Wallen guessed, "There are no stools in the machine room, you will be tired from standing for so long, and it will be more comfortable to squat." ”

After she finished speaking, the other three laughed, and the laughter made Wallen's heart beat a drum: "What, am I wrong?"

Chen Xinyu smiled: "It seems that you have been away from the profession for too long, and the protection you have learned in textbooks is also blind if you don't apply it in practice." ”

"Could it be that squatting on the root of the wall is also for protection?" Warleen felt as if she understood, but she couldn't say why.

Chen Xinyu explained: "Just now the master and Guo Gong squatted in front of the wall and took off the electron gun, that is to say, there was no X-ray ray when the machine was turned on.

"Although there is no high-energy X-ray radiation, after all, the accelerator has been used for so many years, and some parts may have been polluted by radiation and become radiation sources, which can spontaneously produce rays.

"There is also the fact that some parts will produce some soft rays after high pressure, the energy of soft rays is low, the range is short, as long as it is not within the range of soft rays, it will not cause harm to the human body.

"The reason why the master and Guo Gong chose to squat in the position just now was to try to stay as far away from the accelerator as possible, and then not too far away, otherwise they would not be able to see the magnetron ignition. ”

Speaking of this, Chen Xinyu paused, and then emphasized: "Now the key question is here, why are you squatting?"

"Although soft rays have low energy and short range, they are also X-rays, and when they hit an object, there is a high probability that secondary ionizing radiation will occur, and the rays produced by secondary ionizing radiation can run in any direction without being constrained.

"The secondary radiation rays and the rays produced after radiation pollution, if they run to the human body, will have an impact on the human organs, the reason why squatting is to try to avoid these rays from entering the human gonads, the gonads are irradiated, the light will affect fertility, and the heavy will cause lesions, and the gonads are the most sensitive organs to radiation.

"When people squat, other organs are used as gonadal protectors, so squatting is for protection, shielding and protection.

"Squatting also has a function, that is, it widens the distance between the human body and the accelerator, distance protection.

"The master and Guo Gong withdrew to the labyrinth at the end of the last boot, in order to reduce the time of radiation and time protection.

"Shielding, distance, time, these are the three types of protection against radiation that I told you, and I have also learned it in the textbook, so I will review it for you again this time. ”

Warleen nodded repeatedly: "Oh, I see. ”

Xiao Sun then added: "In this case, it is generally people who have given birth to children who squat in the computer room, in order to protect us young people, such as me and Chen Xinyu, Chen Xinyu just got married, and there are no children yet, and I don't even have a girlfriend yet. ”

"Huh?" Warleen was startled and stammered a little, "Also, is there such a thing?"

Although she is a nuclear major, the teacher has never talked about the knowledge of protection.

"Isn't it?" Xiao Sun's eyes widened, "So I think it's strange, what do you think, a girl comes to do this, once something happens, it's a big deal." For men, the sperm is damaged, and it will be over when it is released, but for women, it is not so simple, the egg is damaged, and the child is broken. ”

"Go, go, why are you so thick-skinned, people are girls, why do you spray all kinds of feces!" Chen Xinyu pulled Xiao Sun aside and comforted Wo Lin, "Don't listen to this kid's nonsense, he just deliberately scared you, any organ is irradiated, there is a dose limit, and if the limit is exceeded, there may be a problem, but it is just possible, not necessarily happening." ”

Seeing that Volin just nodded, her face did not improve, Chen Xinyu comforted Volin: "You have chosen this job, what's the use of being afraid, unless you quit, besides, we are studying this major, we should know how to protect ourselves, right?"

Shi Huijie also comforted Warlene: "Girl, you, you are much stronger than your senior sisters, those senior sisters of yours are in contact with real radiation sources every day, so they should be careful."

"You don't work in a unit of the Ministry of Nuclear Engineering, you don't have to deal with radiation sources, the danger probability that Xiao Sun said can be said to be very small, as long as the accelerator is not high-pressure, there is no radiation.

"The radiation pollution, secondary radiation, soft rays and so on that Chen Xinyu just said are just a possibility, not necessarily generated, after all, our machine is a low-energy machine, and there is not much chance of it happening.

"Besides, if the accelerator has reached the point of squatting in the machine room, it is no longer something you can repair yourself, and we have to repair it for you.

