We live a few miles north of the only nuclear explosion tests done east of the Mississippi River, the Sterling and Dribble tests at Baxterville, Mississippi. The first was a five kiloton device in 1964. The second a 350 ton device in 1966. The site was a salt dome a half mile underground. Tritium is still being detected in the water runoff from the site today.

[@deserthorsedude]

Salt domes were used because they thought that they would contain the blast and radiation because the domes are large and contained in a rock formation. The other reason was that the technology to find them and drill into them was developed by the oil industry and readably availbe. However without accurate simulation of the geology and nuclear blast effects (a very expensive and 3D calculation) this was only a guess. So they tried it and found leakage that continues to this day, as you described. That's why they moved on to another site. Nevada Test Site. Geology much more stable and without groundwater.

Tritium is one of those things people want because it looks neat when placed in glass and small amounts make luminous watch dials and night sights for firearms, but as an alpha source I wouldn't want to drink it.

[@aloysiusbelisarius9992]

From the historical accounts I've seen, apparently Mandrel-Milrow was a repeat of the Crosstie-Faultless test, which was done in the Hot Creek Valley just east of Tonopah, NV, over a year and half prior. The claim of testing the island as opposed to the nuke itself was actually accurate: Faultless was conducted with hopes of being able to conduct an underground test detonation of the Spartan-ABM warhead, which was designed to yield 5 megatons. The 1-megaton Faultless test was deemed a failure, not because the device itself failed (it was already known to work), but because the surrounding land failed, cracking up, faulting, and collapsing all around ground zero. It became clear that Nevada was not suitable for a test that big, never mind as big as the Spartan warhead. They needed to find another piece of land which could prove to be more structurally sound. Amchitka became their next choice; that island was no stranger to nukes, as they had conducted the Vela-Uniform-Long-Shot test in '65. However, I also read that Nixon had to give direct reassurance to the Alaskan governor that the test would not trigger devastating earthquakes along the coast...understandable since Alaska was still reeling from the (non-nuke-induced) quake that flattened Anchorage in '64. They used basically the same device in Milrow as was used in Faultless, under similar circumstances; and the island remained intact, far more so than Nevada did. Therefore, with the success of that test, the green light was given to use Amchitka as the stage for the Spartan-warhead test, done as Grommet-Cannikin in November 1971.

These were seismic faults. There’s are thousands of them all around the edge of the Pacific where the land meets the sea. You may have heard of the most famous one, the San Andreas fault in California.

[@lukestrawwalker]

Prior to their testing on Amchitka, they were looking for a continental US area to test high megaton weapons underground. The Nevada Test Site was unsuitable due to its proximity to Las Vegas, which was already suffering some effects from even the larger kiloton-range tests they were doing at Nevada Test Site. SO, they chose an area they THOUGHT would be acceptable, near Tonopah, Nevada, about 150 miles roughly north of the Nevada Test Site. They drilled a well and placed a 1 megaton thermonuclear weapon at the bottom, refilled it, and set it off. All their prior ground and seismological studies had said the area would be acceptable, but the test proved otherwise. After the blast, the ground ruptured along natural fissures or ground faults, and the entire valley floor surrounding the test site sank about six feet... forming an escarpment "cliff" where the ground on the bomb-side of the fault dropped six feet and the ground on the other side of the fault line remained where it was. Of course this made the site unsuitable for the planned 5 megaton test of the IIRC Spartan anti-ballistic missile defense nuclear warhead they intended to test. SO, they relocated future tests to Amchitka Island. BUT to make sure that they didn't have a similar screw-up, they decided to detonate another 1 megaton "test shot" under Amchitka to make sure that something similar wouldn't happen as it did at Tonopah... which is what the Melrow event was... to test the island, not the weapon...

Wave action probably existed closer to shore, but nothing serious enough to have long distance effects. This is probably at least in part due to the rather steep gradient, causing the displacement in the water column to quickly move down rather than sideways.

The United States detonated about 1,200 nuclear weapons of varying yields between Trinity and Divider .

