioactive particles.
Finally, to secure a particle free source they searched the US for steel stocks originally produced before Trinity, and not re-manufactured since. They still had to acid-wash the rust off the outsides of the steel plates, as the rust was also found to be radioactive.
According to a top research chemist at P&G that I spoke with, finding this steel was VERY difficult.

Buckhorn Cortez - 2021-12-30

So, you're telling me that the raw taconite mined and shipped for new steel is radioactive? Hard to believe...

James Wills - 2021-12-23

Nearly forty years ago I had a lecture from "Cal V....", a Kodak engineer who had as a Kodak engineer previously supervised the surveillance of Cuba before the Cuban Missile Crisis. He told us that, since black and white photographic paper had an infinite "MTF," modulation transfer function, the simplest way to visualize the pictures were to magnify the whole roll until it was big enough. They built a special twenty-foot high room with two, two-story long rollers standing vertically in one corner, magnified the original picture rolls to two stories high, and fed the roll of film off one roller, around rollers in the other three corners, and then back on the second corner roller. Women (They used women because their abilities to see detail were better.) walked around the room, with a second group walking around a scaffold placed halfway up the roll of film, and looked for anything out of the ordinary. The rest is history.

Great video! Isn't the Trinity site still radioactive? I would assume the other radioactive elements produced with half lives in the thousands of years are still on site.

People aren't allowed to linger long near the original ground-zero to this day.

I am greatly appalled by the Truth reported here about the horrific effect of the atomic bomb tests on human beings, in particular and all of life, in general.

So much ignorance; so much arrogance; so much disregard of the welfare of beings for the sake of creating a weapon of mass destruction.

I am still processing what I’ve seen and heard. Still trying to make sense of it all.

excellent coverage of the issue.. that you considered the human consequences in your video is laudable.

I was expecting to see how Kodak set up its cameras to capture pictures of the explosions. This was even more interesting than that.

I appreciate all the information you bring under the light with this video. - However, it would seem you have mistitled the video, because as you clearly state, kodak did NOT expose it. They found out, but kept silent.

Its a pun .........it was the radiation that "exposed" and ruined their film, like an x-ray ,think about it .............................Erik

The scientists involved in the first nuclear test were not 100% sure if the bomb would ignite the atmosphere or not.
They decided that it was worth the gamle.... luckily it did not happen, but then again if it had there would not been anyone left around to blame them.
Scary but true.

Specialist: Advises the military where to safety conducts tests.
Military: Lets do the opposite.

Harsh Sharma - 2021-08-28

its pretty ironic that the military is for the safety of the people

i bet the army was in charge of the placement

This is pretty much how government mishaps happen. Experts tell the government to do something, government doesnt listen.

Nothing surprising!

Maybe a neighbor they despised came from there or something, you know, they chose Hiroshima and Nagasaki for similarly dumb reasons.
