The rays produced by nuclear radiation are high-energy particles.
These high-energy particles hit the semiconductor components, causing changes in component parameters and short-circuiting the equipment.
At the same time, these high-energy particles have a strong penetrating power. Especially the gamma rays inside, with the increase of energy, they can easily penetrate dozens of centimeters of lead plate. In industry, gamma rays are also used for metal detection.
It was more penetrative and destructive than X-rays, which had a wider range of uses.
In order to block the harmful rays in nuclear radiation, the technical team led by Dukui Yangtai adopted a special alloy to shield the rays. This alloy does contain bismuth components.
The Master Craftsman ridiculed the Japanese experts for using bismuth alloys to block the rays, which was very outdated and very degrading.
This sentence made Dukui Yangtai, who presided over the design of the scorpion robot, sneer.
His smile contained a kind of extreme confidence in the professional field and disdain and ridicule for the layman.
"Indeed, there are many metal materials with atomic numbers higher than lead and bismuth."
"For example, the atomic number of uranium is 92."
"Oh, I forgot, uranium has strong radiation, and the core of the fuel rods is uranium metal. With it, the semiconductor electronic equipment will be destroyed faster. "
"It doesn't matter, there are other metals." Dukui Yangtai smiled, "There is also a tritium metal with an atomic number of 93, but I remember that its half-life is only two and a half days. It almost does not exist in nature and can only be synthesized artificially."
"It doesn't matter, it doesn't matter."
"I also know several metals, for example, tritium with a half-life of 20 days. But its atomic number is 99. It's a pity that it also has radioactivity, and the price may be hundreds of millions of US dollars per gram. "
Dukui Yangtai shook his head and thought for a long time, pretending to be suddenly enlightened, and said in surprise, "I also know a metal element with a half-life of 20 years."
"Have you heard of tritium?"
"Last year, Hua Xia's high-energy atomic furnace prepared 2.3 grams of tritium."
"Haha ~"
Dujing Yangtai's three disciples were rocking back and forth with laughter.
Hua Xia prepared 2.3 grams of tritium last year. How could this be measured with money, and how could it be bought with money?
It would take the entire world decades of hard work to come up with a single piece to create a shielding shell.
It was true that bismuth was produced in tens of thousands of tons, but it was already the most suitable metal that could be found under the current technological conditions. This was because its half-life could no longer be measured by numbers. It could exist forever in the world, longer than the universe that had existed for 15 billion years. At the same time, bismuth metal is a metal with almost no radiation, and the bismuth alloy they make is not comparable to ordinary bismuth metal.
Above the metal bismuth, the 93-109 large atomic number metals were all transuranium metal elements.
They had strong radiation characteristics. Among them, only the first four were stored in extremely rare quantities on Earth. The rest all needed to be artificially prepared. A year's production was often calculated in grams.
After that, there would be metals that humans could not even prepare. They would only exist in symbols or in the universe, somewhere in the depths that humans would never be able to reach in their lifetime.
After hearing Dukuang Yangtai's explanation, Zhou Yangwen and the other disciple of Academician Liu were completely dumbfounded. 'The older you are, the more you learn. This Imperial Academician Du Jingyang has probably memorized all the characteristics of the known metal elements in the world.'
At the same time, after what he said, Zhou Yangwen's heart was beating like a drum. Since the metals with higher atomic numbers were either radioactive or did not exist in nature, they were not radioactive.
Then …
What method did Monster Industries use? Zhou Yangwen observed with a diploma and knew that the experimental robot's shell was not lead, nor was it bismuth metal. The color seemed to be a bit like stainless steel, but Zhou Yangwen knew that this was impossible.
"So." Dukuang Yangtai suddenly said: "Mechanical Automation Expert from Monster Industries, please tell me."
"What kind of metal did you use that is more advanced than bismuth metal?"
Facing the proud and confident Dukuang Yangtai, the Master Craftsman did not even bother to explain and directly handed the robot to him. The latter's face was full of disdain. After dozens of seconds, the disdain turned into surprise.
One minute later …
Dukuang Yangtai's eyes were getting bigger and bigger, and his scalp was numb. He knocked on the shell of the product with his fingers no less than fifty times, but every time he knocked, the disbelief in his eyes was magnified.
What was the atomic number of iron?
The atomic number of iron was 26, and there were many branches in the family of iron. For example, steel, such as stainless steel. But no matter what kind, there will be a crisp sound when you knock it with your hand. Some experienced masters can also judge the quality of iron based on the sound.
For example, aluminum with atomic number 13, its sound is more crisp. But if it is replaced with gold with atomic number 79, the sound is very small, even if a gold ring falls on the concrete floor, there is not much echo. As for lead with atomic number 82, the sound is even smaller.
This is the physical characteristic of metal. Usually, the higher the atomic number, the softer the metal. But now the metal shell in front of Dukuang Yangtai completely subverted the previous common sense.
It was hard and felt like steel. However, it was strangely heavy, and strangely, there was no metallic echo. Dukuang Yangtai, who did not believe in evil, even took out a metal key and gently tapped the surface of the metal shell in his hand.
"Dong ~ Dong ~"
The echo was very small, and it seemed that only the metal key was vibrating and making sounds.
Dukuang Yangtai was sure that he had never seen the metal material in front of him. But Dukuang Yangtai was sure that the metal material in front of him had an atomic number higher than bismuth metal.
"This … this is impossible. You can't have the ability to change the atomic number of metal." Dukuang Yangtai was going crazy. He could not recognize the metal in front of him. He was frightened. "If you have this ability, it is equivalent to mastering the great technique of turning stone into gold. Even Einstein can't compare with your achievements … "
"No … impossible …" Dukuang Yangtai was completely bewitched. The other three disciples were also so scared that they could not breathe, as if they were being grabbed by a transformer.
"In … in theory, changing the atomic number requires a huge amount of … of energy. This is impossible."
"Is there something wrong with this little old man's brain?" The Master Metal Expert who handed over the test product spread out his hands to another Master Metal Expert. His expression was both annoying and innocent.
"I think so too." Another Master Metal Expert pursed his lips and said to Dukuang Yangtai, "Don't look at it like a fool. The metal shell in front of you is made of seven special metal alloys. I can tell you that there is no bismuth metal or lead metal among these seven special alloys. "
"I can also tell you that this alloy is not mixed together in proportion, but stacked together layer by layer. If you want to make this alloy, you need to first build a powerful magnetic field generator, and then cast the alloy in a directional magnetic field. "
"Single … single crystal?" Dukuang Yangtai instantly raised his head and lost his voice.
"You guessed it completely. The single crystal of seven different metal elements has the ability to resist radiation, which is equivalent to the ability of 110 atomic number." The Master Craftsman smiled and waved his hand. "How about it? Go back and study with the capable people in your Bachelor's College. See if you can infer our special single crystal technology by using the technology of making fighter jet single crystal blades?"
"Oh, by the way, I Baidu yesterday. You don't seem to be able to make qualified turbofan engine single crystal blades."
"No … impossible, I don't believe it." Dukuang Yangtai muttered to himself.
What was the concept of a single crystal?
A single crystal was a casting material with only one crystal grain. So far, there were many single crystal metals in nature. But every piece of single crystal metal that was discovered broke through the limits of human imagination. They were beautiful, showing the most perfect rhombus proportion or cube.
After unremitting efforts, human beings could finally make single crystal metals.
However, that was only a single metal, or a single crystal blade based on nickel-iron alloy on the most cutting-edge aircraft engine.
What was the concept of seven special alloys? What was the concept of stacked together layer by layer?
Dukuang Yangtai did not know …
