Chapter 240 Anti-material weapons!
"I call it the romance of nuclear physics." Zhao Zhongyao stepped back a few meters and came to Yu Hua's side, staring at the experimental bench, and said softly.

In the dim laboratory environment, people can clearly see the blue light released by the natural decay of radium in the glass bottle. Showing a unique charm.

At this moment, time seems to stand still.

Yu Hua stood there, staring at the fifty milligrams of radium in the glass bottle, admiring this brand-new element that builds the foundation of the ultimate weapon of human civilization and the foundation of nuclear physics. His eyes are a little blurry:

"It's really romantic."

A deadly and dangerous blue light, a quiet laboratory atmosphere, a dim environment, and streams of high-energy particles invisible to the naked eye.

As Professor Zhao Zhongyao said, radium, which is a radioactive element, creates this dreamy and romantic atmosphere.

However, this romance comes with death.

"In the microscopic world invisible to the naked eye, these radium elements with an atomic weight of 226 are decaying and releasing energy every moment, and the energy is transmitted outward in the form of gamma rays and alpha rays, until it decays into lead with an atomic weight of 82. "

Zhao Zhongyao took advantage of this opportunity to start his lecture: "According to my latest discovery, gamma rays have a very destructive effect on cells and tissues, and are the most destructive of all rays. The electrons in the ions become free states, so that these atoms or molecules ionize, produce energy radiation, and the cells die immediately. Based on this, I think radium, a radioactive element, is particularly toxic, and it is usually forbidden to use hands Contact, keep a safe distance, and use lead as a protective material during transportation."

"For the rest of your life, you must carefully remember what I'm talking about. Nuclear physics research is not only hindered, but also often accompanied by danger. Marie Curie died of leukemia due to long-term exposure to two radioactive substances, radium and polonium."

The toxicity of radioactive elements is extremely terrifying. During the natural decay process of radium, alpha rays and gamma rays containing high energy will be continuously released. These two rays are super toxic to the human body and are more toxic than any A known chemical toxin is hundreds, if not thousands, times more toxic.

After returning to China, Zhao Zhongyao used the 24 milligrams of radium to conduct various nuclear physics experiments, including experiments on the hazards of radioactive elements. A piece of pork was placed next to the radium. After [-] hours, the pork showed obvious burn marks, and the internal muscle tissue All destroyed, like mud.

"Students remember."

Yu Hua has a serious face, and remembers these precious nuclear physics knowledge with heart. Compared with countless people in later generations talking about nuclear discoloration, Zhao Zhongyao's knowledge expounded from an academic perspective is more vivid and vivid.

As for the toxin of radium, Yu Hua, who studied physics in high school, is of course aware of it.

This is the most toxic substance among the known radioactive elements in nature. Only uranium 235 and polonium 210 can surpass radium in toxicity.

"Of course, let's talk about toxicity aside from the dose, the radiation dose of 99 mg of radium will attenuate by 1% at a distance of 10 meters, and the damage to cells is almost minimal. The radiation dose is the strongest at a distance of [-] cm, and the contact time cannot exceed [-] seconds. ." Zhao Zhongyao continued to explain: "If it exceeds ten seconds, the body will be seriously injured, so pay attention to this."

Yu Hua nodded.

"Yu Sheng, do you know what the decay of radioactive elements means?" Zhao Zhongyao looked at Yu Hua and said with a smile.

Yu Hua was stunned for a moment, then shook his head and said, "Students don't know."

"The decay state of radioactive elements releases energy all the time. The energy generated in these atomic nuclei is much higher than the chemical energy generated by molecular chains, about six to seven orders of magnitude higher. The decay process of one kilogram of radium is all The energy released is equivalent to two thousand tons of coal.”

Zhao Zhongyao stared at the fifty milligrams of radium on the test bench, and said softly, "If we can find a way to use the nuclear decay process of a certain radioactive element to generate energy, it will have a huge impact on the entire country and the world, whether it is used as an energy source. In the realm, or as a military weapon, imagine that all the energy contained in one kilogram of radium burst out in an instant, which is approximately equal to 4.2 thousand tons of yellow explosives based on the energy of about 1.3955 megajoules per ton of yellow explosives.”

The difference between atomic energy and chemical energy is millions of times, or even tens of millions of times, and all the top physicists in the field of physics understand the value of the decay energy of these radioactive elements.

"More than 1 tons of TNT..." When Zhao Zhongyao said this, Yu Hua was not surprised. After all, this was an inevitable event in history. However, he was a little surprised. The phenomenon of radioactive elements decaying into energy, thus conceiving nuclear weapons.

A bomb that harnesses nuclear energy, the most powerful ultimate weapon ever built by human civilization.

Professor Zhao Zhongyao realized so early...

"However, at present, the physics community has not found a way to rapidly decay radioactive elements. Such military weapons and energy devices that use nuclear energy still exist and are imaginable. In addition, in addition to this kind of weapons that use atomic energy, you can also By using the energy generated by the annihilation of positive and antimatter as a weapon, this antimatter weapon is more powerful than a nuclear weapon, and according to Mr. Einstein's mass-energy equation, the energy utilization efficiency of an antimatter weapon will reach 100%."

Seemingly feeling Yu Hua's silence, Zhao Zhongyao smiled instead, turned to look at Yu Hua, and said slowly, "Yu Sheng, after listening to this content, have you become more interested in nuclear physics? I generally don't tell you about this knowledge. other students."

Antimatter weapons?
My dear, professor, your academic level has reached such a high level?

Yu Hua was shocked, looking at Zhao Zhongyao's smiling expression, he already felt the other party's intention, his face was serious, and he saluted: "Thank you for your teaching, the students have been taught, and now I really have a very strong interest in nuclear physics. "

I came here for teaching.

A nuclear physics course with almost zero exposure to radioactive elements.

"I can see that you have top talent that is different from ordinary people. Don't waste it. You must challenge complex fields, solve the most difficult problems, and don't let yourself become mediocre." Zhao Zhongyao's face was slightly serious.

Yu Hua was moved by Professor Zhao's good intentions and nodded earnestly.

Zhao Zhongyao smiled and was about to end the course when suddenly, footsteps came from outside the laboratory, and then a figure came to the door of the laboratory.

The person here is Professor Ye Qisun.

"Old Zhao, I've been looking for you for a long time. You are indeed in the laboratory. Someone came to see you." Ye Qisun said after entering the laboratory and seeing Zhao Zhongyao and Yu Hua, with a smile on his face and a sigh of relief.

Zhao Zhongyao wondered: "Is someone looking for me?"

At this time, a tall and straight white man in a suit stepped into the laboratory, with a peaceful face and a smile on his face.

"Zhao, long time no see." Feng Kamen greeted Zhao Zhongyao.

"Professor Carmen?!"
