Chapter 55, Cobalt 60

Liu Yan can read minds, who will believe it when he talks about it like this?

"I can't prove it, but they're absolutely lying. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ”

Hearing this, Tang Wanyun directly pulled out his gun: "Let me tell you, if the box is really taken by you, then your life will really be over, now tell me where the box is, maybe it can be remedied, where is the box?" ”

Although Liu Yan hadn't seen Tang Wanyun a few times, he knew Tang Wanyun's temper, and he wouldn't be so angry until he had to, and now Tang Wanyun's temper was so irritable that it could only show one problem: it was important to lose the contents of the box.

However, as far as Tang Wanyun's intimidation method is concerned, even if they bring a box, they will not recognize it.

After receiving Qin Yuer's call, Qiu Zhongtian hurriedly asked the driver to drive, and rushed to this side in a hurry.

The driver drove very fast, and it didn't take half an hour to arrive.

As soon as he got out of the car, Qiu Zhongtian hurriedly ran in front of a few people, and after looking at it carefully, he said to Tang Wanyun: "Director Tang, it's just a few of them, it's these boys who snatched my box." ”

Along with Qiu Zhongtian, there was also a young man with strange detection equipment, he took the instrument, probed around the tattooed men, and then said to Qiu Zhongtian: "Dean Qiu, there is no radiation source on them, and the box should not have been opened." ”

Tang Wanyun was relieved when he was confirmed, he sent all the police forces of Yunling that night, just to find this box, and now he has found the person who grabbed the box, and the whereabouts of the box will be known.

"Tell me, where's the box? Have you ever opened it? ”

He was very anxious, if he couldn't find the box within forty-eight hours, the consequences would not be something he could bear, Qiu Zhongtian, the dean, would not be able to finish the game, and he would not be able to do it as the director, after all, this was something that happened in his own jurisdiction, and if he was investigated, he would be the first to be unlucky.

The tattooed men had already decided that they would not admit it no matter what, and they would not speak in the face of Tang Wanyun's interrogation.

"Director Tang, it's not a way to go on like this, thirty hours have passed, and there are still eighteen hours, if these boys don't say it, there will be a big incident at that time."

How could Tang Wanyun not know how powerful this is? He had already done everything he could, and he was almost on the top ten tortures of the Manchu Qing Dynasty, and several people still beat them to death and did not admit it, looking like a dead pig was not afraid of boiling water.

"There's no evidence, you're coming to bite me!"

Tang Wanyun really had no choice, and when he saw Liu Yan and Chen Xiaodrunk standing behind, he hurriedly greeted him: "Xiaoyan, I know that you have the means to make these boys speak, for the sake of Xiaoyu's face, help Uncle Tang." ”

Qiu Zhongtian didn't know Liu Yan, but when he saw that Tang Wanyun, the director, begged him, he thought that this young man should have this ability, so he also got up: "Yes, young man, if you can't find the box for another eighteen hours, something really will happen, our status is not important, what matters is human life." ”

Liu Yan was confused when he heard it: "No, you are talking like the doomsday crisis, I can't understand it myself, how can I help you?" At least you'll have to let me know what's in this box, right? ”

Qiu Zhongtian was stunned: "I'm in a hurry, I forgot about this stubble, there is medical cobalt 60 in this box, which has just left the factory of China National Nuclear Corporation, and it is a radiation source with extremely strong radiation." ”

As soon as he heard this, the people present were shocked, Liu Yan was also black-headed, as a representative of the high school chemistry class, he was no stranger to Cobalt 60.

Cobalt-60 is a β-decay nuclide that emits β- and γ rays, with β-rays having a maximum energy of 0.315 megaelectron volts and γ rays having two energies of 1.173210 and 1.332470 megaelectron volts. The half-life is 5.272 years. 3.7x10 □ cobalt 60 kg 8.85x10_□ mg. The 3.7x10□ Becker cobalt-60 point source irradiated 13.2 roentgens/hour at a distance of 1 cm. Cobalt-60 is a highly toxic nuclide, which has an effect on the whole body, with an effective half-reduction period of 9.5 days and a maximum allowable stock of 3.7x10□ becqueel in the human body. The maximum allowable concentrations of cobalt-60 in the air of radioactive workplaces and in open water sources are 0.33 and 370 Bq/L, respectively, and are chemically identical to the element cobalt.

Cobalt-60 is most commonly used in industry and medicine, and because of its strong radiation, it is very particular about transportation.

"Dean Qiu, shouldn't the transportation of cobalt-60 be fixed on a truck with a large cobalt bag made of lead to be transported safely, and the country has strict requirements for transporting radioactive sources, so how can it be solved in one box? Still walking down the street? ”

Qiu Zhongtian's old face flushed: "This box is the latest development of the nuclear power, specially used to facilitate the transportation of cobalt elements, there is a national patent certificate, the box has a device to detect leakage, and the car we took is also a special vehicle for the transportation of radioactive sources, but yesterday the road leading to our hospital was overhauled, the car could not enter, and the equipment of the hospital was waiting to be installed, I was in a hurry, so I walked in with cobalt 60, which Cheng thought that someone actually robbed in broad daylight." ”

"I don't see any news yet, so the loss of cobalt-60 hasn't gotten out yet?" Liu Yan continued.

