Is the frequency emitted by high-frequency plastic heat sealing machine harmful to human body?

Someone should have read Sina's blog 1999065438+ 10/2/0/.

Electromagnetic radiation pollution threatens life safety.

Our reporter Hu Qifeng

After water pollution, air pollution and noise pollution, electromagnetic radiation pollution has spread all over the world.

It is considered to be the fourth largest pollution in the world. "We will establish research on electromagnetic radiation pollution control in Beijing as soon as possible."

Heart' ",also become today by Beijing Academy of Social Sciences, Beijing CPPCC Proposal Committee, Beijing.

At the "seminar on electromagnetic radiation pollution and protection" jointly organized by the Institute of Labor Protection Science.

Issues of concern to many experts.

According to reports, the purpose of holding this seminar is to make the Beijing Municipal Government pay attention to electromagnetic prevention and control.

The policy on radiation pollution has more scientific basis, and some Municipal People's Congress representatives and CPPCC members attended the meeting.

After listening to the arguments of many environmental experts, the researcher thinks that due to the concealment of electromagnetic radiation pollution,

It is not easy to be taken seriously, because developed countries have formulated corresponding management methods and technologies.

Technical standards, it is suggested that the Beijing municipal government should also deal with the production environment, electrical appliances and electricity consumption that produce electromagnetic radiation.

Sub-products, electromagnetic wave protection products and construction planning of radio stations, TV stations and high-voltage power transmission and transformation.

And related commodity import and export industries and departments, the introduction of management measures and technical standards. a lot of

Experts call for solving the problem of electromagnetic pollution disturbing people, preventing interference and pollution hazards and meeting needs.

Computer room, command room, aerospace, weapons and equipment, missile spacecraft, satellite communication system,

Telegraph and telephone room, radio remote control and measurement system, ground station, precision instrument room and other nationals.

The economic and national defense departments urgently need electromagnetic protection and develop new electromagnetic protection.

Materials, antistatic materials, design new electromagnetic shielding room and other practical products, and establish "Beijing"

The research center for electromagnetic radiation pollution control is very necessary, and I hope the relevant departments will consider it as soon as possible.

According to Zhao Yufeng, director of electromagnetic compatibility and protection research office of Beijing Institute of Labor Protection Science.

According to its introduction, electromagnetic radiation pollution is mainly caused by high-voltage transmission lines, short waves, ultrashort waves and microwaves.

Wave, electronic game machine, video display, mobile phone and other mobile radiation sources.

When the telephone receives the call, it receives the radio wave signal from the base station, which affects the people in the affected area.

It's not big, but when the mobile phone cradle speaks, sound waves are converted into high-frequency electric waves through the mobile phone, and electrical signals are transmitted.

When transmitting, strong high-frequency microwave radiation will be generated near the transmitting antenna at the top of the mobile phone.

Many experts believe that shooting will affect the head health of users. It has happened many times at home and abroad so far.

An incident of electromagnetic radiation pollution occurred. The United Nations Conference on the Human Environment has made a decision to prevent and control electromagnetic radiation pollution.

As one of the environmental protection projects, it is called reducing electromagnetic radiation pollution and preventing interference and destruction.

Higher and higher.

First, dangerous events caused by strong electric fields generated by high-voltage transmission lines.

1. There is a new building 60 meters above the ground in a town in upstate New York, USA.

When high-voltage transmission lines pass by, sometimes they often hear the sound of "scratching". One night,

It was dark, and people gathered under high-voltage lines, holding a fluorescent lamp in their hands.

noodle As a result, all the lights in my hand are on. People are more uneasy. Some people say:

"This is too worrying. The wire is as high as 60 meters from the ground, and the electromagnetic energy radiated by it is unexpected.

Fluorescent lamps can emit strong light. Whether living in this environment is safe and reliable,

Will it cause cancer? Doubtful, I hope experts will investigate and study. "

There is a farm in Minnesota, USA. 1978, a power company carried it out of the farm.

A 765 kV high-voltage transmission line was set up, and power transmission officially started.

Because this transmission line has a large current, it is 15 meters below it.

The intensity of the formed electric field is as high as 1 10,000 volts/meter, and people often hear the sound of "snapping".

Because of the powerful electromagnetic energy emitted by power lines, people find plants under power lines.

The leaves withered, which affected the growth and development. Under this power line, if the human body and

When tractors or other iron tools come into contact, there will be a sense of contact between electric sparks and body parts.

To pain. People who work below often find that their hair stands on end because of the electric field force.

The farmer Marilyn Guluba and her husband both demanded an investigation.

They said, "Since the construction of this transmission line, the electromagnetic waves it emits have made us feel as if there is one."

Spiders crawl on the body, which can be heard by human ears and felt by skin.

