Anything related to nuclear fusion is very dangerous. This is absolutely true, but it is not as scary as most people imagine. After all, the conditions for achieving nuclear fusion are very demanding. Unlike chemical bombs, the explosive energy of nuclear bombs comes from
Nuclear fusion and nuclear fission are two types of nuclear reactions (the difference between nuclear reactions and chemical reactions is that nuclear reactions occur at the nuclear level and can change the type of elements). Taking the atomic bomb as an example, the nuclear material filled inside the projectile has a purity of 90
Enriching uranium with more than % and causing chain fission of uranium can release huge energy. Nuclear weapons are extremely powerful and can release extremely strong nuclear radiation after explosion. These radiations are released after the fission of a large number of uranium nuclei.
When it comes to radiation, many people think it is scary, but when you have a correct understanding of radiation, you will have a new perspective. Radiation is a phenomenon in which energy diffuses to the outside world in the form of electromagnetic waves or particles. It can be divided into
It is ionizing radiation and non-ionizing radiation. Usually only ionizing radiation can cause greater harm in a short period of time. However, non-ionizing radiation is not that scary. Sunlight is the electromagnetic radiation emitted by the sun. Any temperature at absolute zero (minus 273.15℃
) and above will continue to radiate infrared rays to the outside world. We are exposed to these electromagnetic radiations all the time, but nothing happens.
Uranium (U), atomic number 92, means that there are 92 protons in the nucleus. It has three naturally occurring isotopes in nature (isotopes are elements with the same number of protons and different numbers of neutrons in the nucleus), namely uranium 238 and uranium 235.
, Uranium 234, their abundance in nature is 99.28%, 0.71% and 0.006% respectively. All three are radioactive. Uranium 238 was discovered by Martin Heinrich Klapprot in 1789, and uranium 235
It was discovered in 1935 by Canadian scientist Deng Shida.
Although uranium 238 is highly abundant and can undergo fission, it cannot continue to carry out chain reactions spontaneously, so uranium 238 is also called depleted uranium. However, uranium 235 can, but its abundance in nature is very low, and
They usually coexist with uranium 238, so they need to be separated to purify uranium 235 to a purity of more than 90% before it can be used to make atomic bombs. High-purity uranium 235 can be obtained through gas diffusion methods, gas centrifugation methods, etc.
But the process is not simple. Just to separate 1 kilogram of weapons-grade uranium-235 requires 200 tons of uranium ore.
The nuclear material loaded in the atomic bomb is nuclear weapons grade uranium 235. Uranium 235 is usually used in nuclear fusion power plants, but the purity of that enriched uranium is only about 3%, which is far less pure than nuclear weapons grade enriched uranium.
In many people's minds, radioactive materials are very dangerous, let alone nuclear-grade uranium-235. But researchers dare to hold it with bare hands, not because they are not afraid of death, but because there is really no harm. Radioactive elements will spontaneously emit
Releases nuclear radiation, but when the three natural isotopes of uranium mentioned above decay, they only emit alpha rays, and this radiation cannot even penetrate your skin. The outermost layer of skin on our body is
A layer of dead skin is like a thin layer of armor that radiation cannot penetrate.
In short, direct contact with nuclear-grade uranium with bare hands in a short period of time will not cause any harm to the body. As for natural uranium ore, its radiation dose is even lower. However, it should be noted that although direct contact is not harmful, if uranium
It is still harmful when entering the human body. After all, it still contains radiation and is a heavy metal.
Once uranium is placed in a reactor and reacts, the amount of radiation will be much greater and it is very dangerous. Even if you wear protective clothing, you cannot directly contact it, and you need to use a robot.
The alloy currently in Craven's hands is indeed radioactive, but it is actually not very dangerous.
"Don't worry, buddy, the radiation from this thing is not as strong as a microwave oven!" This is of course nonsense. The radiation from this thing is still quite strong, but it is just harmless for the time being. Wear gloves and don't touch it directly.
Something will happen.
