Examples of electromagnetic radiation hazards to the human body around us:
On January 5, 2005, the first electromagnetic radiation health hotline in Sichuan Province was officially opened, and experts and scholars from universities such as the University of Electronic Science and Technology of China and Sichuan University answered inquiries from citizens. On the day the hotline was opened, it received dozens of inquiries from citizens, covering multiple aspects of electromagnetic radiation; In December 2004, the Sichuan Provincial Environmental Protection Bureau convened experts and citizen representatives to discuss the impact of electromagnetic radiation on the health of urban residents. This officially opened the prelude to the series of publicity work on radiation environmental protection in Sichuan Province, and a series of environmental protection actions against electromagnetic radiation were also launched one after another.
Various signs indicate that with the development of the economy and society, electromagnetic radiation facilities and equipment are increasing day by day, and more and more electronic products are entering the daily lives of citizens. Electromagnetic radiation is gradually receiving attention from people, but their understanding of it is extremely limited. Experts in Sichuan Province believe that it is particularly urgent to enhance public environmental awareness, guide citizens to correctly understand electromagnetic radiation, and eliminate blind panic among some citizens about electromagnetic radiation.
These electromagnetic waves fill the space, colorless and odorless, invisible, and can penetrate various non-metallic substances, including the human body. If the human body is exposed to radiation doses exceeding safety limits for a long time, cells will be damaged to varying degrees, posing a threat to the human body. Many readers have asked, "Have I encountered electromagnetic radiation?" The answer is yes. Everyone is exposed to electromagnetic radiation, but the strength varies.
Before 168 years, a British man named Faraday discovered a wonderful phenomenon where electric current passing through a medium can generate electric and magnetic fields, which later became known as electromagnetic induction.
From the first year of the last century (1901) when global communication began, to the widespread use of communication by the end of this century, electromagnetic radiation has penetrated into various aspects of human life and production.
Scientific research both domestically and internationally has shown that the main reason why electromagnetic waves can pose a threat to the human body is due to their thermal and non thermal effects.
Thermal effect: More than 70% of the human body is water, and water molecules rub against each other after being radiated by electromagnetic waves, causing the body to heat up and affecting the normal operation of organs in the body.
Non thermal effect: Organs and tissues in the human body have weak electromagnetic fields, which are stable and orderly. Once disturbed by external electromagnetic fields, the weak electromagnetic fields in equilibrium are about to be destroyed, and the human body will also suffer damage.
At present, there are two different views internationally on the impact of electromagnetic radiation on human health. One view is that long-term low-dose exposure is harmful to health; Another viewpoint holds that only by reaching a sufficiently high intensity can an impact be caused.
Survey: Chengdu residents in Sichuan are unfamiliar with radiation
Modern life cannot do without appliances. It can be said that electromagnetic radiation envelops every one of us. Xu Bin, Director of the Electromagnetic Environment Monitoring Room of the Sichuan Radiation Environment Monitoring Center, introduced that electromagnetic radiation pollution, also known as electromagnetic wave pollution, is generated by high-voltage power lines, substations, radio stations, television stations, communication equipment, radar stations and electronic instruments, medical equipment, automation equipment, and household appliances such as microwaves, televisions, computers, and mobile phones when working. But how much do citizens know about electromagnetic radiation? The reporter conducted a sampling survey. On the afternoon of February 2nd, the reporter randomly selected 100 citizens on Chunxi Road in Chengdu. Participants were asked to fill out a questionnaire with four multiple-choice questions on the spot, asking questions such as "Have you heard of electromagnetic radiation" and "Do you know that electromagnetic radiation is harmful". The data shows that although most people have heard of electromagnetic radiation to some extent, there are very few who understand the basic knowledge of electromagnetic radiation.
The first consumer complaint about computer radiation
In 2003, Liu Gang from Jianshe Road, Chenghua District, Chengdu, sued several computer manufacturers for computer radiation issues. At that time, the Chenghua District Court accepted this case, which was still the first in the country. It is reported that Liu Gang has been using computers since 1996, with an average of more than 2 hours per day. He learned from the Sichuan Radiation Environment Management and Monitoring Station in 2003 that improper use of computers at close range for a long time would pose great harm to human health. He believed that the lack of warning text on his products violated his right to know.
