Mecha Star Wars

Chapter 89 Radiation
When the group arrived at the X-ray room, Dr. Xiao and Xia Jing had already been waiting for a while.The first-aid supplies in the bag are also placed on the table one by one for easy access later.

After Xie Bisheng came, the staff who had been guarding inside withdrew.

"Huh?" Dr. Xiao was stunned for a moment, "He went out, who will control the equipment?"

Dr. Xiao can operate various medical machines, but the equipment in front of him, although it is a magnified X-ray machine, obviously operates differently from medical equipment.

"I'll come." Xie Bisheng said calmly.

It was only then that everyone remembered that Xie Bisheng was originally a scientific researcher.It's just that he's old and doesn't work on the front line anymore.It should be easy for him to operate the machine.

"I proposed to make this machine. I didn't expect it to be used in times other than Pangu." Xie Bisheng also didn't expect that when Yu Guangli reported the situation to him, he was almost lucky to hit the right track.

Machine operation is not complicated for Xie Bisheng, what is complicated is the state of the stars.

Based on its particularity, he expeditiously built an operating room similar to a hospital.

In order to prevent the stars from bursting out of control, the six sides of the shooting room are reinforced with particularly thick steel plates.Such intensity would definitely not be able to stop the stars for long.But because she is not yet stable, there is a time limit for transforming.Xie Bisheng felt that 10 seconds should be able to last.

In order to prevent radiation, the steel plates were covered with thick lead plates, and even the ground was covered with thick barium sulfate concrete, and a layer of tempered bricks was added on top.

The partition between the shooting room and the operating room is also well protected.

The gate is a steel gate sandwiched by lead plates.Thick lead glass was used on the side of the shooting room, and high-strength bulletproof glass was added on the side of the operation room.

Such a room, whether it is explosion-proof or radiation-proof, has achieved the ultimate.

"I suggest letting Lin Fan go in alone, and we all respond outside." Dr. Xiao studied the machines inside while waiting.

"Isn't it okay to eat a little radiation once in a while?" Li Chunhua asked.

"That's an ordinary medical machine. Look at how big it is." Doctor Xiao motioned them to look into the room.

The huge X-ray machine occupies an entire wall of the room, 3.5 meters high and nearly 2 meters wide.The single exposure area is nearly 7 square meters, so the amount of radiation is naturally much stronger than that of ordinary medical equipment.

"Is it okay to wear lead clothes?" Xia Jing asked with a frown.People who accompany the filming or medical staff in the hospital often wear lead clothing to reduce the impact of radiation on themselves.

"No," Dr. Xiao shook his head, "The area of ​​this ray is too large."

"But Lin Fan, doesn't she want to stay inside?" Jin Sichen knew that Lin Fan would be left inside alone to eat the radiation, and couldn't help but worry about her body.

"You may not understand what radiation is all about. Let me explain it to you." Dr. Xiao saw that everyone seemed to know little about radiation, so he had no choice but to take on the role of science popularization.

"There are two types of radiation that we are exposed to every day: one is electromagnetic radiation. It is mainly caused by electromagnetic fields and alternating electromagnetic fields. For example, mobile phone base stations, TV stations, high-voltage lines, mobile phones, computers, microwave ovens, etc. will produce electromagnetic radiation."

"Many people know these things, and even fear them like tigers, but they don't know that ionizing radiation is even more terrifying."

"Ionizing radiation, that is, nuclear radiation. It is mainly caused by high-energy particle rays, such as ultraviolet rays in sunlight, X-rays, gamma rays, beta rays, radiation source rays, etc. The higher the particle vibration frequency, the greater the energy. "

"The next thing to take is X-ray fluoroscopy. This ray itself has no charge, but when it penetrates the human body, it interacts with the substances in the body to produce 'secondary particles'. This 'secondary particle' will make the body Matter is ionized, which produces ionizing radiation."

"The harm of radiation to the human body is not directly caused. It is mainly through the action of ionizing radiation, which destroys human DNA, leads to a decline in immunity, increases the chance of inducing cancer, leukemia and other diseases, and causes fetal malformations."

"According to the latest international standards, the human body can withstand up to 7 Siv of radiation, and every time the body receives 1 Siv of radiation, the carcinogenic rate will increase by 0.0165."