"The reason why we ask the hospital to have someone to repair the accelerator is to prevent the hospital from waiting too long once the machine breaks, after all, this machine is used to treat diseases, which is related to the health of patients.

"For example, if you go to your hospital from here, it will take about 30 hours by train, if the train is delayed, it will take longer, and during the peak passenger period, you can't buy a train ticket, and you have to change trains by plane, you don't have an airport, and you have to change trains, which is also time-consuming.

"There is another situation, if several hospital machines break down at the same time, although you report for repair in time, but we have to repair the machines of several hospitals at the same time, we can't send people to go, this kind of thing has not happened, these times, you have to find a way to make the machine can be used first, and then completely solve the problem when we arrive. ”

Shi Huijie's tone was soothing and eloquent, with a magnetic voice, and Volin's heart was no longer so nervous.

Warlene smiled bitterly: "Construction, can you say that, your job is to carry your body." ”

Shi Huijie smiled: "Whose job is not to carry the body, the type of work is different, the things to carry are different, you work in the hospital, let's talk about doctors and nurses, not to mention anything else, nurses have to use their bodies to carry it after night shifts several times a month, and they are slandered and scolded by patients and families who don't understand them, and they also use their bodies to carry it."

"Doctors should choose whether to treat the patient whether to be palliative or radical, whether to use drugs with few side effects but expensive drugs or drugs with large side effects but cheap, whether to do a high-risk total tumor resection surgery, or temporary partial resection surgery with low risk, and then carry out radiotherapy and chemotherapy for radical treatment. ”

Warleen nodded, silent.

Xiao Hong works in the emergency department, working night shifts eight days a week, and the acne on her face has never broken, and sometimes she will get blood from dealing with the injured in group fights.

Tao Liqiong is such a lively and sweet girl, she was forced to leave her favorite profession and become a family nurse, although it sounds like a family nurse has a high income, but if she is not forced to leave, how could she leave.

Zeng Yiyi, in order to practice surgery, good vegetables and fruits, was badly marked by her, in order to see more different cases, whether she was on duty or not, she stayed in the department, which made Li Lei angry, the two were obviously together, and it was difficult to go on a date.

Zhang Ping ran away pregnant, Warlene told Zhang Ping to slow down, Zhang Ping said as she ran, the patient first, and then consider that the doctor himself was still a pregnant woman.

Every time Han Ting went back to the hospital to see her, he was pulled by their director to do complex surgery, and he stood in the operating room for more than ten hours, in order to avoid delay, he didn't dare to eat food during the operation, he didn't dare to drink water, and he didn't dare to go to the toilet.

Several of them, as well as other responsible nurses and doctors, which are not at the expense of their own bodies.

Thinking of these, a strong sense of longing suddenly surged in Volin's heart, she missed Han Ting, she missed it very much, she missed it very much.

Thinking that Han Ting told her with great interest last night that his deputy senior title had been approved, but she poured cold water on him, and the guilt swelled up.

Wallen took out her mobile phone, walked to an open place outside, and sent a message to Han Ting: I followed the masters to repair the machine outside, and I don't know when it will be repaired.

Last night, in order to tell her the good news, Han Ting kept calling as if he lost his mind, if Han Ting couldn't find her when he called again today, I don't know if he would go crazy.

Perhaps, because of the blow she hit him last night, he was in a bad mood and didn't want to pay attention to her, but she still had to let him know that she missed him.

After waiting for a long time, when Guo Gong and the waiter of the hotel came over with the meal, Han Ting did not reply to the message.

Wallen looked up at the sky and took a deep breath, it was cold, she seemed to smell the snow.

She's been here for almost a month, and she hasn't seen snow yet, so let's go, if it doesn't snow, the temperature is too high, the wheat in the field grows wildly, the nutrients are exhausted, and next year's harvest will be greatly reduced.

Chen Xinyu called Warlene to eat in the operation room, and Warlene answered, bowed her head and wrote a mobile phone message: I'm going to eat, and then continue to repair the machine, the signal in the computer room is not good, I may not receive your information.

The message was sent, and Wallen waited for a while, and Shi Huihui came to call her: "Girl, if you don't eat again, the food will be cold." ”

"It's coming. Warlene glanced at the phone that still hadn't replied, put it in her pocket, and followed Shi Huijie inside.

Xiao Sun grinned with the lunch box: "What's the matter, Wogong, I was really scared by me, and I went to find someone to cry?"

