Chapter 24 24. Using iodine 131

On the way, Tokuko asked me as if chatting: "My son, lost 3000, do you feel it?" I didn't understand for a while, so I asked Tokuko: "What does it feel like?" Toko saw that I was concentrating on driving and didn't pay much attention What he said, he said in a different way: "Do you think this game can make a thousand dollars?" I thought for a while and said, "It's difficult. It's too difficult." In my opinion, if you want to make a thousand dollars, you must occupy the right place. And, if this board is where I'm looking, I can get out, and I can put a high-tech set in the room.I have introduced such a product, which can see through and see the front and back of the coin in the cup in advance.But this place is not mine, and I don't have the conditions to do it. If I ask Lao Guan to do it, I'm afraid they won't agree, and they will look down on us.After all, he is a director, and those who gamble are his fellow villagers.

To install the equipment, not only need to connect the line, but also need to replace the cup, but people use very simple cups at home.According to my observation, there are no high-tech things in their bureau, and in 2000, it was difficult to find such things, unlike what you can buy everywhere now. Seeing what I said, Dezi was silent for a while, and said to himself: "That's over, didn't I throw more than 5,000 into the water?" Before I understood, I asked him: "Why did you throw more than 5,000 into the water?" Where did you go?" Dezi said, "The money you took away was not thrown into the water, so where did it go?" I asked Dezi, "Can you give me a thousand wins to get the money and I will take yours?" What does 5,000 yuan matter?" Tokuko said, "How can it be ok? If you can think of a good way to pay thousands, you can get a lot of 5,000 yuan, and my 5,000 yuan will come back. I sell a pack of mushrooms It’s easy for me to carry the bag back from the mountain to dry.” This sounded irritating, and I asked Dezi a little unhappy: “Then you mean to ask me to study whether this game can make thousands of money. Right? It’s not like you said you introduced me to friends, or brought me to see the fun, right?”

Tokuko held out a thumb and said, "The third child is the third child, smart." Damn it, just say what you want, why make such a big detour with me.But I didn't say that. I followed his words and said, "Okay, let me think about it. If you can't figure it out, don't worry about the 5,000. Anyway, you don't want to take the 5,000 back." De The son stared and said, "What do you think I am? You lost 3,000, and I paid for you. The remaining 2,000 is your consolation money. Do you think I am you?" , stingy and paranoid." His words hit my heart.I really don't want to pay him back.Talking, we arrived at the place.Find a hotel near the school.Fortunately, it is a prosperous area with many hotels.But I asked three of them, all of them were fully booked by the parents of the students, and it seems that they are still very popular.

At the fourth house, there is finally a vacant room.Tokuko asked to see the orientation of the room, and asked not to face the street.The room is on the 11th floor. After we saw it, Tokuko was very satisfied, so we went down to the front desk to pay the deposit.When we got into the elevator, there were already several people inside.There are two good-looking girls who seem to be here to travel, a middle-aged woman, a couple who look like a couple, an old man, and a waiter in hotel clothes, who are also pretty. In the elevator, everyone remained silent.Dezi suddenly asked me: "Old man, what kind of stuffing do you have for lunch?" I replied without thinking, "Shredded radish stuffing." I was still thinking: Didn't you eat it too? Why ask me?I really have nothing to say.

Tokuko stopped talking after asking, and looked at me with a very strange expression.I saw that he looked at me very strangely, and didn't think much about it. Suddenly, I found two beautiful girls fanning their hands in front of their noses, as if they were smelled by some smell.The couple also raised their hands and pinched their noses.The old man also looked at me strangely.The middle-aged woman muttered: immoral.If you don't speak anymore, you will be good at fanning.The waiter seemed to be holding his breath.I was wondering, when I suddenly smelled a fart, the smell of shredded radish, that's right.Who farted.