Some were air bursts which produce comparatively little fallout and are dispersed by the wind . Then after the atmospheric test ban they were detonated deep underground leaving the area radioactive but sequestered underneath the soil . However that was not all of them and of those the ground bursts are the nasty ones . Fallout would be carried by the jet stream across the country. The Kodak Company was the first group of civilians to notice that something was a foot when the airborne particles were exposing little specks on their film stock. It is hard to find conclusive tests regarding a rise in cancer rates after the start of testing but I have seen a few that claim 10% .

[@borrero-md1196]

Yes and no. As you said, you are no expert and neither I am. But I'm a physician and I like these topics, so I've learned some things. I won't say the effects of nuclear tests from the 50's are not likely to have any effects today. Probably they do impact us one way or another. In terms of radiation though, it's likely that it is no longer a big problem now. As you said yourself, overtime, even the long-lived radioactive isotopes disperse all over the place and even if there's some contaminants around you, the actual amount of radiation they emit is not something the cell repair mechanisms of most living things can't handle rather easily. It's something like what happens in Chernobyl now or where the Iroshima bomb detonated. You might be able to find places with higher than usual radiation levels but that doesn't mean it is inherently hazardous. Just to put things in context, it's known that smokers are exposed to higher levels of radiation, because of radio isotopes contained in some of the stuff used in different steps of tobacco production, than people actually working on Chernobyl today. Also, people who fly frequently are also exposed to high levels of cosmic radiation, way above the leaves you encounter at ground level. So it's all relative. Now, I'm sure a true expert might be able to point out some more lasting effects of these tests that can still be noticeable today. Something tells me though those effects might not even come from the radiation per see, but maybe due to other factors we don't usually think about when talking about nukes.

There's no such thing as a megaton range neutron bomb. The whole point of a neutron bomb is basically to produce a huge burst of energetic neutrons while MINIMIZING the yield of blast and heat. Basically a neutron bomb is a controlled "fizzle". In nuclear parlance, an atomic bomb (or hydrogen bomb primary, the fission bomb that drives the thermonuclear fusion reaction), in order to detonate, has to reach critical mass and sustain it long enough for the chain reaction to take place. The bomb core, of course, whether driven together into a supercritical mass by a gun device or implosion device, wants to disassemble itself to a subcritical mass as soon as possible-- this is one of the keys of constructing a nuclear weapon-- the assembly into a critical or supercritical mass MUST take place fast enough and remain critical mass long enough to sustain the chain reaction. IF the assembly speed is too slow, or the critical mass expands due to heat from the reaction too fast, and turns into a subcritical mass, the actual fission reaction STOPS and the blast and heat yield is greatly reduced, to only a few tons to a few dozen tons of TNT (rather than hundreds or thousands of tons, ie kilotons or megatons respectively). The result is called a nuclear "fizzle"... in a fizzle there is a huge release of neutrons, gamma rays, and X-rays, but not a huge amount of heat or blast effect (blast is created by the sudden heat causing the air to expand explosively). The burst of neutrons is incredibly damaging to living organisms... it can, at sufficient intensity, kill instantly every cell in the body (which normal death does not do) or at ranges sufficient to survive, cause irreparable damage to the organs and cells of the body, leading to death in a few days or weeks. That is why neutron bombs were being promoted by the creator of the neutron bomb, Cohen, for use in a Soviet invasion of Western Europe-- tanks provide excellent shielding for nuclear heat and blast at fairly close range to even mid-high kiloton range nuclear explosions using regular atomic or thermonuclear weapons, and the blast and heat would literally destroy everything and kill uprotected people for MILES around. Due to attenuation by the atmosphere, a neutron bomb's lethal radius is less than a "regular" nuclear weapon, BUT its miniscule (by nuclear standards) blast and heat yield would prevent widespread destruction or collateral damage to nearby homes, farms, towns, and cities and their civilian population. Even heavy tank armor provides NO protection from neutron radiation-- even if the neutrons do not fully penetrate the armor at distance, the neutrons are captured or absorbed or collide with the atoms in the metallic armor, transmuting some of the elements into highly radioactive isotopes, which then decay releasing intense gamma rays, X-rays, and sometimes neutrons, beta, or alpha particles. Basically it turns the tanks in a microwave or X-ray machine that basically irradiates the crew to death anyway. Plus, affected equipment, machinery, and materiel are rendered radioactive for quite some time until the transmuted atoms in their structure undergo radioactive decay into stable isotopes that no longer remain radioactive. The benefit to the local civilian population and friendly troops is, they can be effectively shielded from the neutron burst by just a few feet of earth, which will absorb the neutrons. Of course the ignorant public decried neutron bombs as "killing the people and leaving the buildings intact" which is a ridiculously oversimplified view... the idea that it's a better alternative to using kiloton range nuclear weapons on your own territory to stop a Soviet invasion, and razing your entire homes, farms, towns, and cities to the ground by regular nuclear explosions only a few miles away didn't seem to occur to anyone. Oh well, people are stupid. Later! OL J R :)