Warlene smiled and shook her head: "I'm not completely ignorant, how can I be so easily frightened, and whispered something to my boyfriend." ”

"Boyfriend, do you have a boyfriend?" Xiao Sun wailed, "How old are you, you have a boyfriend, my God, how can others find a partner as easy as talking, but I, a good young man, am still single, no, I have to change careers!"

Chen Xinyu asked him, "Where are you going to change this time?"

"I'll go to the market instead!" Xiao Sun swore with.

"Yes, you're just so big," Shi Huijie pouted, "Change it back and forth, just go around in our factory, if you have the ability, you can change the name of the unit to tell us, our factory has just a few departments, and you can talk about it all over." ”

Xiao Sun ignored Shi Huijie's ridicule and asked Wo Lin: "Wogong, take the liberty of asking, how old are you?"

"Twenty-eight, what's wrong?" Warleen said deliberately a year older.

"Hehe, hey, hey, my confidence is back," Xiao Sun smiled with a thief's face, "Originally, I thought you were only a little over twenty years old, but now that I know that you are older than me, I am relieved, which means that I don't need to be too anxious to find a partner, I am still young, and I have time and opportunity." ”

Chen Xinyu looked disgusted: "Do you want to make a face, compare your age with other girls, don't say you know me when you go out, I can't afford to lose this person." ”

Laughing, after eating, and then working, Warlene has no practical experience, and it is still others who do it for her, and she follows it.

Before connecting the wire of the electron gun, for the sake of caution, first turn on the high voltage, this time I didn't hear the sound of ignition in the monitor, Xiao Sun then connected the wire of the electron gun, and this time the beam is really out of the beam.

After repeated adjustments, the dose rate returned to normal.

Shi Huijie asked Volin: "Girl, my task is completed, the rest is their business, do you want to stay and watch, or go back with me?"

The dose rate has been adjusted, and the rack, nose, and treatment bed are still unsolved, and everyone else understands the mentality of beginners, and nothing is strange and they don't want to miss anything.

The hospital hopes that the accelerator will be used normally tomorrow, and now that the dose rate problem has been solved, if you work overtime at night, other problems will also be solved before you go to work in the morning.

Therefore, Chen Xinyu and Xiao Sun planned to stay up all night, and Wang Gong took a nap in the operation room, calling him when it was his turn to work, or when he was needed.

As for Guo Gong, every time the manufacturer's engineer comes to repair the machine, he accompanies him, no matter how late, and whether it is a holiday or not, on the one hand, he has to cooperate with the manufacturer's engineer to repair the machine together, and on the other hand, he has to meet the untimely needs of the manufacturer's engineer at any time, such as finding helpers and tools.

Therefore, Guo Gong plans to stay up late together.

Although Chen Xinyu and Xiao Sun both said that they didn't need Guo Gong to accompany them, they were already very familiar with this place, and they could solve what they needed. Guo Gong still insisted on staying.

Wallen was a little embarrassed, she wanted to stay and watch, but it was too late, it was already past eleven o'clock in the evening.

If it was in her own hospital, she would stay up all night, but this is someone else's territory, except for Chen Xinyu, she is not familiar with anyone else, and she is the only girl here, which is somewhat inconvenient.

Seeing that Volin was hesitant, Shi Huijie hurried back, and simply decided for Volin: "If you are itching, stay and go back with them after you are done." ”

Then he explained a few precautions to the others, said goodbye, and drove away.

"Wogong, if you can't hold on, just sleep for a while, you don't have to follow, wait for the accelerator in your hospital to be installed, and I promise to let you stay up all night and have a good time." Xiao Sun was half ridiculous and half caring, and after saying that, he took care of himself and Chen Xinyu and Guo Gong and they went to work.

Everyone in the factory wishes that the hospital engineers can learn the whole technology of repairing the accelerator, so that if the hospital's accelerator is broken, they only need to provide spare parts, and they don't have to run through it themselves.

But Wogong is a girl after all, and she can't be called by a man like Guo Gong.

"Okay, I see," Warleen agreed, cheerfully, "I'm sure I won't be at a loss for myself." ”

In the dead of night, people are sleepy, three people do it, one person watchs, although they are all people who stay up late to repair machines, but occasionally they are still a little confused, four people try to find a topic, laugh and play, so as not to be too quiet and confused.