I also subconsciously raised my hand to the nose to pinch it, but looking at everyone, they all looked at me with strange eyes, and then at Tokuko, the expression clearly said: How can you do this?I was so embarrassed.If you want to cover your nose, it doesn't seem appropriate; if you don't cover it, everyone will think it's me who farted.But my heart is like a mirror, I didn't fart.But who would believe it?I could only cover my nose with my hand and act innocent to show that I didn't let it go.Damn Tokuko, actually framed me. As soon as the elevator door opened, everyone ran out of the elevator as if fleeing.I am so depressed.When I was walking towards the front desk, I kicked Tokuko on the buttocks and said, "Why are you so wicked? You made me feel ashamed." Tokuko seemed to be very reasonable: "Why? You took my 5,000 yuan, Is it okay to be a scapegoat? How old do they recognize you when you go out? There is no shame. If you feel that you are at a disadvantage, let’s take the elevator again. You let it go, I will tell everyone that I let it go, you give it I have 5000. What do you think?"

Dezi saw that I didn't agree, so he continued: "I will do it for 1,000 yuan too. Is it okay, the third child?" I was completely speechless. After completing the deposit procedures, Tokuko continued to study the coin guessing game with me, and we did not come up with any results after studying for a long time.I said that I knew some cheaters who played betting and stick guessing all the year round, and I would go to them at night and ask them to see if anyone could have a solution. After I finished my work with Tokuko, I went to find a few stick-guessing cheaters I knew before to learn from them.I went to meet several people, and they all said that it is not easy to guess the heads and tails of coins.No way, hang up the phone one by one and ask.On the phone, I talked about how to guess the coin, to see if they have a good way.Later, a buddy named Haihong said he had a solution.Among the people I know, Haihong is the most educated, with a master's degree.He gambles on betting rounds all the year round, knows where to find all kinds of betting rounds, and often participates in gambling.He is a very calm guy, and also a guy with a typical high IQ, and he will never do anything that is not sure of winning money.Over the years, he won a lot of money in betting games, and used the money to open a car decoration shop.We agreed to talk in his shop the next day.

I went to the store early the next day to find him.When I arrived at his shop, I told him in detail about the game of guessing coins. Haihong was looking for coins everywhere. He found out a dime, played with it in his hand and said, "Third brother, you are talking about guessing heads and tails in this game, so let's pay. There is a door." I asked Haihong: "What door do you have? Tell me quickly." Haihong said mysteriously: "Let's detect it." I was disappointed when I heard it: I use you to detect it?I said: "Haihong, how to detect like a bet? How to detect? They are pros and cons, how to detect?"

Seeing my disappointment, Haihong became more mysterious and said, "Third Brother, you are wrong. The potion you bet on is different from this one." He handed me the dime and said, "Take a look at what material this is?" I took the coin, looked at it, and said, "It's lead." Haihong looked at my serious face, smiled, and said, "Brother San, why are you so uneducated. It's an aluminum alloy." I still Not understanding what Haihong meant, he asked, "What's wrong with the aluminum alloy?" Haihong wanted to explain to me, but felt that explaining to me was futile, so he called his partner and asked her to come to the store.Haihong said he would take me to a university laboratory to do an experiment. An old classmate of his was a chemistry lecturer at the university.

After Haihong’s daughter-in-law came, Haihong lied that I was his client, and the two of us were going to talk about something, so he drove me into a large teacher’s college, and stopped in front of the chemistry department building. down.Haihong told me: "Third brother, my classmate here is a lecturer. I consulted him yesterday, and he said that there is a way to distinguish the front and back of coins that cannot be seen. I made an agreement with him, come with me." I followed Haihong into the office building.Haihong called out a man who didn't look like a university teacher at first sight from the office, and introduced him to me as his college classmate.The two muttered there for a long time, and Haihong's classmate took us out of the office building and into a teaching building.After going up to the fifth floor, he opened the door and entered a laboratory. He gave Haihong and me a pair of shoe covers to put on our shoes.There are all kinds of bottles and jars everywhere in the laboratory, as well as various curved glass tubes, which is very eye-opening for me.

