A new word may soon appear in the vocabulary of Japanese tourism workers: "hirashimeity". So a group of researchers led by geologist Mario Vanier dubbed their eerie find - millions of tiny glass spheres, which were carried to the beaches in the vicinity of the city of Hiroshima. These are traces of the first and most terrible use of atomic weapons in the history of combat.
In 2015, Wannier, while studying marine ecosystems, collected sand samples from Motojina Beach near Hiroshima. The scientist's attention was attracted by glass spheres with a diameter of 0.5-1 mm, which resembled museum samples from the places where asteroids fell. According to his calculations, the spheres make up 0, 6-2, 5% of all sand on the beaches within a radius of 11 km from Hiroshima, but there can be at least 3100 tons of them here. And these are only those that lie on the shore.
The idea of the connection of spheres with an atomic explosion immediately received a lot of confirmation. First, they consisted primarily of iron, silicon and calcium. And Hiroshima of those times was inundated with structures made of cheap concrete, stainless steel and marble. Secondly, the Berkeley Laboratory found specific crystals in the microstructure of the samples, which are formed at temperatures from 1800 ° C and above. Thirdly, similar spheres have already been found earlier at the sites of atomic explosions.
“There is a big city, but in a matter of seconds it is gone. The question is: where did the city go, all the material it consisted of? One of the answers is in my hands, ”says Vanier.
The substance evaporated by the force of the explosion scattered around the area, fell to the ground and cooled in the form of tiny spheres. And now these "Hirasimates" can become new artifacts, a reminder for those who do not want to forget the terrible consequences of the atomic bombings.