It is understood that the Sichuan Radiation Environment Monitoring Center receives several complaints related to electromagnetic radiation every day, and this number is still on the rise, indicating that electromagnetic radiation issues are receiving increasing attention from citizens.
Coincidentally, a few years ago, Mr. Xu spent nearly a million yuan in savings to purchase a 150 square meter commercial house. After moving into a new home, one after another was the anxiety and fear of the whole family. Like them, over 40% of the owners who first moved into the garden community experienced varying degrees of physical discomfort. After spontaneous investigation, they found that the problem lies in the medium wave transmission equipment next to the building. In June 2003, more than 100 homeowners voluntarily invited experts from the Beijing Environmental Protection Monitoring Center to inspect the environment of the residential area. The test results showed that 30 out of 42 measurement points exceeded the electromagnetic radiation standard. After repeated negotiations, the developer provided free installation of shielding nets to some residents who reported high radiation values, and finally signed an agreement to relocate the transmission tower with a certain unit that installed the transmission equipment on August 21 of that year.
Excessive radiation only causes harm to the body
Is electromagnetic radiation only one aspect that poses a threat to human health? According to Professor Lang Jinyi, Director of the Radiation Therapy Center of Sichuan Cancer Hospital and Chairman of the Sichuan Radiation Oncology Special Committee, the current development trend in the international medical community is that precision radiotherapy technology will dominate the field of radiation therapy in the future. Through more advanced technology, when radiation strikes various lesions with precision, it will minimize the harm it causes to other parts of the human body, that is, the side effects, as much as possible. So, currently radiation therapy plays an irreplaceable role in medical diagnosis and treatment.
Xu Bin introduced that electromagnetic radiation, as a physical phenomenon, has always existed in nature. From the perspective of human body functions, only when the radiation exceeds its limit will it cause harm to the body. In the fields of industry, science, and medicine, equipment accompanied by electromagnetic radiation is also widely used, which has played an important role in human production and life. The necessary knowledge of radiation prevention in daily life of citizens is indispensable, but there is no need to develop a fear of electromagnetic radiation.
The reporter recently learned from the Provincial Environmental Protection Bureau that Sichuan Province has included all kinds of mobile communication base stations in the scope of environmental monitoring. It is reported that there are about 15000 mobile communication base stations in Sichuan Province, with Chengdu accounting for about one-third. In the inspection and evaluation of six cities in southern Sichuan, including Chengdu, Yibin, Zigong, and Neijiang, less than 1% of base stations did not meet the national environmental protection standards.
According to Xu Bin, according to regulations, projects under construction should first apply to the Environmental Protection Bureau before construction, but the phenomenon of some projects being constructed before applying to the Environmental Protection Bureau still exists. This month, the Provincial Environmental Protection Bureau and the Radiation Center received reports that a certain power transmission line was illegally constructed without declaration or permission. They are currently investigating and collecting evidence, and will be dealt with in accordance with the law.
It is understood that the Sichuan Radiation Environment Management and Monitoring Center Station is the only radiation environment monitoring institution in Sichuan Province that has passed qualification and metrological review. Xu Bin suggests that citizens who suspect being exposed to radiation should first stay away from the radiation source and then consult and complain to the Sichuan Provincial Radiation Monitoring Center.
Long term use of computers harms women
Women who engage in computer related work for a long time have a 43% higher risk of developing breast cancer than non computer workers. This is a survey conducted in Taiwan, which shows that there are currently over 3 million computers in Taiwan, and the majority of computer workers are women. If you work in front of a computer for a long time, it will increase the risk of breast cancer; Women before menopause have a higher risk of developing breast cancer than women after menopause.
This study also found that humans are more susceptible to leukemia, cancer, and even miscarriage if exposed to certain electromagnetic radiation for a long time. Experts point out that using computers correctly can reduce their side effects on the human body. The human body should maintain a distance of no less than 80 centimeters from the computer screen and no less than 120 centimeters from the back and sides of the computer.