Haihong's classmate told us to sit down.He went to get a metal container and asked me: "This is iodine 131, do you know what it is used for?" Asking me is like asking for nothing, but I still don't want to be looked down upon, so I pretended to understand and replied: "Iodine? Is it flour alkali? We call it a noodle screwdriver. Put a little in the porridge, and it tastes slippery. It seems to be used for steamed buns." Haihong's classmate looked at Haihong after listening, and his expression showed It means: Why did you bring an idiot here. Haihong pretended not to see it, and helped explain: "Iodine 131 is a radioactive substance, produced by nuclear fission, and can emit gamma rays. Gamma rays can treat big neck disease." I seemed to understand, and continued : "Cure big neck disease? Then why do you have to produce fission? Doesn't kelp contain iodine?" Hai Hongna then explained: "That's different. It's iodine 127, which can be eaten. This one can't be eaten. Too much will kill people." I pretended to understand and nodded, but I didn't understand at all.I came here to find out how to guess heads and tails of coins, not to listen to his lectures. That buddy continued to show off and said a set of theories, but I couldn't understand a word.He was still talking for more than 10 minutes, and seeing that he didn't mean to end, I kicked Haihong and quickly stopped him from continuing to talk, and wanted to talk about business.Haihong interrupted his speech at the right time and changed the topic to coins.He put on rubber gloves, sucked a little with a straw with a pouch on the back, then carefully twisted the metal vessel to death, dropped the iodine 131 in the straw on the face of the coin's national emblem, then lit an alcohol stove, and used tweezers Toast lightly with a penny in between.After a few simple strokes, I threw the coin on the table and said, "It's ok." At this time, I didn't understand: What's the use of dripping it? Haihong explained it to me. He said: "Iodine 131 has radiation. Therefore, when the national emblem is facing up, it can be detected. When the national emblem is facing down, it can also be detected." I was puzzled. , I asked Haihong: "Can it be detected? Are you talking nonsense?" Haihong saw that I didn't understand, so he further explained: "There are coins. Coins are made of aluminum, and aluminum absorbs iodine-131. When the national emblem faces up, the radiation value will remain within a normal range. When the national emblem coated with iodine 131 faces down, the material of the coin itself blocks part of it, so the radiation value will drop sharply." Haihong’s classmate listened to Haihong’s explanation with me, and then brought a big suitcase and said, “Come on, let’s do an experiment to detect the radiation intensity.” He opened the suitcase, and there were A screen displayed on the screen.He turned on the switch, picked up a stick-like thing from the side, and approached the coin a little bit, and the numbers on the screen whizzed up.He first leaned the end of the stick against the coin, and let me watch the changes on the screen in the box, then gradually moved away, staying at a position of about one meter, and let me watch the changes in the numbers in the box.The number on the screen was 1780 (metaphorically, I forgot how much it was), and the stick stopped moving.Using tweezers, he turned the coin over with the coat of arms facing down, and showed me the numbers on the screen inside the case.At this time, the number on the screen magically dropped to 180.Turn the coin over again, and the number jumps to 1780 again. He looked at me with my mouth open, very proud, and said, "Now cover it with something, and I'll tell you whether it's head-to-head or tail-to-side." At that time, this picture appeared in my mind: Dezi was playing coin guessing with a stick on it, Haihong was looking at the suitcase in the car below, and Haihong and I communicated with each other through a wireless device.Yes, it can be done.Thinking of this, I asked Haihong's classmate: "Your box is too big. Why do you move it? If you move it over, can your stick be made wireless, or do you need to pull a cable in?" Haihong The classmates looked at me like a fool again. He looked at it for a while, and probably felt that it was impolite to look at people like this, so he went to get a smaller instrument, which was a bit like the things that pass through the security check at the airport now, but slightly smaller.He took the instrument and swiped it at the coin. There was also a small display screen on it, which was as big as the display screen of an electronic watch, and it could also display the radiation value.I wanted to ask him how much this thing cost, but I bought it, but thinking about the way he looked at me, I swallowed the words. Haihong saw that I was holding back my words, so he took the initiative to explain to me: "Third brother, this is for