A NEW LOOK AT THE H-BOMB HYDROGEN ATOMIC BOMB CIVIL DEFENSE FILM 83312

[@andynon6226]

what a fantastic trove of archive & history you have created, thank you for putting all these awesome old videos "up" (pun intended) Periscope Film for us all to see, i hope you find many more.

0:40 Looks like the attack has started.

[@johnedwards2119]

3:01 "All 'so-called' target areas." WHAT?

[@DS-hy6ld]

Study up, kiddos.... You'll need this info, soon!

[@johnedwards2119]

2:33 "All nu-cu-lar" weapons."

[@manhoot]

I've never been a fan of fallout

[@Johnnycdrums]

There is a lot less fallout/ kt in a hydrogen bomb than in a Atomic bomb.

[@booklover6753]

The opposite is true.

[@Epoch615]

Both kind of right and wrong, while fusion doesn't create fallout, the fusion reaction is triggered through a conventional fission type so it creates just as much fallout as an atomic weapon. However since any detonation is probably going to be a ground burst the yield will matter more than anything else since higher yield means more garbage gets sucked into the fireball and cloud.

depends on the fission fraction of the warhead and its design. There are multistage thermonuclear weapons that use a fission primary (as all thermonuclear weapons do-- a fission weapon that initiates the fusion reaction) and the fusion stage "secondary" which produces the fusion reaction and hugely increases the explosive yield of the weapon. If the secondary is surrounded by a U-238 tamper/casing, which is normally non-fissionable by slow "thermal" neutrons produced by fission, but which CAN fission by the "fast neutrons" produced by the fusion stage of the weapon's secondary fusion stage... this creates a three stage "fission/fusion/fission" weapon which will greatly increase the explosive yield over the primary/secondary yield alone... this tertiary stage can then be surrounded by more fusion fuel which will be ignited by the fission reaction of the third stage, creating a four-stage "fission/fusion/fission/fusion" weapon where the fourth stage greatly increases the explosive yield even more. The Tsar Bomba was a three stage design using a fission primary and a fusion secondary stage. It was originally designed to have a third stage designed for fast fission of depleted uranium, but in the Tsar Bomba test this third stage was omitted. The primary and secondary fusion stage produced a yield of 50 megatons, and because of the tiny fission fraction compared to the fusion component, it was one of the "cleanest" nuclear explosions ever conducted in terms of fallout and radioactive materials produced/released. Had the tertiary fast fission stage been included in the bomb (the U-238 casing) it would have doubled the yield to 100 megatons, but also increased the fission fraction and thus been one of the dirtiest nuclear explosions in history due to the huge amount of energy being released by fast neutron fission. If the bomb were dropped strategically on a target in wartime, presumably for maximum blast yield, it would be detonated high enough in the atmosphere to minimize ground contact of the fireball (several miles high) and thus not generate massively more fallout than the bomb design itself. BUT if the bomb were detonated at GROUND LEVEL, it would vaporize and enormous crater and literally millions of tons of soil, rock, water, etc and all that is sucked up in the cloud and coated with radioactive byproducts of the explosion itself, as well as some being neutron activated and becoming radioactive itself, creating absolutely enormous amounts of fallout. Russia's recent admission of their nuclear drone submarines armed with 100 megaton bombs, essentially nuclear torpedoes, designed to move in close to US shores and then detonate, would create an absolutely enormous amount of fallout, as it would vaporize millions of tons of seawater, sand, and seabed for a mile or more around the explosion point and hundreds of meters deep, excavating an enormous crater and put ALL that material up into the cloud, making it all radioactive.
