stay in the wasteland

Chapter 30 Human Guardian

shoo...

The elevator quickly climbed up, leading vertically to the highest point. Chen Ya also took out the second-hand Geiger counter he bought yesterday, and after pressing the switch, the value was immediately calculated on the miniature blue screen:
[Current radiation value: 315mSv]

Not long after, when the elevator reached the highest point, just as Chen Ya and his friends got out of the elevator, the Geiger counter in his hand began to make a sound.

y... y... y...

In the next second, the radiation value soared rapidly.

【Radiation value: 563mSv】

【Radiation value: 785mSv】

【Radiation value: 906mSv】

……

The Geiger counter jumped several times before it stopped.

"906 mSv."

The corners of Chen Ya's eyes twitched, almost tripled. Fortunately, for the children, as long as the radiation value does not exceed [-] mSv, the body will not be affected much.

To say a few words, the radiation value is the radiation dose per hour.

The maximum radiation that 'ordinary' humans in previous lives could withstand in a year was 1000 millisieverts. Radiation below 100 millisieverts in a short period of time is not harmful to the human body.

That is to say, the radiation dose per hour on the wall is equivalent to the maximum radiation that ordinary people could withstand in a year a hundred years ago.

It's no wonder humans mutate.

But now, mutants' ability to resist nuclear radiation has been greatly improved.

If compared with ordinary people a hundred years ago, the basic data should be:
Ordinary people
Level 100 boundary: [-] mSv
Secondary limit: (year) 1000 mSv
Level 6 death: 6000 sievert, that is, more than [-] mSv, death on the spot.

……

mutant (children)

Level 1000 boundary: [-] mSv
Secondary limit: (hour) 2 Sv, which is 2000 mSv.

Level 15 death: 15000 sievert, that is, more than [-] mSv, death on the spot.

……

Sievert is a large unit, which was introduced in the previous article.

The first-level limit means that the human body will be affected by radiation if the "harm limit" exceeds the value, such as the reduction of white blood cells in the blood. If you stay in this environment for a long time, you will have a higher chance of getting sick.

The second-level limit means that the human body will suffer from radiation sickness if the "tolerance limit" exceeds the value.

The third level of death represents the "lethal dose" of the human body, and it is a one-time death, which is not carried by struggling.

……

As for the types of 'nuclear' radiation, I won't say much here.

There will be a chance to popularize science in the future.

At this moment, Chen Ya and his friends came to the wall, and saw the gray in the distance, as if they had climbed a [-]-meter-high skyscraper, and the pedestrians under the east gate behind them were all the size of ants.

The width of the wall is about 30 meters. The ground is made of concrete and lead sheet materials. The surface is mottled, and there are even some dark blood stains.

Apparently, a lot of fighting took place on the wall.

In addition, in the outer eaves, there are also some heavy artillery, and there are also many sentinel guards.

However, Chen Ya and his four friends walked straight up to a guard and raised their right hands to salute:
"Hello Uncle Guard."

The guard in combat uniform immediately returned a standard military salute.

You are not mistaken!

It was the traditional Chinese military salute in the previous life, and besides feeling kind, Chen Ya also said three words in his heart.

defender

Or, call it a 'human' guardian.

This is a special group, because their predecessors were soldiers from various countries before the catastrophe.

Therefore, the guardians have strict discipline, have firm beliefs, and a tenacious will to fight. No matter how the situation changes, they have always maintained neutrality.

the reason is simple.

Although the nuclear war before the catastrophe was inseparable from the soldiers, the culprit was still the one who gave the orders. After all, it is the duty of the soldiers to obey orders.

Of course!
The real reason is still...

Once a nuclear war breaks out, it is basically difficult to stop unless the earth's environment is greatly changed.

Like the spark that sparked World War II, it was a chain reaction.

You don't fight?
People bombed you with a nuclear bomb, wouldn't you blow it back?