"What's the use of that? You don't want to use this thing to attract those monsters, do you?" Mark felt a little relieved, but still resisted.
In fact, anyone who has received a primary school education knows that it is better to be careful when it comes to things related to "nuclear".
"Of course! Look around here, there are no birds pooping, there is nothing but snow! I believe they must be hungry!" Craven smiled reservedly, not caring at all that one of his companions had just died:
"Believe me, these monsters don't actually feed on flesh and blood creatures...otherwise they would have eaten up the earth tens of millions of years ago!"
Titan creatures are actually omnivorous animals. They can eat anything, but their main food is radiation energy, because the energy conversion rate of other things is too low! If they really hunt, the energy consumed by hunting will be far greater.
It is far less than the energy converted from eating prey.
Every living creature is the most calculated product of nature, and no creature would engage in such a loss-making business.
What you eat is not enough to consume enough energy to chew the food...then why do you still need to eat?
Each Titan is very large. Their huge bodies and various strange abilities require a huge amount of energy. If they only rely on eating to replenish this energy, they will not be able to replenish it even if they stretch themselves to death.
Therefore, Titan's main way of eating is to absorb radiation.
Of course, they sometimes satisfy their appetites, but adult titans rarely have such an opportunity... because they are so big, there are few prey that they can taste when they eat it.
After all, they are so big that most creatures don't need to chew them if they swallow them.
But the young Titan can, like the unlucky King Kong. This guy has never had enough to eat on the island for so many years, so he can only force himself to hunt and eat some fruits...
The same is true for young Scylla. Although the radiation emitted by Scylla can keep them alive, it is too difficult to eat enough. After all, the radiation level is too low these days. Even Scylla is hungry.
In this state, there is naturally no more milk to nourish the cubs.
In ancient times, Scylla would not have cared about his offspring at all. After all, radiation was abundant at that time. After they gave birth, there was no need to care about them. Life can find its own way out.
If you can't find it, you'll starve to death.
It's not like the military hasn't discussed the need to feed these cubs something with high radiation... After all, the disposal of nuclear waste is also a troublesome problem for the United States itself. It's better to feed it to those cubs.
But their plan was soon vetoed by higher-ups... Yes, feeding these guys the nuclear waste would naturally save the government a lot of money... But the question is how to deal with these things when they grow up?
The money spent and lost will be much higher than the waste disposal fee!
Therefore, they decided...it would be best to wait for them to starve to death, but if that was not possible, they could also wait for them to fall asleep.
Anyway don't disturb them.
"Those flesh and blood are just condiments for them, just like you can like to eat sugar, but if you only eat sugar... you will definitely starve to death!" As he said, he patted the lead box: "This thing is
Their staple food!”
"Okay, okay, but here?" Snart accepted Craven's statement, but he looked around... there was a violent snowstorm, and the ground was covered with snow: "This is their home ground, here and
When they fight, our disadvantage is too great."
Craven looked around.
The discovery seemed to be a mistake... This was not his past hunting. Naturally, he could not choose the place where the prey was, and where he was.
Not anymore!
He is a bit limited by his previous experience!
"You are right... let's go down the mountain and fight on the open ground!"
After saying this, Kraven planned to leave with others.
At this time, the sand man spoke: "We're afraid we won't be able to leave!"
The Sandman was very angry. The wizard did have two ends, but the wizard was his! However, Kraven's performance just now made the Sandman feel a sense of contempt... He didn't care about the wizard's death at all!
Of course, the Sandman also knows very well that there is no need for Kraven to care about wizards...he would be happier if he lost a penny!
But the sand man was still angry.
After all, he saw his future from what happened to the wizard. If... he falls into a dangerous situation, the seemingly generous hunter in front of him will never look at him twice because of this, and he will abandon him without hesitation!
No one likes to be treated as something disposable.
The sand people were even less happy.
Of course he wasn't stupid enough to fall out.
"What are you talking about?" Craven immediately looked around cautiously!