It works, but the eyes can't see it. "

3. A scientific research report published by1993 with relevant survey data of the three Nordic countries pointed out that,

When the electromagnetic field generated by transmission lines reaches more than 2 milligauss, the incidence of infant leukemia increases.

Adding 2. 1 fold, the incidence of brain tumor increased by 1.5 fold.

4.199365438+1October 30th, scientist, Karolinka University, Stockholm, Sweden.

Scientists surveyed 430,000 residents living near high-voltage power lines for a long time, and published a survey result.

Research results. Scientists have clearly pointed out that radio waves are related to cancer, especially brain tumors and childhood leukemia.

Blood diseases are directly related.

The second is the harm caused by electromagnetic radiation generated by short wave and ultrashort wave.

1, a typical example happened in Chicago, Illinois.

In order to meet the needs of research and teaching, the Institute of Technology spent one hundred thousand dollars to build an advanced electronic scanner.

The results of the tracking telescope are disturbed by the ultrashort wave electromagnetic radiation emitted by nearby TV stations.

The electronic scanning telescope is broken and can't be used.

This kind of similar interference incidents have occurred frequently in the United States, Japan, West Germany and other countries. Therefore,

Automatic control device failure, high-speed electric locomotive misoperation or derailment, aircraft navigation

Accidents and economic losses are caused by the error of missile guidance system or the interruption and failure of contact.

2. In the United States, due to the serious electromagnetic pollution in the local environment, the disease of placing pacemakers is caused.

People are in trouble. It happened that the pacemaker was under the action of electromagnetic field environment because the pacemaker worked.

The frequency is destroyed, and the patient's heartbeat rhythm is seriously disordered. This kind of event

Many heart patients are very uneasy about this.

Third, the harmful events caused by microwave radiation.

1 In the early 1970s, there were1microwave pollution incidents in Japan, almost worldwide.

The shell causes vibration and anxiety. At that time, the soldiers who operated and used radar were all sick.

Health is obviously exposed to occupational hazards, and it is pointed out that the radiation generated by radar is harmful to health.

Strongly protest, and all resign at the same time, "just work." Organize immediately after the incident.

After investigation, it was found that the microwave radiation emitted by radar was harmful to human body, and patients appeared.

Not radiation.

2. 1962, the CIA discovered a "strange radio wave" sent to Moscow.

Initiated by the American Embassy in the Soviet Union. This "strange wave" is similar to the microwave emitted by radar.

The Soviet authorities consciously walked from two buildings across the street from the American Embassy in the Soviet Union to the Embassy.

The building started it. Later, the Soviet Union cited "drinking water in Moscow as a cause of disease"

Therefore, the requirements for testing blood samples are put forward. The test results show that one third of people have total white blood cells.

The number has increased by nearly 50%, which is one of the characteristics of leukemia. Later, the CIA used

The monkey did an experiment under the same conditions. After three weeks, the monkey's nervous system appeared.

Systemic and immune system disorders. People who have worked in this embassy have an obvious incidence of cancer.

Significantly higher than the normal average, two people died of cancer.

1976, the State Council designated the U.S embassy in the Soviet union as "an important place to protect health". To prevent

The microwave oven came into the office, and all the windows were shielded with metal.

The "strange radio waves" in Moscow continued until May 1979.

Fourth, the electronic game machine interference incident.

Electronic game machine is a kind of strong electromagnetic radiation source, and most products on the market at present.

The intensity of radiation field exceeds the national standard. Radiation radius 100m, used for TV programs and wireless.

Communication causes serious interference and damage.

The roller coaster in an amusement park in Japan was created by another video game machine nearby.

Electromagnetic radiation interference has destroyed the normal work of the roller coaster program control system, leading to roller coasters.

Suddenly derailed, causing many casualties.

Fifth, the radiation hazard event of video display.

It is precisely because of the large number of electronic computers and color TVs put into use and the frequency of use.

The speed and time are greatly increased, and the electromagnetic radiation of video terminal display is harmful to human health.

The influence and harm have aroused people's general concern and strong response.

On the influence and harm of electromagnetic radiation of video terminal display to human health, the world

Many countries, such as the United States, Britain, France, Germany, Canada, Japan, Sweden and New Zealand.

Singapore, Norway, Australia and other developed countries organized forces and made a lot of research findings.

VDT mainly damages sensitive organs and parts such as eyes, head, skeletal muscle and skin.

In addition, it also has adverse effects on pregnancy.

Typical examples of this are:

1, 1985, refugees et al.

395 workers exposed to VDT were investigated, who worked 5 hours a day.

After a period of professional operation, there will be eye discomfort, skeletal muscle discomfort, headache and skin discomfort.

Discomfort and other symptoms, the above four symptoms are significantly different from the control group.

2, Massachusetts Bank, communications, computers, hospitals, public enterprises, state federation.

