If the information in this VT article (which according to VT is being suppressed) turns out to be correct, then there now exist much more modern and efficient so-called "clean" burning nukes, that do not generate much (or any significant amount of) fallout, upon detonation.
This article about the technical development of nukes was previously located at a different link and has now been moved and possibly, updated:
The History of Nuclear Weapons Design 1945-2015 (Banned by National Security Letter-Ignored by VT)
The average size of a nuclear primary is now down to less than 6 X 12 inches or less with verified yields as low as .05 kilotons. W-48, W-58, B-61 etc. Thatâs equal to about 50 tons of TNT, but large enough to set off a fusion secondary of a much greater size if needed. look it up on Wikipedia if you donât believe me.
Due to the newer inside out boosted gas compression systems coming on line in the 1970âs, a much environmentally cleaner (or greener) burning weapon came into being with fallout issues becoming almost nil. These newer 3rd, 4th, and 5th generation hollow core boasted weapons designs produce very little fallout, if any at all, due to the fusion process consuming almost all of the fissile material during detonation. Low end yields of very high efficiency can be easily created with no minimal critical mass problems to overcome.
In the newest 5th generation devices the uranium or plutonium fissile content has been drastically reduced by as much as 90% only leaving enough fissile material needed to ignite and trigger the internal fission-fusion-fission reaction of the deuterium boost gas. In this process, almost all of the fissile material is totally consumed, producing almost no detectable traces of fallout, as compared to the older designs from the WW2 era.
Due to this advantage in ânuclear stealth technologyâ, almost any large scale explosion greater than 10 tons or more in TNT explosive power can now very easy be passed off as a conventional explosion. Remember, any explosion that leaves a crater greater than 6-feet wide or deep requires a molecular mass explosion of TNT that is greater than 4,000 lbs in weight or two tons of explosives. Most cars, small trucks or jet fighters cannot carry a weapon any larger than this in explosive power.
(The crater left by the Beirut blast is shown on satellite images to be around 140 meters in diameter, or around 459 feet, which is much bigger than 6 feet wide.)
So unless you have a B-52 or a B-1 or a B-2, forget it. It has to be a mini-nuke until proven otherwise. Just because there is no fallout doesnât mean that it wasnât a mini or a micro nuke. Look at the blast photos. A picture is worth a thousand words. Was there a bright instantaneous flash?
Was it a single point or multipoint blast? Was there hydrocarbon residue left behind? Were secondary explosions involved? Was there evidence of very high temperatures and massive thermal damage involved? Was there incinerated or missing bodies involved? Was there an earthquake with a rapid unnatural spike registered on the seismometers?
The list just goes on and on as to what to look for if you know what to look for. Glasstoneâs 1958 book âThe effects of nuclear weaponsâ is a start for those who really want to know, but it is over 55 years old and it has not been updated to cover anything new since solid core weapons designs were invented 70 years ago. There is no new âbibleâ on the newer weapons designs that is still not classified for a reason. They donât want you to really know.
So the âNay-Sayersâ base there arguments on outdated 70 year old information as to how nuclear weapons use to work back in 1945. Well we have come a long way since then baby. Allegedly we even landed on the moon?
The full article is interesting from a technical interest point of view. It explains why the "old" nukes were so dirty (producing fallout) due to having still had very inefficient designs, which appears to make sense. It says that this is no longer the case.
Solid core fission devices are very inefficient due to the fact that about 90% of the fissionable material is only used as a neutron multiplier, and it is only the last 10 to 20% of the outer nuclear core that produced the explosive blast effect.
This is why solid core nuclear weapons are no longer used. They are extremely inefficient. They are very large and bulky in size and they require a sophisticated multipoint, electronically controlled, shape charge, implosion system to function properly and they create large amounts of fallout.