[@h-e-acc]

Hmm… something I never noticed before in these nuclear explosion videos. I thought during explosion, the fireball just displaces dust and that’s how we get the mushroom cloud effect. But at closer look, it seems like the fireball actually sucks whatever is around it, that includes dust that then projects upward into the fireball until the fireball dissipates and the dust just circles around . There’s still displacement of dust going on with the blast wave and shock wave. But I thought it’s interesting because blackholes are also known to suck everything around it. And since that nuclear fireball has a tremendous amount of energy, with temperatures inside surpassing the heat of the sun, I’m now starting to wonder whether these fireballs have some properties similar to black holes 😮 well, after all, black holes are just basically collapsed stars. But it’s really interesting 🤔

[@TailRunnerOPSpec]

Nope lol. You can drop a pebble into a dust pit and create a mushroom cloud.

[@xaiano794]

No, but you are right, it exceptionally violently sucks everything upwards. The mechanism is much more simple than people realise. If you look at a normal explosion, even large ones the blast expands outwards at a fixed rate, but watch nuclear fireballs and you'll see they actually slow down as they expand. This is because the nuclear device at the core doesn't 'explode' in the conventional sense, it generates energy, vast, unfathomable energy. The core stops reacting when it is larger than it's original size so for a brief time all the energy of the whole bomb is contained in a device a couple feet across. Obviously this makes it emit light, x-rays in particular, and air is not transparent to x-rays so the air heats up, the air heats to the point at which it's atoms pull apart and form plasma, this plasma is clear to x-rays so it can now heat up the air beyond that to plasma, and so on. The surface area of a sphere is proportional to the radius squared, so you can see why you get a drop off in the growth of the fireball as it expands out. The heating creates a massive pressure wave which precipitates out from the fireball through the air, but remember it's a wave, not an air motion. The motion of the air is upwards due to the buoyancy of the fireball (it's super low density) and a cubic mile of plasma moving rapidly upwards sucks surrounding air in and up with it and carries dust and debris with it. So it's sucking stuff up due to exceptionally low density in the fireball thanks to buoyancy , black holes are high density and pull due to gravity

[@richardclay]

The super hot fireball creates a convection current of immense power...heat rises and the heat from a nuclear explosion rises with a vengeance!

[@NoahSpurrier]

No, it’s just hot air rising that causes the mushroom cloud. The rising bubble of hot air sucks up air and dust underneath and draws it up to form a column. That’s the stalk of the mushroom cloud. All of this rises into the atmosphere where it cools and eventually falls back down as fallout. It’s all heat and air convection currents. Regular explosives and even fires can cause mushroom clouds. Nothing to do with black holes.

[@lukestrawwalker]