detecting radiation. Generally, the TV we watch has radiation, and this can read the radiation value. Now pregnant women wear radiation protection. Clothes usually claim to be made of nano-silver, but they are actually made of aluminum metal fibers.” I asked Haihong: "Use this to sweep someone else's gambling?" Haihong said: "Third brother, it's not that complicated. I can find materials to make a simple one." Haihong saw that his classmates were still looking at me like that, so he went over to him and said, "Third brother is only in high school, you accept it." Think about your big theories, go and make a simple device for me.” Haihong’s classmate said that he was going to find something in the laboratory downstairs, and asked us to wait in the laboratory. After he went out, Haihong picked up the coin dripped with iodine 131.I was startled and told him to put it down quickly, so as not to be irradiated.Seeing my stupid look, Haihong also smiled and said, "Third Brother, it's all right. After baking, the amount of iodine 131 is very small. It is harmless and even beneficial. It can be used for healing and Prevent thyroid disease." Hey, it's shameful to be uneducated. Haihong continued to explain Iodine 131 to me.He said: "A large amount of exposure will cause death, and a moderate amount of exposure will cause the destruction of the living body and cause disease. Such a small amount is not only harmless, but also has many benefits. It is used in the hospital to treat patients with big neck diseases. .” He told me some things like range, but Nai He didn’t understand a word. After a while, Haihong's classmate came back with a lot of tools.He and Haihong took turns to divide the work. After a while, he made something the size of a mobile phone, installed AA batteries, and put the coins on the table for experimentation.When the coin was turned face down, the device began to vibrate slightly, and when the coin was turned face up, the vibration was significantly strengthened. Seeing that the device was effective, Haihong reinforced all the contacts with solder.During the production, Haihong and I talked about the game of guessing coins to his classmates, and the classmates who wanted to call Haihong also went to share a piece of the action, but Haihong’s classmates said that they didn’t have time and the class was very fast, expressing that they didn’t want to be with him. We go for dividends. I found some dimes from my pocket, and hoped that Haihong's classmates could process more.But he told me: "The life cycle of iodine 131 is 8 days, and the life cycle of baked iodine 131 is 2 days. It is useless for you to process so much." I said, "Then give me some, I'll take it home and process it myself." He hesitated: "This thing is very expensive, and we don't have many laboratories. It's a lot of money for a house." This guy originally wanted money.Just say it if you want money, we are not ignorant people.I directly asked: "I bought it with money, how do you sell it?" The bird man put on airs and said: "This thing is a dangerous substance, and illegal trading will be punished. There are regulations in the "Criminal Law" Yes, I dare not sell it." I thought to myself: Your mother is a big hole.If you don’t dare to sell it and don’t give it back, if you are told to pay dividends and you still don’t go, then why do you keep tossing around for so long? I knew he was asking for the price, so I said, "How many years have I been with Haihong, can you betray you? I will definitely win money with this. If you make an offer, money is not a problem. I am a happy person." He seemed Still very embarrassed, I poked Haihong to make him speak.Haihong also mobilized symbolically and said: "The third brother is not an outsider. I guarantee the third brother that he will never tell." Haihong's classmate gritted his teeth and said, "I and Haihong are in the same dormitory in college. Yes, how many years of relationship, for his sake, okay, I’ll sell you some.” As he spoke, he sucked some with a straw and put it in a small bottle, which was probably filled with the caps of two beer bottles. So much water.He capped the bottle and said: "It's still Haihong's face, I don't want more, you can give 500." I pointed to the small things they made and said, "What about that thing?" Haihong interjected, "You can make anything you want." Seeing what Haihong said, the buddy also became generous: "That thing is for you. I don’t need any money.” I took out 1,000 yuan from my pocket and said, “I’ll buy two copies, and I’ll come back to buy from you when it’s used up.” Haihong’s buddy refused. I really couldn't take it seriously when he refused, so I just saved the money for him, and he happily added some more for me, and then sealed the bottle.Haihong picked up the device and the potion and packed them in a box.I asked for the straw again.In this way, we bid farewell to Haihong's classmates, and we went to meet Tokuko.
