My German Empire

It has been busy to Tianming, and the fire caused by the explosion gradually extinguished. The Governor quickly inspected the gate and found that the four-fan gate of the 745-ton gate was seriously damaged by the shock wave of the explosion, and it is impossible to continue to use.

The helpless governor can only send people to the array of the Canal two, telling them that the Panama Canal is temporarily closed, please bypass. When the fleet is suddenly mourning, there is more than 10,000 kilometers around this, and most ships can not carry so much oil.

The Governor could not control what they do, and quickly returned to the Governor's government to send a telegram. And these fleets have also seen the terrible explosion in the early hours of mind, knowing that it is not intentional to be difficult, nature will not make trouble. Some simply returned to the ground, some of them will take the near port, and the Kung Fu has been scattered.

I sent a telegram, the spirit is relaxed, the governor feels delayed, even a little disgusting.

But he didn't think much, just excessive fatigue, take a break.

When I got home, I slept, I slept until noon, my lady shouted him for lunch, and my face was a little pale governor. "There is no appetite." The voice just fell, he suddenly struggled to climb up, and the

Nuclear radiation causes harm to humans in two ways. One is direct radiation outside the human body, referred to as an outer radiation. The other is that the radiation source is contaminated with air, food and clothing, etc., through breathing, eating and contacting the skin into the interior of the human body, radiates the human body, referred to as an inner photo radiation.

The radiation of the former is equivalent to an external organ gun, and people can at least take appropriate measures to protect radiation, and the latter is equivalent to installing a mechanism in the inside of the human body, only the radiation source is below the security value, or by metabolism Examples outside, otherwise, the agency gun will continue to be launched in the human body.

As for nuclear radiation for the role of the human body, it is necessary to start from the molecular level. The nuclear radiation acts in human cells, and biological macromolecules such as DNA, RNA and proteins can be ionized or excited. This will cause the structural change and activity of macromolecules. On the other hand, nuclear radiation enables ionization or excitation of water in the cell, resulting in loss of macromolecular structures.

In short, radiation will damage biological macromolecules to cause damage or kill cells. In fact, the human body has certain immunity to this damage, which means that healthy people will repair or eliminate these damaged cells. However, such immune compensibility is certain, and these irradiation damage exceeds a certain limit (threshold), which will eventually cause some condition in the human body, and such injury will increase as the irradiation absorption increases.

Mrs. Governor saw a jump, and quickly called a doctor, but he learned that the hospital's doctors and nurses went to the military camp.

"Dear, some are wrong, many people in the military camp have a vomiting diarrhea, and the hospital doctor's nurse has passed."

The governor of the fast-deficient and retreat is sitting on the bathroom floor and muttered. "Is it a collective food poisoning? But I didn't eat anything?"

At this time, don't say that it is an ordinary person, even scientists have insufficient awareness of radiation. After the Second World War II, the Niku and other nuclear powers have repeatedly dispatched nothing of the troops to enter the nuclear explosion area after several nuclear explosions. As a result, many people have had problems in many years.

Even in 1950, the United States launched a terrible children's toys - "Gilbert U-238 Atomic Laboratory".

The slogan of the designer is to let the children "produce stronger desire to scientific".

This kind of toy box appearance is like a holiday spree filled with snacks. There are four items of genuine uranium ore in the box! There is also a gates counter that measures the radioactive substance, which can be used to detect and collect radioactive samples in their own yards. There is also a gamma ray made of γ-rays made of γ-particles and zinc 65 made from the lead 210 and the 210, and the γ-rays made of zinc 65: each of them is simply mounted in a transparent glass cover.

The gift package is lying down is the core component of the toy: the "Wilson Cloud Room" invented by British physicist Charles.

The product's directory is so introduced this high-tech science early education toy: "This set of equipment can absolutely produce a horrified sight! It allows you to see the electronic and α examples along the track at a speed of 10,000 miles per second. Running! Electronics can run a wonderful run trajectory at this speed, you can see the beautiful and intricate run trajectory of the electronic club, and observe the atoms through the cloud room is our ability to contact atoms !!! "

The closed cloud chamber is filled with supersaturated water vapor or alcohol. When the charged particles are interacting with the mixture in the container, the charged particles are injected, and ions are generated in the path, and the ions are condensed into the core. Small droplets, thereby showing the track of the particles, and people can observe the alpha particles of the speed of 1900,000 m / s from this apparatus.

"Users should not take out ore samples from tins because they are easy to peel off and broken. You will brave the risk of radioactive ore in the laboratory." This is a warning attached to the Gilbert U-238 Atomic Laboratory, but the warning Not based on health hazards, but as a poor scientific practice: removed ore from the can to increase background radiation, so that your experimental results are invalid.

Such a high-tech early education toy is not expensive at the time, as long as $ 49.5.

Some people may think that why is such a high-tech high-level product selling so cheap?

The proposed autobiography "People in 1954" live in heaven "said this toy:" This is a multi-educational toy, it is multi experiment and effort by our employees. The results of the work, the government privately supported our toys design, as the government felt that our results can help the public to understand the atomic energy, we have also received the help of the top nuclear physicist in the country, but fortunately Working together in MIT, and our atomic laboratory toys do not have any fakes. All are genuine materials. Of course, the cost is too expensive. We are actually selling, selling a set, but It is undeniable that this Atomic Lab is the most thorough, perfect science toy in history! "

This guy is proud of this is the most common scientific toy in the world.

Of course, if you want to play this high-tech science early education toys, you need to take the risk of radiation .....

At that time, many children had a lot of children to play nosebleeds, dizzy, did not find a phenomenon, so the production is not large, and the Gilbert kit sold is less than 5,000 sets.

From the mid-1950s, scientists have proposed dose restrictions, safety thresholds, etc. In 1956, ICRP (International Radiation Protection Committee) has developed staff and public annual dose limits.

And now no one will think that someone will use radiation as a weapon.