There are 1545 workers exposed to VDT for 0.5-7 hours every day in six industries.

It was found that there were three major symptoms: eye discomfort, skeletal muscle discomfort and headache, which were significant compared with the control group.

Difference. Most VDT workers have temporary myopia and their vision is greatly reduced.

Sixth, the radiation hazard of mobile phones.

1, due to improper use of "mobile phone", brain tumors and other diseases occur from time to time. This is in

It has been confirmed that North America and Western Europe are the first to use this technology. Most seriously,

The perennial users of "mobile phones" suffer from brain malignant tumors. An Italian entrepreneur used the word "big"

Columbia "wireless phone, the work efficiency has been greatly improved, but three years later, his brain was discovered.

Malignant tumor, diagnosed by CT scan, the lesion is located at the wireless top of the "mobile phone"

I used to put it nearby. At the beginning of last year, an American businessman made the same discovery after using "mobile phone" for four years.

Now there is a tumor in the brain. After many treatments, he died of illness. His widow is very sad.

Apart from the pain, I have decided to sue the company that produces this kind of wireless phone. This incident has been in the United States.

Cause shock waves and let people know "Big Brother" again.

2. A husband accused the mobile phone manufacturer.

The malignant brain tumor caused by radiation microwave radiation took the life of his wife.

David Leonard of Madeira Beach believes that Susan Leonard (33) is due to

On May 24th, she died of malignant tumor and the mobile phone he gave her. Yes, this phone.

The company's manufacturer, Nippon Electric Company, sued and accused the tumor of being long enough to cause

Life, because the mobile phone "antenna position is improper, leading to the discovery of the brain where the tumor is located.

Received unsafe microwave radiation. "He claimed that the location of the tumor happened to be a phone call.

When the telephone antenna is found.

3. There have been many accidents in Japan in which mobile phones interrupted the work of infusion pumps, ventilators and electrocardiogram.

Surveillance and other interference hazards. At present, Japan has banned the use of mobile phones in hospitals.

Some interference events caused by electromagnetic radiation pollution in Beijing

(1) 1976 Electromagnetic radiation generated by Beijing XX transmission tower to surrounding residents.

Interference and pollution incidents. Beijing XX radio transmitting station is adjacent to residential areas and schools, because

The broadcast antenna is 0/00 meter away from the school and residential area/kloc. Therefore, this school has more than 100 teaching staff.

Workers and thousands of students jointly complained to the National People's Congress and the All-China Women's Federation and sued themselves.

Radiation is very harmful.

(2) High-power electronic impact of plastic printing occurred in the plastic printing workshop of Beijing No.3 Trademark Printing Factory.

There are nearly 20 devices, which will produce serious electromagnetic pollution when working.

Because the workshop is close to the residential building, this electromagnetic radiation causes electricity to the surrounding residents.

The TV set can't be listened to normally, and some residents simply put away their newly bought TV sets.

Contradictions continue to develop. To 1980, the residents of the annex jointly complained and directly intervened in production.

Warning: "No construction is allowed until the danger is solved".

(3) Dongcheng No.1 Plastic Factory is located on the east side of Beijing Gulou, adjacent to the factory.

More residents, the electromagnetic radiation of the heat sealing machine directly affects and destroys TV viewing and

Listen, the residents have a lot of complaints.

(4) The General Staff Headquarters of Tongxian County has an early warning radar. When the radar works, it is built.

Radiation pollution to the surrounding environment within several hundred meters. A TV set in the office was stolen.

"burned" two sets, and cable broadcasting was seriously disturbed; Xx CCTV image network department

System, equipped with multiple 586 microcomputers, NOVAJET.4 plotter, scanner, CD engraving machine,

Television editing machine, camera and other equipment. In the process of work, mistakes are often made due to radar interference.

Some work cannot be carried out, resulting in loss of people, money and materials. For example, in video editing.

Surface, radar waves have made the work impossible, so we must leave the station and transport the equipment to Tongxian County.

Rent a house in town as an editor.

(e) "Mobile" interference hazards

1from June to July, 1996, the infusion pump in Beijing medical system failed three times during the treatment.

Suddenly interrupted the accident. After investigation, the cause of the accident was due to the use of "big brother" by the family members of patients in the ward.

Caused by "big" radio interference.

Infusion pumps, ventilators and ECG monitors are commonly used equipment in hospitals, which are mostly used for critical diseases.

People's rescue is extremely dangerous. Therefore, some developed countries have clearly stipulated that in hospitals,

It is forbidden to use "mobile phones" in airplanes and other systems.

A scientific research unit in Sweden studied the electromagnetic radiation field strength of common household appliances.

Measurement, the results are listed in the table below:

Electromagnetic wave intensity (unit: micro Tesla)

3 cm 30 cm 1 m
