Description of the problem:
I suspect that there is a very strong radiation near the home:
When you call, you can hear the sound of interference with the waves, that is, put the phone next to the speakers to text messages and phone calls is the sound
When you call, and sometimes even hang up, and other people immediately call in to show that: can not be connected
My cell phone is a mobile phone
What is going on here? How can I tell? How to determine its strength
Analysis:
To solve the radioactive sources around you to avoid radiation damage
? China Police Report reporter Li Xuerong Han Jinxing Wang Jian Beijing reported that the radioactive source is a radioactive material made of substances or entities that can produce radiation exposure. Since radioactive sources can cause damage to the human body when exposed to large amounts of radiation, and in severe cases can cause death, it is an emergency if the source is lost or stolen.
? May 25 this year, is located in Beijing Shijingshan District, Tianrui Hengda materials testing equipment Co. After receiving the report, the police immediately set up a task force to analyze the case, and a day later found the radioactive source and arrested the suspect. Although the case was quickly solved, it did cause many people to break out in a cold sweat. The stolen item was made of radioactive material, which produces radiation exposure, and if a large amount of irradiation is given to the human body, it may cause damage to the human organism, and in serious cases, it may lead to the death of a person. Such an important kind of goods, should be strictly custody is right, how can be stolen?
? In accordance with the "Chinese People's *** and the State Law on Prevention and Control of Radioactive Pollution" of the relevant provisions of the radioactive sources of the storage site should take effective fire prevention, anti-theft and anti-ray leakage safety measures, and designate a person responsible for custody. Radioactive source library not only to have an alarm and radioactive source library door key must also do double double lock, according to such provisions, radioactive sources to be stolen and not easy. So, how in the end was the radioactive source stolen? When the reporter interviewed the caretaker, he replied that, due to insufficient plug board, cooking the alarm power to pull down, and then forgot to re-plug. In this case, no wonder the alarm device does not work. Then how did the suspects get two different library door keys?
? Originally, for convenience, the key is fixed hanging next to the library door. Then, the key in hand, save the safe of radioactive sources and how to be opened? The results of the investigation is even more bizarre, it turns out that the key to the safe is inserted in the safe for a long time, and the password is a long time, and almost all the staff know.
? It is understood that it is such a state of custody, in the usual inspection of the relevant departments, but many times pass the inspection. According to the incomplete statistics provided by the Environmental Protection Administration, China's 1954 to now *** more than 1,500 radiation accidents of all kinds, an average of more than 30 accidents per year. And in recent years the loss and theft of radioactive sources in radiation accidents and accounted for the first place. In the first half of this year alone, there were 11 cases of loss and theft of radioactive sources nationwide. In response to this situation, the State Environmental Protection Administration, the Ministry of Public Security, the Ministry of Health on April 26 this year, jointly carried out a nationwide eight-month "check radioactive sources, so that people can rest assured that" special action to prevent radioactive contamination due to improper use of radioactive accidents.
? With the development of science and technology in China, the number of radioactive sources has increased dramatically. 2002 survey shows that the country has more than 8,300 units of radioactive sources, radioactive sources totaling more than 63,700, of which about 30% of the radioactive sources are not registered in the health sector for licensing, to be disposed of more than 13,800 discarded radioactive sources. State Environmental Protection Administration of Nuclear Safety and Radiation Environmental Management Division Director Li Ganjie introduced, now it is imperative to declare the registration of all units with radioactive sources, regardless of whether you are not in the past in the management of the department has done the license registration procedures, all requirements to declare. To find out the bottom of our country radioactive sources, so that we can really figure out the hidden problems, know the hidden problems in order to take corrective measures, in order to really eliminate some of the hidden problems Improve the level of security management of radioactive sources.
? These radioactive sources custodian unit of custody measures, really let us be afraid. Radioactive sources are directly related to people's health and national security, is a big problem that can not be ignored. For the general public, to understand the situation related to radioactive sources, learn some knowledge of handling radioactive sources, is also very necessary. When it comes to radioactive sources, most people are unfamiliar with them. Even the suspects who steal radioactive sources are mostly unaware of their harmful effects. In the case of the theft of radioactive sources in Beijing, the suspect did not know the harmful effects of radioactive sources, and after stealing the radioactive sources into his own yard, he and his loved ones were irradiated by the radioactive sources and suffered different degrees of physical illness. So, what exactly is a radioactive source? How to prevent the radiation of radioactive sources?
? The so-called radioactive source is a radioactive material made of substances or entities that can produce radiation exposure, such as hospitals used to treat cancer in some of the instruments and equipment used in the treatment of radioactive sources. Cobalt 60 is a radioactive element used in the treatment of cancer, but it is also a very penetrating element of nuclear radiation, and workers have to wear lead for protection when operating, and if they are accidentally exposed to radiation, they will be fatal.
? In the street interviews conducted by our reporter, we found that not only do few people know what the radioactive source is, even the sign of the radioactive source are few people recognize, some people even think it is a traffic sign.
? In accordance with national standards, all radioactive workplaces and radioactive sources of packaging containers must have such a warning sign, the purpose is to remind people not to casually touch these radioactive sources and radioactive workplaces. So, when we come across these suspected radioactive sources or radioactive sources, what should we do to prevent ourselves from being harmed? Li Ganjie, director of the Department of Justice, once you find a suspicious object, suspected that may be a radioactive source, do not go close to it, hiding in a shielded place, the distance as far away as possible, the third is as short as possible, do not stay next to the time too long. This way, even if a radioactive source whose shielding has been destroyed, it will not cause much harm to yourself.
? On May 29th of this year, Shanghai Jinshan County lost the flaw detector equipped with radioactive substances used for industrial production, which caused a lot of shock in the local area. However, Shanghai in the process of handling, not as in the past to send a professional team to quietly go looking for, but fully publicized to the masses.
? Experts told reporters that due to the different substances emitted, the harm of radioactive sources to the human body is not the same, according to the intensity of radioactive sources, generally divided into five categories of radioactive sources. The first category of radioactive sources are not shielded, or shielding is destroyed. If a person is exposed to it in close proximity, it may be fatal to the person in a few minutes to a few hours. If the source is a Category II source, the time may be longer, and exposure for several hours to several days may result in fatal injury. Now most of the radioactive sources used in China are class IV and class V sources, basically most of the sources are shielded, not ***. For human health, as long as you do not go to destroy it will not cause very direct and serious harm. So do not generalize, think as long as it is a radioactive source, as if it is very fear, there is no need to have a fear of mind.
? Then the people if they find suspected radioactive sources or radioactive sources, what should be done? Li Ganjie said, if the roadside encountered a discarded lead canisters placed there, as if a radioactive source of appearance, must be immediately to the relevant departments (public security departments, environmental protection departments) to report, provide information. The investigation of radioactive sources of special action, the environmental protection department also announced a hotline 12369, once received some information about the report, the environmental protection department will promptly send technicians, carrying instruments to the scene for proper disposal.
