Infinite Doomsday Start Draws Luodu Mechanic

A range ability like an aura, with an effect similar to the weakness curse or even the aging curse, but even stronger.

It can not only affect the barbarian Nephalem with enhanced physique, but also affect the quasi-electronic life without entity and almost immune to magic.

And it is most likely not an ability that uses magic.

Well, it seems that it can also slightly affect myself in the armored vehicle a few hundred meters away.

Ruger collected the information in his hands bit by bit, and suddenly saw that the hatch above his head was not closed, so he hurriedly closed it.

However, in just a moment, he felt that the fatigue after being enveloped by the weakness aura had weakened.

After a while, especially after giving himself a dose of treatment needle, he felt that the inexplicable fatigue had been swept away.

"What's going on?"

A flash of inspiration came to his mind, and he seemed to understand something, "Could it be...?"

Mumbling, he exchanged a small box instrument from the store.

As soon as he took it out and opened it, he heard a loud crackling sound, and the pointer of the thing jumped directly to the far right.

Now his face looked even weirder.

He hurriedly adjusted the measuring gear of the instrument to the gear with the highest threshold.

However, after another crackling sound, the pointer of the instrument still jumped to the far right...

"Damn! It's true!"

The results of the two experiments were the same, needless to say, it was this thing!

Ruger was in a bad mood.

"How is it possible? Could it be that just like this underground arsenal in World War II, those ghosts also dug up those things?"

The small box-shaped instrument that Ruger just took out twice is called a Geiger-Müller counter.

It is usually written as a Geiger counter.

It is a transliteration anyway.

This is an instrument that specifically measures the intensity of ionizing radiation.

Ionizing radiation, in simple terms, is radiation that can ionize matter.

As for ionization, according to high school physics, an atom is composed of a positively charged nucleus (composed of positively charged protons and uncharged neutrons) and a number of negatively charged electrons.

When they are combined, the atom appears to be uncharged to the outside world.

When the external input energy is strong enough, it will separate them and turn the uncharged atoms into charged particles.

This process is called ionization, physical ionization.

The energy radiation that can ionize matter is very strong and is very harmful to the human body.

The Geiger counter itself also uses the principle that this radiation can cause matter to ionize for measurement.

It actually measures the number of pulses generated by the gas in the Geiger tube inside the instrument due to ionization caused by ionizing radiation.

So it is called a counter rather than a meter.

This is probably the most widely used and most famous radiation measuring device.

But this thing also has disadvantages.

It is just a counter that records the number of pulses, but it cannot measure the energy level of the pulses, so it cannot distinguish the specific type of radiation.

It cannot tell whether it is alpha rays, beta rays or gamma rays that are at work.

Another disadvantage is that because it is a counter, the frequency of pulses generated by the Geiger tube inside under ionizing radiation has its own upper limit.

Usually if there are 104-105 pulses per second, it cannot measure any higher.

This feeling is a bit like asking a child who can only count to ten to count the number of people in the family.

Under normal circumstances, a family of three or four people, plus grandparents, is only seven or eight people, and the child can count them.

But during the Chinese New Year, the whole family had a New Year's Eve dinner together, and dozens or even hundreds of people returned to their hometown compound. If he was asked to count again, he could only count to the highest number he could recognize, ten.

Ruger measured twice in a row, and the counter pointer turned directly to the far right, which means that the current radiation rate is higher than its measurable upper limit.

It reached its "ten".

The highest value that Ruger's counter could initially measure was more than 10 microsieverts per hour.

Microsievert is the unit of radiation dose suffered by the human body, and its basic unit is sievert, but this unit is too large and there is a big gap with the actual situation, so its small unit is used.

Millisievert and microsievert are commonly used, which are one thousandth and one millionth of a sievert respectively.

This value cannot actually be measured directly by the counter.

The counter actually measures the exposure, and the unit should be roentgen.

The relationship between exposure and dose.

For example, if an assault rifle can fire 200 rounds per minute, then its rate of fire is 200 rounds per minute.

This rate of fire is like the exposure.

If you use this gun to shoot someone for one minute, can you hit that person 200 times?

It seems that it is not impossible.

It seems that it is also possible to shoot him with the muzzle of the gun.

The number of bullets hitting a person is similar to the radiation dose.

The Sievert value on the counter is probably converted from the state of shooting the gun directly at the person.

So in fact, if this person is wearing clothing that can block radiation, he cannot withstand the dose on the counter.

10 microsieverts per hour is not high.

Under normal circumstances, the dose received by each person in China is about 2700 microsieverts per year.

This is because there is also radiation in the natural background.

2700 divided by 365 days and then divided by 24 hours is about 31 microsieverts per hour, which is roughly the natural background radiation.

For an X-ray test, the dose equivalent is about 100 microsieverts.

According to national standards, the annual maximum dose for radiation-related occupational workers is 50 millisieverts, which is 50,000 microsieverts, 0.5 sieverts.

As for the effect of dose on people, it is roughly as follows

0-25 sieverts: no significant damage;

25-50 sieverts: can cause changes in blood, but no serious damage;

50-0 sieverts: changes in blood cells and some damage, but no fatigue;

0-0 sieverts: damage, and may feel general weakness;

0-0 sieverts have damage, general weakness, and the weak may die;

0 sievert 50% fatal injury;

0 sievert or more may die as a result.

Note that the above uses the main unit sievert.

As mentioned before, the upper limit of the earliest measurement of Ruger's counter was 10 microsieverts per hour.

Reaching this value is not to say that it is not dangerous, but it requires long-term accumulation.

To accumulate to the threshold of 25 sieverts without significant harm, it takes "25 times one million divided by 10" hours, that is, 4,000 hours.

Obviously, the harm is not great.

But the gear that Ruger later adjusted to has an upper limit of 1,000 millisieverts per hour, that is, 1 sievert per hour.

Even if there is no feeling of radiation dose at this level, the body will still be damaged after one or two hours of exposure.

However, this is just the beginning.

Ruger's counter does not mean that the current radiation dose is 1 sievert per hour, but at least 1 sievert per hour.

The actual value may be much higher than this.

At this point, Ruger has long understood why he feels tired as soon as he opens the hatch, but does not feel so obvious after closing it.

Obviously, it is the armor of the tank that helps him to resist most of the radiation.

However, even though he was in the tank with the hatch closed, the measured dose was still higher than the upper limit.

This can only mean that the nuclear radiation dose emitted by the metal Tyrannosaurus was already sky-high.

That was already much higher than outside the nuclear power plant, much higher than most areas in the containment of the nuclear power plant, and even higher than the upper limit of the workable part of the workers outside the nuclear reactor.

The power plant in the East Asian island country had a reactor meltdown, causing the dose in the containment to rise to about 4-8 sieverts per hour.

If humans go in without protective equipment, they will die within a few hours.

This level is similar to what Ruger feels like sitting in the tank now.

If you go outside and get closer to the metal Tyrannosaurus, the radiation dose will probably kill a normal person in a few minutes?
