Gu Yanan asked one of the workers who was sorting out old clothes, "Have you recently taken out a small metal ball from the pocket of your old clothes, round, about a little larger than the glass marbles that children usually play with, gray-white, it feels very heavy in your hand, and it will glow blue in dark places." ”

One of the four workers in the scrap yard who sorted out the old clothes was an aunt in her 50s, and one of them said, "We take out all kinds of things from the old clothes every day, but they are useless, and the useless things are thrown in the garbage basket next to us." ”

Another aunt said, "Yesterday I took out a small ball from a bloody garment, which was similar to what you said, but it was daytime, and I didn't see it glow blue, and it was heavy in my hand, heavier than a steel bead, and I looked at it at the time and thought it was useless, so I threw it in the trash." ”

"Which trash can?" Gu Yanan hurriedly asked.

Auntie pointed to a trash can next to her, "This is it." ”

Gu Yanan leaned over and saw that there were some miscellaneous things in the garbage can, which were detected with a radiation detector, and there was no sign of radiation exceedance.

Gu Yanan asked again: "What about the things before in the trash can?" ”

"It was taken away by the garbage truck, and our garbage here is also cleared every day."

"Where does the garbage truck go?"

"It will be sent to the garbage transfer station in the Donghu community first, and then it seems to be sent to the landfill outside the east city."

Gu Yanan and Gao Fei drove to the garbage transfer station in the East Lake community.

After revealing their work permits, the two began to conduct radiation tests around the transfer station.

Everything is normal and there are no signs of radiation exceedance.

Gu Yanan asked the staff of the garbage transfer station, "What about the garbage delivered yesterday?" ”

"It has been sent to the landfill outside Dongcheng early this morning, and at this point in time, yesterday's batch of garbage should have been buried in the ground."

Gu Yanan and Gao Fei drove to the landfill outside Dongcheng again.

Outside the gate of the landfill, the two got out of the car and turned on the radiation detector, only to hear a screeching siren from the detector.

Sure enough, there was a radioactive source in the landfill.

Gu Yanan called the staff of the landfill and asked where the garbage brought in yesterday was buried.

The staff pointed to a large deep pit in the landfill and said, "The garbage from yesterday is buried there, but there is too much garbage, and the landfill is very deep, and it is not easy for you to find something." ”

Gu Yanan listened to the alarm of the radiation detector, "Even if you dig three feet into the ground, you have to find the source of radioactivity." ”

Goofy looked at the huge landfill and wondered, "How long will this be dug up?!" ”

Gu Yanan: "I want to find an excavator to help, and at the same time notify my colleagues in the radiology department to bring a few more sets of protective clothing." ”

At the same time as the landfill was blocked and the excavator was mobilized, Wang Xiaoxiao called.

Wang Xiaoxiao has received exact information from the Environmental Protection Bureau that the source of the radiation was lost at a breeding station on Niushan Island.

In order to breed, the breeding station was approved in the first half of the year to purchase two cobalt-60 radioactive sources.

The radioactive source is only used during the breeding season, and when it is not in use, it is placed in a dry well in the backyard of the breeding station, and an old man is hired to guard it.

Unexpectedly, a few days ago, someone thought that there was a treasure in the dry well, so they opened the old man who guarded the door, poisoned the earth dog guarding the door, and stole the radioactive source.

Because the scene was faked as if no one had ever been there, the old man of the old guard did not notice anything unusual, and it was not until the Environmental Protection Bureau issued a notice that the breeding station came to check the radioactive source, and it was discovered that the radioactive source had been stolen.

It was confirmed that there were two cobalt-60 radioactive sources in the dry well, one large and one small.

The one that Wang Hongyun sold to Zhang Feng's jewelry store was a larger one, while the one that Wang Youcai carried, which is now buried under the landfill, was the smaller one.

Finally determined the source and type of radioactive source, Gu Yanan began to arrange for relevant personnel to excavate and find work in the landfill.

Three hours later, when it was completely dark, several groups of people took turns to dig out the small ball that shimmered blue in the deep landfill pit.

A second lost source of Cobalt-60 was found.

Lianhai Center for Disease Control and Prevention, Emergency Office.

Gu Yanan is writing a report on the loss of the radioactive source.

Wang Youcai and Wang Hongyun, residents of Niushan Village on Niushan Island, had the idea of stealing because they heard from the old man Wang who was guarding the door that there were treasures in the dry well in the backyard of the breeding station.

After Wang Youcai and Wang Hongyun combined, one dragged the old man Wang who was guarding, and the other went into the backyard to steal.

The two discovered the cobalt-60 radioactive source hidden in the dry well, but they did not know what the two metal balls were, nor did they realize the danger, and mistakenly thought that the blue glowing thing was a sapphire.

Wang Youcai took one of the radioactive sources and put it under his pillow, and after a night of radiation, he died by a garbage can on the way to the health center the next morning.

Wang Hongyun sold one of them to Zhang Feng's jewelry store.

Wang Hongyun was exposed to radiation for more than 10 hours because he kept the radioactive source in his pocket, and he died within 24 hours of being admitted to the hospital.

The boss Zhang Feng also thought that the small ball with blue light was a sapphire, and it was specially stored in the bedside table in the bedroom.

Zhang Xiaofeng, the son of Zhang Feng's jewelry store, who used the radioactive source as a toy marble, had his hands amputated because he directly touched the radioactive source with his hands for nearly half an hour, although he was treated in time and saved his life.

Zhang Feng's wife and parents were also hospitalized because of different degrees of radiation, and the prognosis was good because of timely treatment.

The police officers responsible for handling the death of Wang Youcai, a thin man on Niushan Island, were also exposed to different doses of radiation, and after being admitted to the hospital for treatment, the prognosis was good.

The First People's Hospital of Lianhai City.

Gu Yanan carried the cooked porridge and visited Nan Hanfei, who was hospitalized due to radiation.

Seeing Gu Yanan walk into the ward, Nan Hanfei put down the mobile phone in his hand and said with a smile: "This is the second time you have come to the hospital to bring me porridge." ”

Gu Yanan propped up the small dining table on the hospital bed and put the porridge on it, "I don't want to come back next time." ”

"You don't want to come and bring me porridge?"

"I don't want you to be hospitalized again!"

Nan Hanfei smiled happily and began to drink porridge by himself.

Gu Yanan watched Nan Hanfei drink porridge and sat next to him to peel apples for him.

While seeing Nan Hanfei drinking porridge, he also glanced at his mobile phone from time to time, Gu Yanan asked, "What is there on the mobile phone that makes you so fascinated?" ”

"It's what you wrote."

"I wrote it? What the? ”

"There are two Moments of Friends, Friends of Infectious Diseases, and Friends of Chemical Agents, which are interesting and good-looking."

"If you like it, there will be a third article soon, which is about this radioactive source."

"Then I'm looking forward to it."