"For example, it takes about 0.5 seconds to take a chest X-ray. In a normal-sized exposure area, the exposure rate of rays is about 0.045 mSv per second. Fertile radiation dose, while increasing the carcinogenic rate by 0.023 times."

"Different body parts have different exposure times because of their internal structure and tissue thickness. The thicker the soft tissue, the longer the exposure time and the different doses of radiation."

"Normally, for one exposure, the abdomen will receive about 0.54 mSv of radiation, the limbs alone will receive 0.01 mSv, the pelvis will receive 0.66 mSv, the lumbar spine will receive 1.4 mSv, and the upper digestive tract will receive 2.55 mSv."

"This is still X-ray radiation. If you do a CT, then its radiation will increase to 8 times. If you only do an inspection occasionally, this level of radiation is not a big deal, but you look at the inside The size of the machine." Dr. Xiao took a breath and continued.

"The harmful effects of radiation depend on the intensity and duration of the exposure. But at the same time, it also has a certain degree of randomness. Some people may not necessarily have problems even if they receive a higher intensity of radiation at a time. This also proves that the human body is sensitive to Radiation has a certain tolerance."

"With the star situation and her size, there is no reference value for the whole body exposure time. We are not even sure whether it can be completed within 10 seconds. But she has at least a metal shell that can block a certain degree of radiation. Although there is It is risky, but it may not cause too many problems. If you go in, what can you use to resist radiation damage?"

Dr. Xiao talked a lot and was exhausted. Xia Jing handed over a bottle of water in time, and Dr. Xiao took a few sips in a row.

"Can't the radiation protection suit work?" Li Chunhua asked hesitantly.

Naturally, there is no shortage of anti-radiation suits in 800 miles. When the giant X-ray machine was used on Pangu before, it was connected to the equipment platform, and then all the staff put on anti-radiation suits to work.

"Radiation protection suits are of course okay, but you are wearing that kind of clothes, and you can't talk and move as freely as you do now. What's the point of going in?" Xie Bisheng replied, taking a serious look at Song Ren.

If you wear protective clothing, it is definitely inconvenient to draw a gun.In case of any accident, it is better to wait outside, after 10 seconds, wait for Xing Chen to transform back into Lin Fan before going in to deal with it.

Song Ren accepted Xie Bisheng's meaning, and lowered his eyes in thought.

"Actually, the distance from the observation window to the inside is not too far. If you want to speak, there is still a microphone to shout, which is much louder than your own voice." Xie Bisheng persuaded again.

Several people looked again, and sure enough, the space in the shooting room is not big, 20 meters square.

The machine fixed the shooting position. If they stood there, the distance between them and the stars was indeed not much different from the previous few times.

Looking at it this way, apart from a wall, it seems that there is not that much difference.

"But what if the shell of the star is not radiation-proof?" Jin Sichen knew that it was useless for him to follow in, and this matter was imperative, but he still wanted to be more sure.

"Ke Wenbin tested the radiation resistance of 818 before." Song Ren replied, "Although the interior cannot be disassembled, 818 can isolate radiation. They speculate that the stars that can absorb 818 should also have radiation resistance."

"It's just speculation, what can it prove?" Jin Sichen frowned even deeper.

If the stars do not have the ability to resist radiation, or the ability to resist radiation is not so high, then the consequences of being exposed to rays for 10 seconds... He dare not imagine.

A group of people frowned, and everyone hesitated more or less in their hearts.

"How about..." Xie Bisheng couldn't see it, and sighed secretly in his heart, wanting to say forget it.

Not only Jin Sichen, several other people in 623 also showed obvious hesitation.

As soon as he opened his mouth, Lin Fan made a sound.

"Okay, don't think so much. Isn't it just for filming? Come on!"

　Here is another knowledge point for everyone, hahaha.I specifically searched for the hazards of radiation on the human body. Oh, I don’t know if I don’t search.But you don't need to panic too much.As mentioned in the text, damage is based on intensity and duration.As long as you don't go to the hospital to take pictures every day, you don't have to worry about using microwave ovens and mobile phones every day.You must know that the sun also has radiation, hahaha.Is this chapter professional enough?vote vote.Comparing
