What is the unusual use value of this pile of "iron tuotuo", which made Townsend be sentenced to such a heavy sentence? Why do people who know the truth start to sweat?
When the alarm came, the police of the Provincial Public Security Department quickly set up a major crimes unit.
At 9: 00 am on February 27th, 2002, the staff of Panzhihua 502 Power Plant was informed to inspect a batch of dangerous machinery and equipment in the basement of a villa around Laohuigou. No one wants to come to this remote corner, because the workers in the factory are idle, not only because there are weeds here, but more importantly, there are a number of machinery and equipment-63 cobalt 60 radioactive sources. However, when the staff opened the basement of the villa, the situation immediately made him sweat. The 63 Co-60 radioactive sources originally stored here were looted, and the 14 lead packaging shell of the radioactive sources was also lost.
Cobalt -60 radioactive source has very strong radiation ability, and it is very likely that ordinary people will die immediately after a few minutes of close contact. If this large number of radioactive sources are injected into social development, lost in rivers or smelted into stainless steel plates, the losses will be difficult to estimate.
After receiving the alarm, Panzhihua City Public Security Bureau immediately dispatched a group of experienced police officers to form a major case of cobalt theft, and started the province's public security police and security personnel to carry out carpet search. After receiving the report, the Ministry of Public Security only issued an instruction: the local public security department should solve the case within a time limit!
After seven hours of investigation, the ignorant thief realized that he had made a big disaster.
The project police quickly obtained the clues of the case, and a waste recycling station collected 14 lead bullets. There is no doubt that these lead shells were stolen and used to hold cobalt 60 radioactive sources. Even if the case was broken by half here, on the morning of 27th, around 10, the police of the major crimes unit arrested Dong Hewang, who was selling these lead bullets. At about 4 noon, the first offender who stole Cobalt 60 was arrested. In addition, 63 stolen cobalt -60 radioactive sources were all recovered without any harm, and all cases were solved in only 7 hours. The first offender, Townsend, was sentenced to 1 1 year imprisonment, and Xie Xiaorong was sentenced to1year imprisonment.
According to the interrogation, Thomson, the first offender, was a temporary worker in the 502 power plant, and his family just wanted to make furniture out of wood. He didn't realize that the 502 power plant where he had worked before had piled up a lot of wood around Laohuigou, so at 2 1 on February 24th, Townsend colluded with Xie Xiaorong and Dong Xiaoping to steal wood from Laohuigou according to the sewer pipe.
If they only steal two pieces of wood, they are unlikely to be in such a prison. When they were looking for wood, they accidentally found that the basement door of a villa was unlocked. When they entered, they found a pile of "iron bumps". The three mercenaries colluded and sold 63 radioactive sources and 14 lead shells together, regardless of the danger signs.
What makes people laugh and cry is that they feel that they have stolen a batch of scrap iron from beginning to end. Among them, Dong Xiaoping's brother Dong Square saw the scrap iron brought back and felt "tricky". So he bought 14 lead bullets from his nephew for 2 pounds. 2 yuan, 26, sold to the scrap collection station at the price of 6 yuan. Other radioactive sources hidden in various places were not even ready to start, and the police came to the door. At this point, this group of thieves realized that they were not stealing "iron bumps", but only radioactive sources at dangerous times. If the protective cover outside the radioactive source is cut off, they may have been robbed of their lives, and the immediate arrival of the police saved them.
Why is the cobalt 60 radioactive source so destructive?
This case has alarmed the public security police in all cities, which is not a fuss. Many people are not familiar with the cobalt 60 radioactive source. The radioactive substances they mentioned are radioactive sources that they think only nuclear power plants and nuclear bombs will cause. However, with the increasing use of nuclear weapons, this seemingly dangerous and mysterious radioactive source has already entered the daily life of most people.
Cobalt 60 is a radioactive substance radionuclide of the chemical element cobalt, which does not exist in nature. Generally speaking, it is obtained by irradiating cobalt in an atomic furnace for a medium time. At present, China's cobalt 60 radioactive source can be produced in the heavy water reactor of Qinshan No.3 nuclear power station. Although the processing technology of cobalt 60 is relatively simple and the cost is not high, it does not damage the huge destructive power of cobalt 60.
Cobalt 60 causes two kinds of high toughness radiation and has strong radiation source ability. This radiation source has a key influence on the genetic information of somatic cells, leading to chromosome aberration, cell death or failure to carry out all normal copy disintegration. According to this unique function, cobalt 60 is generally used for disinfection and food disinfection, which is why many vacuum-packed foods are originally marked as preservative-free. But even if it is not easy to rot for a long time, Chengdu-Chongqing's 20 billion-scale braised chicken feet industrial chain is basically disinfected by radioactive sources. Food crops that are easy to germinate, such as garlic, will always lose their germination ability under the direct irradiation of cobalt 60.
Improving efficiency by using low-charm cobalt 60 radioactive source
In industrial production, cobalt 60 is also used as a way of nondestructive testing of stainless steel plates, which measures the aspect ratio, thickness and relative density of raw materials. Ordinary seamless pipes will use radioactive sources such as cobalt 60 to check cracks and bubbles before leaving the factory to ensure the quality and quantity pass.
Cobalt 60 is powerful, but it does great harm to the body, especially in the places where the theme is full of activities, such as blood night and spinal cord. After the human body is exposed to cobalt 60, there will be mild radiation diseases such as rash, soft spots, hair loss and leukopenia, and if the radiation source is too strong, it will die immediately. In response to the powerful charm of cobalt 60, the survival time of the body may be about five minutes. The weak charm of cobalt 60 will cause a large area of body collapse and the rupture of capillaries, which will cause the world to fall into extreme pain. Even a slight touch will have no symptoms for a short time, but it will also have an impact on genetic information.
1992 cobalt 60 was taken by mistake. Although cobalt 60 has been damaged in drug half-life for 5.27 years, it still caused three deaths, and 14 1 people's physical and mental health was affected. So all the radioactive sources were lost, not to mention 63 pieces at once.
abstract
The horror of radioactive sources is not only invisible, but also the surface and appearance of all radioactive sources are the same as ordinary objects. Cobalt 60 is generally made into particles and encapsulated in a cylindrical stainless steel plate, while iridium 192 is generally made into a mesh structure. If it is not for the risk specification of thick protective cover, it is not worth mentioning that radioactive sources are placed in every corner.
Some time ago, there were several cases in China where radioactive sources were lost and picked up by others as small objects, causing different degrees of damage. What is even more worrying is that up to now, there are still 2,000 radioactive sources missing in China.
