Nuclear war in the 19th century After the release of the film, "Apocalypse of the 19th century. A true story of genocide" (https://bit.ly/3fQlShW), there were a lot of questions. Let's start with the first and simplest question. The fact that it was Africa that struck at the modern territories of Siberia and North America. This has been known for a long time, and studies of recent years have only confirmed this version each time, revealing new data, for example, that Africa had Australia as an ally. According to the classification of reserves of uranium deposits by the IAEA, developed in 1988-1989, a special gradation of uranium deposits was adopted. In addition to all other parameters, this gradation takes into account the spectrum and radiation power of uranium ore from each specific deposit. That is, what is important for us to know is that each uranium deposit has its own unique radiation, respectively, the uranium mined from it also has this unique trace. The radioactive footprint for each deposit is as unique as the fingerprint for each person. Here is the "Map of distribution of uranium deposits of the world, from the IAEA Bulletin for 2018" (https://bit.ly/3Cl0yIS): The very first clear fact indicating that it was Africa and Australia that launched a nuclear strike is the presence of traces of African uranium in North America, and in Siberia of African and even Australian uranium. The second fact confirming a nuclear strike from Africa is the so-called "scattering ellipse", directed to the south. What is an ellipse of dispersion is explained in detail in the film "Who Destroyed Tartaria?" (https://bit.ly/3RHNa7j). According to the accuracy and mutual arrangement of the funnels, it is possible to determine the direction from which the charge arrived. In artillery, aviation and missile forces, there is such a thing as a "scattering ellipse", that is, when several charges are launched from one specific point, at one specific target, some of these charges will fall near the target, while the greater the firing range , the greater the deviation. Focusing on the ellipse of dispersion, you can quite accurately determine the direction from which the shot was fired. So, the azimuth of scattering ellipses in Siberia is directed to the south, or more precisely, to Africa and Australia, this is easy to verify by just looking carefully at the map. These two direct facts alone are sufficient to conclude that the nuclear strike was delivered by Africa and Australia. To explain the dating of events, we will use physics and mathematics in relation to round lakes, or rather, to their diameter. All these and many other versions of the formation of round lakes are known to me, and moreover, I do not deny that they are possible. But, about how and in what way round lakes differ from each other, which of them are meteorite and which are karst failures, all this is explained in great detail in the article "Caesium-137 in the Ryazan land" (https://bit.ly/3eledHV). We proceed from the fact that Cesium-137 is a man-made product and is formed only during the nuclear decay of Uranium or Plutonium, therefore the very presence of Cesium-137 is a fact confirming nuclear decay in this place. Given initial data, such as the diameter of the funnel and the amount of Cesium-137 in our time, one can easily calculate the date of a nuclear explosion. We will carry out the calculation using the example of object No. 7, Svyatoye Lake, Ryazan Region. Its diameter is just 357-360 meters. The first thing we need to know is how much Cesium-137 was formed right after this explosion. The total amount of decay products resulting from a nuclear explosion is always directly proportional to the amount of Uranium-235 that has reacted. Compiling the simplest proportion, we get that during the explosion of object No. 7 in the Ryazan region, 39 kg of Uranium-235 entered into the reaction. Therefore, the total mass of the resulting substances should also be 39 kg. To calculate, we translate the mass of the reacted Uranium-235 into the molar amount of the substance: It turns out 165.48 mol. Which gives us 22670.76 grams of Cesium-137 and 15886 grams of Iodine-96, or the same 39 kg of the total mass of the reacted substance. Thus, we learned that in an explosion with a power of 1 Mt, 22670.76 grams of Cesium-137 were formed. According to the results of laboratory studies of soil samples taken at facility No. 7, it is known that in our time the activity of Cesium-137 in the soil of Lake Svyatoye is 3.0 Bq / kg (Becquerel per kilogram), which approximately corresponds to 350 grams of Cesium-137 in calculated on the total weight. The half-life of Cesium-137 is just over 30 years. Every 30 years, the amount of cesium will be halved. Thus, if we count by the number of half-lives in the opposite direction, then for 22670.76 grams of Cesium-137 immediately after the explosion, we get 354.27 grams of Cesium-137 in our time and 6 full half-lives, or 180 years. The allowable calculation error is 10-20 years, in both directions, since for more accurate dating, you need to take more samples from different depths and conduct research with more accurate instruments, however, even such approximate calculations are enough to understand that neither what hundreds and even more thousands of years is out of the question.