"Like you said, those things are very good at hunting...do you think they will let us go?" This time it was Snart, who was still vigilant.
Craven immediately understood what they meant.
It seems that this is really what happened.
"Hahaha... I made a mistake and always looked at these monsters based on my previous experience. My fault!"
Craven stopped smiling. He had been looking forward to this hunt for so long that he even forgot to always be careful!
"Then let's get started!" Craven took a deep breath, immediately put aside all tedious thoughts, and seriously prepared to hunt...or be hunted.
"Mark! Break the blizzard!"
Craven said without hesitation.
"We should have done this a long time ago!" Mark immediately became excited.
As long as he is not allowed to face the real Titan, he will have nothing to fear!
With Mark opening his hands!
Suddenly the blinding snowstorm suddenly stopped!
This has broadened everyone’s horizons!
"I'll fly up to the sky to have a look!" Mark was about to fly up to the sky to check.
But he was immediately stopped by Snart: "Be careful! Don't act rashly. Do you know what is going on with those monsters? You dare to fly into the sky. Are you not afraid of becoming a target?"
Mark froze for a moment.
Indeed, he has even seen the faces of those cubs... How does he know what those monsters look like and what their attack methods are?
If you attack casually, you might not be the first one to be killed.
"Don't be afraid! They can't hide!"
Craven admires people like Snart, who is a good hunter.
After saying that, he opened the lead box.
But nothing happened.
"Hey...are you really lying? You said it so lively...but they are still hiding." Mark waited for a few minutes.
But the other three people were extremely serious.
"Shut up!" Snart said to Mark: "Did you notice it?"
"What?"
"The temperature has dropped!" As he spoke, frost began to form on several people's eyebrows.
Rustling, rustling...
Then bursts of slight sounds came, as if countless insects were crawling!
coming!
Now even Mark knew that the other party was coming!
But immediately, Mark looked stunned.
"Isn't this Scylla's cub?"
It's a group of spiders... very big, but smaller than expected. About the size of a kitten.
Their bodies were all white and their eyes were red. They had been hiding in the snow, and now they crawled out of the snow one after another. They kept opening and closing their breaths and making rustling sounds. Their eight long legs
Walking on the snow, not only did it not make any sound, it didn't even leave any footprints!
Their camouflage is very good and it’s really hard to spot them in the snow if you don’t pay attention.
"This thing...is it really the cub of a Titan?"
"Well, it's indeed a bit small."
If ordinary people saw this thing, they would definitely scream. But who are the people here?
Those are all things I’ve eaten and seen before.
Scylla is the smallest Titan, but he still stands close to a hundred meters tall! These things in front of him...not only don't look like them, they are also pitifully small.
It's indeed a bit unexpected.
Snapped!
There was a gunshot.
It's Mark!
puff!
A little spider was shot and then farted...
"this……"
A few people were still ready to blame Mark, which was too reckless.
But before I could say anything, I saw this scene... Isn't it too bad?
"Then let's just catch one and consider the mission accomplished?"
Mark opened his eyes a little unsatisfied.
"Are they willing to spend 500 million on this thing? Are those rich people crazy?"
On the contrary, Sandman did not take it lightly: "Something's wrong... I know very well what level the wizard is. With the equipment he has, it's absolutely impossible for such a little thing to take care of him silently! There's definitely something wrong!"
In fact, he was right!
With the sound of the gun, the spiders suddenly became violent, and then the dead spider was immediately swarmed by the surrounding spiders. In the blink of an eye, the spiders dispersed, and the dead spider disappeared without a trace.
There is no trace left, even the juice that just burst out from being beaten is completely gone!
At this time, everyone was a little shuddering.
These things actually kill each other!
On the contrary, Kraven is calmer... This is okay. Many insects in nature have this habit, and many insects even start killing each other from the moment they hatch.
"No matter what! Take action quickly, catch one and run away!"
Snart is the most pragmatic, no matter what the mess, just grab one and run away.