Interesting, but the similarity is superficial. When a nuclear weapon detonates, the chain reaction and fusion reaction all take place in a couple millionths of a second. The radiation emitted is SO intense that it heats everything around it, the bomb materials, casing, and the surrounding air, to millions of degrees near the bomb itself. Temperature falls of rapidly with distance, but can still be well over 10,000 degrees directly under the detonation point (ground zero). This rapid release of heat causes the air to expand explosively, causing a strong blast shock wave to form and move outwards as a sphere, until it hits the ground (in the case of an airburst, at which point it bounces off the ground and back up into the fireball. This obliterates anything under the fireball and raises an enormous amount of dust and debris. The fireball itself first forms as a sphere, glowing a brilliant white as the light and energy is radiated away as heat, and because it's SO hot, it expands, meaning that it becomes less dense than the surrounding air. SO, like a bubble of air released at the bottom of a swimming pool filled with much denser water, it begins to rise due to buoyancy effects (convection since it's in the atmosphere, a mixture of gases). The hot, less dense "bubble" begins to rise, so it has to push the air above it out of the way, as it does so it flattens out on top. The outer edges lose heat to radiation and expansion the easiest, so they cool down the fastest, and as they cool become denser. The center of the fireball is the hottest, since it can't radiate away the heat through the already hot surrounding parts of the outer fireball, so it remains the hottest, and therefore lightest, so it begins rising faster than the outer fireball. As it rises out the top of the surrounding fireball, it can then radiate away heat to the much cooler air above much easier, and it pushes against it to push it aside, causing the top of the fireball to remain flattened out somewhat, and the cooling gases from the center are themselves pushed aside by hotter gases coming up from underneath them. This is the beginning of the toroidal rotation "smoke ring" or "mushroom cloud" effect. Now when you have a miles-wide ball of white-hot gas suddenly rising through the atmosphere, it creates a partial vacuum behind it... this causes the underside of the fireball to be sucked up into the center of it, as cooler air rushes in from all sides toward the center to fill this partial vacuum. The sides of the rising fireball itself, which have cooled and gotten somewhat denser and "rolled off to the sides" of the fireball are also sucked back into the bottom of the mushroom cloud, creating a rotating torus (donut-shaped) ring of circulating hot air... the strongest vacuum is in the center of course, furthest from the surrounding outside air, and so it can cause a rising column of hot gas and dust pulled up from the surface directly below the fireball, air heated by the fireball and blast wave itself and thus less dense than the surrounding atmosphere, which then is drawn up into the center of the rising, spinning donut of air (creating the 'stem' of the mushroom cloud). In high megaton atmospheric detonations, the fireball is SO huge and SO hot that it literally burns the air in contact with it, creating a brownish-reddish haze or "shroud" around or on the surface of the fireball-- these are oxides of nitrogen, basically where the air itself has burned and combined part of the 78% nitrogen in the air with the 21% oxygen present in the air to form "smog". This veil of smog can often be seen rolling or sliding off the side of the fireball as it begins to rise in old color footage of the H-bomb tests. As the fireball rises, it often draws warm, humid air up along with the cloud, turning it a brilliant white as it cools sufficiently in the upper atmosphere to form water vapor clouds or even ice crystals. Sometimes the mushroom cloud will push warm, moist layers of air ahead of it as it rises, pushing the warm humid air up into the colder thinner layers of the atmosphere above it, causing a white veil or thin layer of water vapor cloud to form on the top and slide down the sides of the mushroom cloud, or sometimes just push it up ahead of it into the thin atmosphere cold enough to freeze the water vapor into an ice cloud or "ice cap" atop the mushroom cloud. In some of the Operation Dominic high-megaton tests around Christmas Island and Johnston Island in the Pacific, high megaton bombs were dropped over the open ocean and detonated at high altitudes, far above the surface of the ocean... there's footage where you can see a rapidly rising "stem" of water vapor racing upwards, drawn up by the vacuum created under the rising fireball, toward the center of the mushroom cloud... it's offset to one side because it's being carried sideways slightly by the prevailing winds! Eventually the mushroom cloud rises enough that it has cooled to the point it will rise no further, and it spreads out much like a thunderhead does... spreading laterally downwind and as the different layers of the atmosphere are usually blowing in different directions at different speeds, the stem of the mushroom cloud is usually distorted and torn apart as the "cap" of the mushroom cloud flattens out and blows downwind with the wind at altitude. Basically a mushroom cloud is just a really big smoke ring. Same phenomenon, just much bigger. Watch a bubble of air released in a calm swimming pool-- as it rises, it assumes the shape of a nuclear fireball, flattened on top, as it pushes its way up through the denser water, rolling around the sides and turbulent under th bottom as the water rushes back into the space left behind the passing bubble in the water... sometime it will even form a toroidal structure or "air ring bubble" in the water, which expands outwards as it rises, rotating with the center moving upwards and the outsides being passed by the rising bubble and drawn back in toward the center to rise again, just like a fireball turning into a mushroom cloud. ANY explosion, nuclear or not, of sufficient size will create a mushroom cloud-- it's all due to aerodynamics! OL J R :)