The truth is that simple.

After the catastrophe, in the face of the super-high dose of nuclear radiation on the earth, all countries can only unite to form a community of shared future for mankind. Although the concept of "country" has been cancelled, soldiers still exist and become the guardians of mankind.

Even the human gathering place was established by the guardians.

In fact, the guards were the food and clothing of Chen Ya and others. The orphans in the refuge received free nutrition before the age of eight, but they were all squeezed through the teeth of the guards.

At this moment, the guard said with a friendly smile:
"The radiation on the wall is high, don't play for too long."

"know."

The five of them nodded one after another. Apparently, the guard had long been used to seeing children playing on the wall. He just told them to pay attention to radiation.

The injury limit of adult mutants is much higher than that of children, and they will also wear protective clothing. Although the radiation level on the wall is within the safe range, it is not suitable for long-term stay.

Chen Ya and his friends came to the edge and saw the thick radiation cloud in the distance, so they knew why the radiation value rose rapidly.

Because the radiation cloud contains various radioactive substances, the closer to the radiation cloud, the higher the radiation value.

This is also the reason why Chen Ya speculates that the floating city can shield radiation.

Of course, the huge wall built in the gathering place is not only for isolating radiation, but also for blocking the attack of mutant creatures.

Chen Ya and his friends were lying on the edge of the wall, their eyes wide open, looking at the dim sky outside.

In addition, the ground is very barren, almost no grass grows, and the line of sight can only see about three kilometers at most.

Beyond three kilometers, there is a smog formed by nuclear dust, with almost no visibility.

Seeing a piece of barren ground with occasional swirling yellow sand, Chen Ya couldn't help but say:

"Is this the wasteland?"

At this moment, in the smog three kilometers away, a terrifying roar suddenly sounded.

Roar! ~
Immediately afterwards, a 'strange' mad ghoul appeared from the thick fog.

However, the mad ghoul was red all over, with a lot of cloth wrapped around its back, and its hands were tightly bound. At the same time, there was a pink balloon tied on its left shoulder, and a wooden stick was carried on its right shoulder.

Roar... Roar...

The ferocious ghoul followed the direction pointed by the wooden stick all the way, and came straight to the east wall, which naturally attracted the attention of the guard beside Chen Ya.

In the next second, the guard raised his laser rifle and quickly aimed at the target.

However, after seeing the appearance of the ferocious ghoul through the optical sight, the guard couldn't help being surprised and said:

"balloon?"

Although somewhat puzzled, the guard did not hesitate and immediately pulled the trigger.

Nourish! ~
A ray of orange light shot past.

The speed of light was too fast to describe, and in less than a blink of an eye, that ferocious ghoul was headshot and fell directly to the ground.

At the same time, the guard lowered his gun.

The sharp-eyed Chen Ya immediately felt a little puzzled after seeing this scene.

Under what circumstances, the wild ghoul will release balloons?

Chen Ya was a little confused, but the four friends around him didn't see clearly, they only knew that the guard had killed a mutant creature, so they all showed admiration.

Chen Ya also knew the information about the ghoul, but the ghoul that was killed was obviously different.

This made him feel that it was necessary for him to go and have a look.

Just like that, Chen Ya turned to his four friends and said:

"Shall we go and see that wild ghoul?"

"what?"

The friends are a little timid, but fortunately the guard smiled and said:

"It's okay, I'll keep watch for you from above."

Hearing this, Big Nose and the others felt relieved, and then they walked to the elevator together with Chen Ya, intending to find the ghoul outside the wall and see what was going on.

Before leaving, the five of them also saluted the guards:

"Uncle Guard, let's go and have a look first."

"it is good."

The guard returned the military salute with a smile. In fact, he also wanted to know why the ghoul he killed was dressed so strangely.

It's just that he can't leave his post because he has to perform his duties.

[PS: Stay up late tonight, probably after midnight, there will be an update. 】
