The half-life being shorter means that radioactive decay is more intense. Barium-141 has the most intense decay radiation in the list shown, but it's a threat for less time. This is why you should stay indoors after a nuclear strike for as long as possible: it reduces contact with the short half-life radioisotopes in the environment until several half-lives, meaning that a significant portion of the radioisotopes have decayed away into more stable, less dangerous elements.

And if you are wondering; the lines beside the nuclear explosion is smoke rockets to show the shockwaves.

Science is cool, but dark science is cooler.

This channel is great. To the point, without bullshit. 👍👍

[moonzzzzzz]

this is why Oppenheimer was pretty much a horror movie for me, knowing all of this happened and can happen again with more force is terrifying

Great vid overall. important clarification: the incandescent light from the initial flash is not caused by excited electrons. While all the matter in the initial flash is excited plasma, the heat is caused by the electromagnetic separation of the daughter nuclei being accelerated away from one another at extreme speeds. These nuclei then crash into the surrounding matter and superheat it as well. While the electrons are also at extremely high temperatures and ionized, they have extremely low mass when compared to the nuclei of the matter around them. As such, the majority of the incandescent light radiated in the initial flash is from the super-heated nuclei rather than atomic emission from excited electrons. Also, being incandescent light, the emitted wavelengths cover the entire electromagnetic spectrum, from gamma rays to long-wave infrared and microwaves. However, at first, the most intense radiation is in the shortest end of the spectrum.

nuclear bombs are the coolest thing that I never wanna see used

Can't grasp the full scale of that Activate Windows watermark.

It is not correct to compare the Chernobyl accident to a nuclear explosion. The Chernobyl explosion can be compared to the pulverization of a large amount of long-radiating radioactive material: a so-called dirty bomb. Chernobyl has become an uninhabitable area for millennia, Hiroshima and Nagasaki were rebuilt and have become flourishing cities again.

You can never really grasp the full scale of these explosions from a video.

[glennjpanting]

1:04 - "When a radioactive nuclei is struck with a neutron ...."

2:47 - "The heat from splitting a radioactive nuclei is over 100 million degrees Fahrenheit."

Come on, DS .... the singular of "nuclei" is "nucleus."

I applaud, a simple and informative video how a nuclear bomb works. However there's a mistake, -35F is -37.2C not 1.7C

This short video contains some of the most striking images I've ever seen documenting the explosion process. I suggest the content creator consider re-working the video to break out the process for fission based atomic explosions vs. thermonuclear explosions (two-stage hydrogen weapons utilizing fusion) so the viewer can understand the difference between the two

There are a couple effects that go with the Fireball segment, though they only pertain to the visuals rather than the destructive effects:
1) The double-pulse. It's caused by superheating of air directly surrounding the fireball, which causes it to become opaque. This leads to a short period where the shockwave obscures the light of the fireball before it cools down enough to become transparent again.
2) The rope-trick effect. The "sparks" and "spikes" seen in nuclear blast footage is created by solid matter, whether it be the bomb casing or the tower that the bomb cab sits on (as well as the guy wires stabilizing it). Solid matter transfers heat a lot faster than air and water, which causes said matter to vaporize faster than the shockwave itself.

Regardless of the technical brilliance of such a weapon, nothing good can ever come from such an insidious human creation.

Kudos to the manufacturer of the camera for being able to record and keep the quality of filming even when the paint from the cars is being vaporized by the blast.

Straight to the point, thats the good thing about this channel

Plutonium's half life wasn't a surprise for me, but they 700 Mill from Uranium is insane. It literally cannot fathom that

[IIIAnchani]

as horrific as they are as weapons, they indeed posess a certain beauty...
