When they arrived at the X-ray room, Dr. Xiao and Xia Jing had already been waiting. The first aid supplies in their bag were placed on the table for easy access.
After Xie Bisheng arrived, the staff who were originally guarding inside retreated.
"Hmm?" Doctor Xiao was stunned for a moment. "If he goes out, who will operate the equipment?"
Dr. Xiao can operate various medical machines, but the device in front of him, although it is an enlarged X-ray machine, is obviously not operated in the same way as medical equipment.
"I'll do it." Xie Bisheng said calmly.
Everyone then remembered that Xie Bisheng was originally a scientific researcher. He was just old and no longer working on the front lines. Operating the machine should be a piece of cake for him.
"It was I who proposed to make this machine. I didn't expect it could be used for things other than Pangu." Xie Bisheng hadn't expected that when Yu Guangli reported this to him, he felt so relieved that he had gotten something for nothing.
The operation of the machine was not complicated for Xie Bisheng; what was complicated was the state of the stars.
Due to the special nature of the case, he expeditiously built an operating room similar to that of a hospital.
To prevent Xingchen from losing control and erupting, the studio's six sides were reinforced with extra-thick steel plates. This level of strength certainly wouldn't be enough to hold Xingchen back for long. However, since she wasn't yet stable, her transformation had a time limit. Xie Bisheng figured she should be able to hold out for 10 seconds.
To prevent radiation, the steel plates were covered with thick lead plates, and even the ground was covered with thick barium sulfate concrete, and then a layer of tempered bricks was added on top.
The partition between the shooting room and the operation room is also well protected.
The main door is made of steel with lead panels. The filming room side is made of thick lead glass, and the operation room side is made of high-strength bulletproof glass.
Such a room has achieved the ultimate in both explosion-proof and radiation-proof protection.
"I suggest letting Lin Fan go in alone, and we will all provide support outside." Doctor Xiao studied the machines inside while waiting.
"Don't they say it's okay to consume a little radiation occasionally?" Li Chunhua asked.
"That's an ordinary medical machine. Look how big this machine is." Dr. Xiao gestured for them to look into the room.
The massive X-ray machine took up an entire wall of the room, standing 3.5 meters tall and nearly 2 meters wide. A single exposure covered nearly 7 square meters, and the radiation dose was naturally much stronger than that of ordinary medical equipment.
"Wearing a lead vest is not an option?" Xia Jing asked, frowning. Hospital staff and medical personnel often wear lead vests to reduce the effects of radiation.
"No," Doctor Xiao shook his head, "The radiation area is too large."
"But doesn't Lin Fan have to stay in there?" Jin Sichen knew that he would leave Lin Fan alone in there to be exposed to radiation, and couldn't help but worry about her health.
"You may not understand what radiation is. Let me explain it to you." Seeing that everyone seemed to have only a vague understanding of radiation, Dr. Xiao had no choice but to take on the task of popularizing science.
"There are two types of radiation we are exposed to in our daily lives. One is called 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. all generate electromagnetic radiation."
"Many people know this and are even afraid of it, but they don't realize that ionizing radiation is even more terrifying."
"Ionizing radiation, also known as nuclear radiation, is primarily caused by high-energy particle radiation, such as ultraviolet rays in sunlight, X-rays, gamma rays, beta rays, and radiation from radioactive sources. The higher the frequency of particle vibration, the greater the energy."
"What we're going to take next is an X-ray. This radiation itself doesn't carry an electrical charge, but when it penetrates the human body, it interacts with substances inside the body, producing 'secondary particles.' These 'secondary particles' ionize substances inside the body, thus producing ionizing radiation."
"Radiation doesn't harm the human body directly. It primarily damages human DNA through ionizing radiation, leading to a decrease in immunity, a higher risk of cancer, leukemia and other diseases, and can also cause fetal malformations."
"According to the latest international standards, the human body can withstand a maximum of 7 sieverts of radiation. For every sievert of radiation the body receives, the cancer risk increases by 0.0165."
