That moment at 34 minutes about still births. That hit close to home. Dad was stationed in Nagasaki during the Korean conflict. Nobody talks about changes to their children's health from radiation exposure. Two kids with ADHD and one with severe Autism. I was sent to Enewetak Atoll during the radiation cleanup mission years after the testing had ended. I have a child with paranoid schizophrenia and one that was stillborn. These invisible scars felt by the Marshall Islanders are testiment to our nuclear weapons program. Unfortunately, these scars are also shared within our Veterans community from exposure during cleanup activities. Mostly within the Corps of Engineers doing the heavy work.
Oh no not adhd and autism, those almost never happen without nuclear weapons. Who was diagnosing anyone with either of those in he 50s and 60s? By the time the Korean War rolled around both hiroshima and Nagasaki had no more radiation than background. Stop making shit up to sound special, you're not.
Fantastic video. Great thumbnail, good storyline and flow, not too fast but also not too slow. I legit have almost zero complaints. This video kept me interested for an entire 25 minutes, & that's hard to do on RUclips nowadays. Great job DST!
0:42 *DEEPLY* bothered me that the blast audio was sync'd to the flash. That's not how physics works, and in a documentary style video, you should strive for as much accuracy as possible.
I have seen a number of videos about the March 1, 1954 Castle Bravo Thermonuclear Bomb test and how the yield was far greater than the scientists expected. There is one thing that I am suspicious about. I am suspicious that the published yield of 15 megatons for this test is actually lower than what this test actually produced. There could be an actual higher yield that is classified. This test caused so much trouble for the United States government and bad publicity for this United States government. I can see the government lowering the yield figure to make things look not as bad as they were.
I've wondered the same thing. The Li6H2 vs the Li7H2 makes for an interesting puzzle. No one saw the Li7 stuff doing what it did. My guess would be closer to 20Megatons than 15.
I wonder if any servicemen were vaporized from the Castle Bravo test? I heard the story of the guys in the bunker getting roasted a bit, and saw the pictures of the obliterated camp...
That was 15MT. The Czar Bomba was 57MT but thanks to the Teller Ullman design, it could have been 110MT. It's crazy how scalable H-Bombs are. GIGATON scale devices have been designed but never built. It's what we would need if we were taking on alien invaders because nobody would use a bomb like that here right? RIGHT?!?
Tsar Bomba was dialed down to 50MT and detonated two miles above the ground in order to limit fallout. In fact it was one of the cleanest thermonuclear devices ever tested.
scaling above 100MT isn't very practical, not because of the obscene destructive power, but because most of the energy would be released too high into the atmosphere and wasted
You are right, that's not the correct way to pronounce it. A former President said it that way in the early 2000's and of course it stuck with a lot of people. LOL
@@DSTStudios I've done some more googling based on your hint. Neutron capture. less than 5% comes from the fusion stage. So if its a two stage, fission/fusion device, its all primary. However for a three stage, the first stage is likely to be the same as a two stage, but the final stage will produce a lot of fall out
These tests were surface bursts - all the seawater, coral, sand, rock plus bomb parts become radioactive fallout. A fusion device detonated high enough to not contact the ground is very "clean" since only the fissionable material in the primary and the bomb casing contributes to fallout. Strategically deploying a thermonuclear weapon what is desired is to minimize the radioactive fallout (you do not want the fallout drifting back over your territory or that of a uninvolved country). Also easier to move in and occupy territory that is not contaminated. This is actually why megaton range weapons were phased out and a greater number of smaller, more accurate warheads were phased in. These damn things are really bad for the earth though and it would be preferable if I can keep my 392 cubic inch V8 and we can save the earth by agreeing to not blow each other to hell.
Personally i found the science part of the video interesting the stories about people that were hurt not so much. It is of course a tragedy but with no one to blame for it really except for the government who pays for the damage they caused with our tax money and blames others. But no not the military they were descent folk all things considered, they risked the radiation to help the islanders who did not know what had befallen them. They also didnt know how powerful the bomb would be, nor did the scientists because they overlooked factors that they didnt think of as important. I mean the testing was well unfortunate is maybe the right word, and they did clean up the islands pretty much. Have you heard of the "concrete dome" that is where the topsoil of the islands are today.
This is a complex situation for sure. For the solders I do agree, a nearly all of them were good people and they did the best with what they were given. As for the scientists, it can be very hard putting theory into practice. The aim of this video is not to look down on them but to warn future scientists and engineers about the danger of extrapolation. While I think America could have done better I do not think we were malicious unlike some other world powers, just a bit incompetent.
In the first minute of this video, the sound and light from the explosions reach the observer simultaneously. This is obviously wrong as it would require the speeds of sound and light to be equal. This is reason enough to find another video to watch - such as those that feature the atomic era historian, Richard Rhodes, discussing the era.
I noticed that flaw in the video. The video and sound was edited. Just like a flash of lightning and the thunder comes later because the speed of sound is very slow compared to light. The same thing happened with thermonuclear bomb tests. At first there is an extremely brilliant flash of light and the sound arrives later, the length of the sound delay being proportional to the distance.
This same trick of light and sound is very common in Hollywood movies. Synchronizing sound with the event for dramatic effect. Isn't this why we like movies?
No, it would not self-detonate. The original yield was 100 megatons. It had to be reduced because the airplane that dropped the bomb would not have survived.

Criminally underrated channel
Subbed because I'm happy to find a small channel making good content that isn't just AI garbage.
yet can't correctly pronounce nucleus an nuclear...lolol. "small channel making good content"...lolol.
Same here! So much AI junk being pushed by the YT algorithm.

Fantastic video! Would've never guessed you only had less than 8k subs with the video and production quality being so damn good. Keep it up!
I think this is the most well done documentary about castle bravo i have ever seen. Very good content 👍🏻
Thanks!
This is phenomenal! What an incredible video, please keep up the mahi!

Out of every atomic bomb the U.S. has tested, this would have to be the one that fascinates me the most.

what is the name of the track used at 34:40?

@@chrisroberts7638 57MT. With a non fissile tamper. With a fissile tamper it would have been 110MT. Do some research.
Don’t underestimate the human potential to destroy each other.

Absolutely true
Plus with modern tech you don't need as large of devices, every time you double an ICBM's accuracy you can dock the yield to 1/4th.
Awesome video dude! Terrible pronunciation of “nuclear/nucleus” though lol
Really fantastic!!!

How does fallout increase with a fusion device? The primary is small
The amount of neutrons hitting any solid or liquid matter will turn them into radioactive isotopes

Nice video, but this topic is very large with a simple search on RUclips, or any other platform, so you have a lot of competition.
lol everyone crying about the pronunciation. Who cares...
I hope this doesnt discourage you from doing more on this subject.
It wont

What if the microphones where near the blast zone? Stop bitching you internet neckbeard.

the Tsar had to be reduced because it would self detonate
No, it would not self-detonate. The original yield was 100 megatons. It had to be reduced because the airplane that dropped the bomb would not have survived.
Your silence is wrong
Nu-clee-ar, not nuke-you-lar
Nagasaki was three days after Hiroshima, not two!
Thank you for the correction, I am surprised I missed that one
