Kodak detected the first atomic bomb before anyone else figured it out. Then they made a deal not to tell anyone. Thanks to HBO Max, and their new show raised by Wolves for sponsoring this video!

A few corrections by an actual nuke. Radium does NOT glow unless there is a massive enough quantity to cause Cerencov radiation (blue light generated when a particle exceeds the speed of light in the medium, in this case, air. an optical shock wave) Even then the glow is faint. Radium dials and watches glowed brightly because the radium is mixed with silver-activated zinc sulfide. ZnS absorbs an alpha particle, is excited to a higher energy state and when it falls back to the ground energy state, it gives off that characteristic green glow. Regarding alleged deaths from I-131 contamination of milk, the 8000 excess deaths were determined by using the long discredited Linear No Threshold (LNT). Here is an analogy I like to use to show how silly this theory is. Suppose I took a bullet and gently tapped you on the chest until I had delivered 1000 ft-lbs. Other than being annoyed, you'd still be perfectly alive and OK. If I delivered that same energy all at once as a rifle shot to the chest, you'd be dead. The LNT says that any amount of radiation, regardless of the speed delivered (dose rate) is harmful. So back to our analogy. Using the LNT theory, after I had tapped your chest enough to deliver 1000 ft-lbs, you'd be dead. Absurd, isn't it. I could find no raw data on the net so I did a few back-of-the-matchbook calculations and using a Gaussian distribution of the dose delivered to the children, I estimate the true death rate to be less than 500, probably less than 200. The panty-wetters will whine that "that's 200 too many". I wonder what the death and disablement statistics were for Polio back then. The model that best fits the evidence is the radiation hormesis theory. This theory states that low level radiation exposure, especially if it is chronic, is actually good for the person. There is a threshold above which the radiation again becomes harmful. Probably the greatest example of this is the famous radioactive high rise apartments in Taiwan. A cancer therapy source had been illegally disposed of in a scrap metal stream. This scrap was melted and extruded into I-beams. Several high rise apartment buildings were built from these I-beams. The radiation dose was very high. It was discovered about 10 years (about 2 half-lives for cobalt-60) later when an occupant took a roll of film to be developed but the radiation had fogged it to black. Google "Taiwan radioactive buildings" for more info. The interesting thing was, when they studied the population, some of which had lived there the entire 10 years, the cancer rates of all types were DRAMATICALLY lower than the general population. The LNT still hangs on simply because so many people are making so much money from it.

The hardest thing for me to wrap my mind around is that the United States has detonated over 1,000 nuclear bombs. I think it's easy to perceive that there have been only a handful, the ones dropped in World War II and a few tests since, but that's far from the truth. Close to 2,000 nuclear bombs have ever been detonated globally that we know of. That's a lot of radiation.

In Under the Cloud the author Richard Miller claims that agencies all over the US were ordered to test for fallout but just about the only place that detected it was Kodak. His conclusion that air currents are so bizarre that the fallout was whisked from out west to Rochester New York without touching down anywhere else. Personally, I suspect the reality was that Kodak couldn't ignore the fallout and the other agencies figured they had better things to do and turned in false reports if any. I figure we all got dusted but Kodak couldn't ignore it since it was ruining their film.

Here's a neat fact ...some older camera lenses, 40s and into 70s I believe, have a thorium coating. Placed on unexposed x-ray film in a dark closet will produce a similar effect. I happen to have one of these old lenses, made in the late 40s. Also, I lived in northern Iowa, Charles City, for a couple of years back around 2000. I found it odd at the number of people 60 and older who had cancer, thyroid problems, and even developmental issues. In a town of

One thing he fails to mention, is that a shorter half-life means a STRONGER radioactive emitter. This is why it is confirmed that Iodine caused throat cancer, and it is assumed that strontium made the same amount of deaths, if not more, when in reality, strontium probably killed less people. It STILL killed people, but to a lesser extent.'s the same reason why thorium will most-likely never make you sick, but plutonium will.

In the mid 60's my family was driving from Los Angeles to Big Bear Lake late at night on a Friday. It was our chance to beat traffic and get some more time in the mountains. I was awake and talking to my dad as he drove. We had reached the summit on highway 38, where it crosses over the range and heads into the valley, when we saw the entire sky light up in the distance. I asked him what that was and he guessed it was an atomic test near Las Vegas. I have not seen another sight like that again. Thank God.

Radium doesn't glow. The particles released by the radioactive decay of radium causes radioluminescence in, you guessed it, radioluminescent compounds known as "phosphors". The best known types are copper-activated zinc sulfide and silver-activated zinc sulfide. Phosphors are often transition-metal compounds or rare-earth compounds of various types. In inorganic phosphors, these inhomogeneities in the crystal structure are created usually by addition of a trace amount of dopants, impurities called activators.

The story: "A nuclear war would wipe out the entire planet!!!" The reality: Since 1945, over 2000 atomic weapons have been detonated around the world and... Meh.
Mark Kennedy
Mark Kennedy Il y a 3 jours
Yes, since 1945, but spread out over 45 years. Explode those 2,000 in an exchange between nuclear powers, over about 1 hour, and you better have a well constructed underground shelter ready, because the fallout from that will reach levels of 10,000 rads in some areas. Even a minute or two would give you a lethal dose at that rate. Which we saw when Chernobyl exploded, and the liquidators were sent to the roof to shovel off the graphite moderator which surrounded the core. They were permitted 30 seconds I believe, or 1 minute maybe, and that was enough to kill a lot of them.

In 1986, there were over 70000 active nuclear warheads. In the event of nuclear war, highly populated areas would be targeted, leading to much more damage, and the bombs would be detonated in a very short amount of time, leading to nuclear winter and mass famine. However, you are most likely right that humanity wouldn't be wiped out, It would just be a very great setback.