"For example, it takes about 0.5 seconds to take a chest X-ray. In a normally sized exposure area, the radiation exposure rate is about 0.045 millisieverts per second. This means that a chest X-ray will expose you to 0.023 millisieverts of radiation, and the cancer risk will increase by 0.0003795 times."
"The exposure time varies for different parts of the body because of different internal structures and tissue thicknesses. The thicker the soft tissue, the longer the exposure time, and the radiation dose also varies."
"Normally, in one exposure, the abdomen receives about 0.54 millisieverts of radiation, the limbs alone receive 0.01 millisieverts, the pelvis receives 0.66 millisieverts, the lumbar spine receives 1.4 millisieverts, and the upper gastrointestinal tract receives 2.55 millisieverts."
"This is still the radiation from X-rays. If it's a CT scan, the radiation level will increase to 8 times. If you only have a check-up occasionally, this level of radiation is not a big deal, but look at the size of the machine inside." Dr. Xiao took a breath and continued.
"The harmful effects of radiation depend on the intensity and duration of exposure. However, there is also a certain degree of randomness. Some people may not experience any problems even if they receive a single high-intensity dose of radiation. This also proves that the human body has a certain tolerance to radiation."
"Given Xingchen's condition and her size, there's no reference value for the duration of full-body exposure. We're not even sure it can be completed within 10 seconds. But at least she has a metal shell that can block a certain degree of radiation. While there are risks, it's not likely to be a major problem. What can you do to protect yourself from the radiation when you go in?"
Doctor Xiao spoke a lot and was exhausted. Xia Jing handed him a bottle of water in time, and Doctor Xiao drank several gulps.
"Isn't anti-radiation clothing enough?" Li Chunhua asked hesitantly.
There is naturally no shortage of anti-radiation suits in 800 Li. When the giant X-ray machine was used on Pangu before, it was connected to the equipment platform, and all the staff wore anti-radiation suits to work.
"Of course you can wear anti-radiation clothing, but if you wear that kind of clothing, you won't be able to speak or move as freely as you do now. What's the point of going in?" Xie Bisheng replied, looking at Song Ren intently.
If he wore protective gear, it would be inconvenient to draw his gun. If something unexpected happened, it would be better to wait outside for 10 seconds until Xingchen transformed back into Lin Fan before going in to deal with it.
Song Ren understood Xie Bisheng's meaning and lowered his eyes in thought.
"Actually, the distance from the observation window to the inside is not far. If you want to talk, there is a microphone and you can shout much louder than if you shout yourself." Xie Bisheng advised again.
After a few people took another look, they found that the space in the studio was not big, only 20 meters square.
The camera fixed the shooting position, and if they stood there, the distance between them and the stars was indeed not much different from the previous times.
Looking at it this way, apart from the presence of a wall, there doesn't seem to be that much difference.
"But what if the outer shell of the star is not radiation proof?" Jin Sichen knew that it was useless for him to follow in. This matter was imperative, but he still wanted to be more certain.
"Ke Wenbin has previously tested 818's radiation resistance," Song Ren replied. "Although the interior cannot be disassembled, 818 can block radiation. They speculate that being able to absorb the stars in 818 should also have radiation resistance."
"It's just speculation, what can it prove?" Jin Sichen frowned even deeper.
What if the star is not radiation-resistant, or its radiation resistance is not that high? Then the consequences of being exposed to radiation for 10 seconds inside... He couldn't imagine it.
A group of people frowned, and everyone was more or less hesitant.
"Or..." Xie Bisheng sighed inwardly when he saw that it was not possible and wanted to give up.
Not only Jin Sichen, but several other members of 623 also showed obvious hesitation.
As soon as he opened his mouth, Lin Fan spoke up.
"Okay, stop thinking about it. It's just a film shoot, right? Come on!"
Here is another piece of knowledge for everyone, hahaha. I specifically searched for the harm of radiation to the human body. Oh, I didn’t know it if I didn’t search. But there is no need to panic too much. As the article said, the damage is based on the intensity and duration. As long as you don’t go to the hospital for X-rays every day, you don’t have to worry about using microwave ovens and mobile phones in daily life. You should know that the sun also has radiation, hahaha. Is this chapter professional enough? Vote for it. Love you