Tang Wanyun nodded: "I followed up and reported this, and the mayor said that he would report it if he couldn't find cobalt 60 in forty-eight hours, so as to avoid causing unnecessary panic." ”

When Liu Yan heard this, he felt very inappropriate: "Forty-eight hours later, everyone is dead, and I still report a fart." ”

Cobalt-60? It seems that these boys have really not opened the box, otherwise with the high-intensity radiation of cobalt 60, I am afraid that a few people would not have survived.

"Dean Qiu, why didn't you find the box in forty-eight hours? According to you, as long as this box is not opened, there is no radiation risk from Cobalt-60. ”

The young man who came with Dean Qiu explained: "Although this lead box has greatly improved the efficiency of transportation, it also has its own shortcomings, that is, the ability to resist radiation has a time limit, after many experiments, with the penetration ability of cobalt 60, after 48 hours, the lead box is in danger of being penetrated, and cobalt 60 will no longer be safe, so this lead box is only used in the case of traffic congestion in a short distance, but now this lead box has been robbed, if it exceeds 48 hours, Those who come into contact with the box will be exposed to high-intensity radiation. ”

Liu Yan only felt that this kind of box containing cobalt 60 was too risky, although it could be easily transported, but if something unexpected happened, such as now, it would be very tricky.

Liu Yan knew the seriousness of the matter, and came to the tattooed man and squatted down: "Dude, did you hear what we said just now?" What kind of treasure do you think you're robbing? Actually, it's a Pandora's box, tell me where this box is, it's not that bad. ”

The tattooed man turned his head to the side: "I said we didn't rob it, how do I know where it is?" ”

It seems that without some means today, this group of guys will not be honest, although his own can explore their brains, but he can't be accurate enough to find something in his brain.

He took the silver needle out of his bosom again: "Do you know how much pain it will cause to stick this silver needle between your fingernails?" You will feel that life is worse than death, and it can only be regarded as a slight injury in terms of medical evaluation, Director Tang is a police officer who wants to beat you up but the discipline does not allow it, but I am not a policeman, I can make you worse than death in front of them, believe it or not? Say it, everyone is doing well, where's the box? ”

The tattooed man still didn't speak, but the man next to him faltered a little.

"Brother, don't hit me, I've said everything."

The tattooed man glanced at him in surprise: "I'm grass, second child, didn't you say yes and don't say it, you dare to fucking fight back?" ”

The second child cried with a sad face: "Boss, this is going to die, don't you want to say it?" ”

Liu Yan said with a smile: "Boss, if you don't say it, it's because robbery is a big crime, you don't dare to admit it, but the legal net is restored and there is no leakage, and these things you commit will be found out sooner or later, at that time, it is estimated that several lives will be added, you will not calculate, if you find it now, you don't have to make a fuss, you will go to prison for a few years at most, if you make a fuss, I'm afraid you won't be in prison, I said that you are also not a big boss, why can't you calculate such a simple account?" ”

The tattooed man was finally moved: "We robbed the box, but we really didn't know that there was such a powerful thing in it, I saw him carrying the box one day, thinking that there was money in it, but it turned out to be three shiny gadgets, and we didn't know what it was, so we hid it in the old flue-cured tobacco room in the Yunling tobacco area?" Prepare to take a shot on the black market after the rumors have passed. ”

Liu Yan heard it: "Three shiny things, have you opened the box?" ”

The tattooed man nodded and continued: "We took a lot of effort to open the box on the outside, and there was a transparent mezzanine inside, we didn't move, and we locked the box after reading it. ”

"That is, the outer box is open, the isolation box has not been opened, if the outer box is closed at the back, it is not a big problem, take us quickly."

Liu Yan grabbed a handful of the tattooed man's hair and fell out very badly: "He was irradiated, this hair fell out so badly." ”

The young man who came with Qiu Zhongtian took out a measuring instrument, checked the tattooed man, and said after a probe: "Being slightly irradiated, there is no danger to life, but the hair has to fall out, and there will be problems with childbirth in the future, which may lead to fetal malformations." ”

The young man probed several others: "They have not been irradiated, they should not have been exposed to the source of the radiation." ”

Liu Yan said to the tattooed man again: "Did you hear that? Now you know that you regret it, right? Who else is exposed to cobalt-60? ”

When the tattooed man heard that he was going to have children, he was about to cry: "I didn't let them see it, Brother Zhuang and we both watched it." ”

Liu Yan heard it: "Zhang Zhuang also came into contact?" ”
