Thomas. As the director of the Scientific Advisory Committee, the most important department of the IAEA Secretariat, and the current chief nuclear energy expert in the IAEA, Ray's question is naturally a matter of urgency.

Although the physical properties of this extraterrestrial meteorite are somewhat beyond the imagination of all the people here, the physical properties are physical properties, the kind of magical properties that Tang Feng said, if you can't see it with your own eyes, you just say the sky down, and the stone blooms, and these people here will not believe it.

Tang Feng smiled slightly and said, "Presumably you are Dr. Lei, right?" That's a very good question, and even if you don't ask it, I'll show everyone in this demo the amazing capabilities of this meteorite. ”

After a pause, Tang Feng's gaze turned around on the faces of these people before he said, "Below, is the actual video made by my scientists in one of my bases. First of all, let me declare that this video is real, without any PS, if the big guy doesn't believe it, you can go to verify the authenticity of this video after watching this video. ”

As he spoke, Tang Feng opened another video post, and suddenly, a neat scene of real yàn was displayed on the big screen, but judging from the eye-catching radioactive warning signs printed on the wall and peeled off, this real yàn room was obviously a real nuclear physics room.

In the picture, the meteorite is housed in a glass cover made of special glass, and several personnel wearing white full-body airtight radiation protection suits place a metal box printed with an obvious nuclear radiation warning device on the outside of the glass cover.

Tang Feng pointed to the metal box and said, "This box is made of lead, and inside is polonium-210, a highly radioactive material with deadly properties. Everyone must know what polonium-210 is, right? It's very rare but very radioactive, so for the first test, my scientists chose polonium-210. ”

The camera gives a close-up of the metal box made of lead, and on the outside of the box is a device that is clearly a reading meter, which clearly shows an extremely frightening number, needless to say, indicating the radiation dose of polonium-210 in the metal box.

Wait until the close-up is done. All the scientists retreated, and the next moment, the glass cover slowly rose, and then a close-up of the metal box was given in the frame. Everyone could clearly see that the number on the reading meter, which had been so high, had become zero almost in a matter of seconds

The crowd let out another low shout. Everyone knows that this kind of video is impossible to fake, and Tang Feng has no need to fake it. And when I took the first close-up, all of you knew very well what the number on the reading meter meant. However, the high radiation dose that only needs a few milligrams to kill people is reset to zero in just a few seconds, as if by magic, which means that the polonium-210 in the lead metal box disappeared in just a few seconds, or in other words, polonium-210 completed countless semi-decay in just a few seconds. So much so that polonium-210, which is highly radioactive, decays into a non-radioactive element in just a few seconds.

No one could have imagined why this miraculous situation was happening. In the shot, as the scientists enter the room again, and open the lead metal box, there is only a small pile of powdered metal inside, which is apparently the product of polonium-210's decay. In other words, polonium-210, which was originally highly radioactive in the box, has undergone dozens or even hundreds of decays in just a few seconds, and finally became such a metal powder.

It's simply impossible. It is important to know that the half-life of polonium-210 is as long as 138.4 days. In order for polonium-210 to decay into a non-radioactive element, it takes dozens or even hundreds of decays. Based on 50 decays, it takes at least 138.4*50=6920 days for polonium-210 to decay into a non-radioactive element! Almost 18.9 years!

But that's been nearly 19 years. Isn't it a miracle to be done in just a few seconds?

Seeing that there was a mess below, Tang Feng smiled and explained again: "What does this video mean? I think it's clear to all of you. Again, I repeat that this video is real and valid, and what you see is what really happened. In fact. This meteorite has this magical effect, but this effect can play a more obvious effect in the atmospheric space. ”

"When I discovered this meteorite on the moon, because the surface of the moon is close to a vacuum, the range of this meteorite to perform this function in a vacuum is about 100 meters, and in the vacuum, as long as there is a metal material to block it, then the function of this meteorite cannot be fully exerted. But if the meteorite were in the atmosphere, its coverage would have expanded to a radius of about five kilometers. At that time, I put this meteorite in a box made of outer metal material of the lunar rover, and I made a vacuum glass box from the spacecraft, which successfully brought it back to Earth. However, after arriving on Earth, when this meteorite is out of the vacuum environment, even if it is blocked by metal materials, its coverage will be as high as more than three kilometers. ”

"In fact, the glass cover you see is almost in a pure vacuum state, but once this vacuum state is lifted, then even lead, which can block nuclear radiation, cannot stop this magical function of meteorites within the radius covered by meteorites! So, this first test became the kind of situation that the big guy just saw. ”

"Because of our limited time, I won't show the next video materials to the big guys, but I can assure you that in addition to polonium-210 this time, my scientists have also taken uranium-238 and thorium-232 in spent fuel, unburned and newly formed fissile materials plutonium-239, uranium-235, uranium-233, neptunium, americium, curium and other transuranic elements produced in the irradiation process of nuclear fuel, as well as fissile elements strontium-90, cesium-137, Technetium-99 and other highly radioactive elements have done the same, and the results are all the same. In half a month, my scientists used up almost all the radioactive elements that could appear on the planet, and the result was that in just a few seconds, these radioactive elements became non-radioactive materials! ”

After Tang Feng finished saying this, the entire room had become silent. (To be continued.) )
