Do wind power plants emit radiation and does it affect people?

We sometimes see groups of windmill-like buildings in nature. These are wind power plants. Using wind energy to generate electricity is very environmentally friendly, and wind energy resources are abundant. Wind energy therefore plays an important role in our lives. Wind power plants use clean and harmless wind resources. During the process of generating electricity, they do not produce radiation like nuclear power plants do, so they will not have any impact on the human body.

The principle of using wind energy to produce electricity is: the wind causes the blades of The windmill to rotate and the speed increases due to the increase in speed, thus converting the kinetic energy of the wind into mechanical energyue, then the mechanical energy is converted into electrical energy, prompting the generator to produce electricity. The wind wheel of the windmill is an important part that converts the kinetic energy of the wind into mechanical energy, and the iron tower is an important structure that supports the wind wheel, rudder and generator. With wind turbines, even a breeze with a speed of just three meters per second can be harnessed to start producing electricity. The higher the wind force, the greater the kinetic energy of the wind and the greater the economic benefits generated by wind power plants. In the plateaus and coastal areas of northeast, northwest and southwest China, wind resources are particularly abundant. It is very significant and promising to develop wind power plants in these areas.

Wind power plants can be dividedes into the following types: The first type is a vertical axis wind turbine. The structural design of this generator is simpler than other generators. other conditions are certain, the power supplied by this generator is less; the second type is horizontal axis wind turbine, which can be divided into two types: doubly powered generators are more commonly used; It is also a dual-fed generator, which is increasingly used in wind power generation due to the development of electrical technology.

Wind power generation uses clean and renewable wind energy resources, which will not be depleted or pollute the environment. In addition, the construction period of wind power plants is short and it is not necessary to invest too much human and material resources. However, wind power plants also have their drawbacks. They mustent occupy a large area of ​​land and, as they rely on natural wind resources, their electricity production is actually unstable and affected by natural conditions. During operation, wind power plants will also produce noise, which will affect the lives of surrounding residents to a certain extent.

Radiation from wind power generation may cause cancer

1 Wind power generation will harm the local ecological environment, for example by destroying vegetation and modifying the topography. , and causing soil erosion.

2. Electromagnetic radiation produced by wind power generation affects human habitation. In wind power generation systems, generators, substations, transmission lines, etc. are the main causes of electromagnetic radiation. When the receiving device attached to the eo parklink receives the signal, it will receive the electromagnetic wave signal reflected from the wind turbine blades.

The reflected signal is a delayed signal which may have a greater impact on the AM radio system. At the same time, the rotation of the turbine blades will also produce an out-of-phase signal which can affect FM wireless systems. The material the blades are made of will also interfere with electromagnetic waves. If the blades are made of metal materials, it will cause serious electromagnetic interference.

In addition, an alternating electromagnetic radiation field will form around high-voltage transmission lines, causing electrostatic induction relative to the ground, causing radio interference and affecting human health.

3. Wind energy affects the local climate. Wind energy uses wind energy present in the atmosphere. According to the law of conservation of energy, the conconsumption and production of one type of energy must produce or consume another type of energy. Therefore, wind turbines The electricity generation process must consume some of the wind energy present in the atmosphere. As an important factor in climate change, changes in wind energy will inevitably lead to climate change.

When some offshore wind farms and inland wind farms are operating, if the humidity is relatively high, a huge tail of water vapor will condense behind the wind turbine, which may affect the local microclimate, such as humidity, sand and dust have an impact.

4. Wind turbine blade damage is prone to accidents when the wind turbine blades are subjected to strong winds above 25m/s (wind speed cut off), although the wind turbine is in a state of stop. However, due to the bending moment, torque, resistanceance to the limited shear and extrusion that the blade root can withstand, in severe cases the entire blade can fly away.

Causes casualties and damage to buildings on the road (although wind turbines are mainly located in coastal areas with sparsely populated areas). In addition to extreme winds, blade surface corrosion, lightning strikes, ice cover, cracks, etc. can occur. can easily cause blades to break, causing accidents and affecting public safety.

5. Noise risks linked to wind energy production. For a wind turbine of such size, when the huge blades rotate (one blade requires a special long collapsible truck to transport), noise is inevitable.

The sound of wind blades can be roughly divided into three categories.

1. Thick noise, produced by the compression of the air and the blades. On windy days, when we close thedoors and windows, we often hear a sharp, harsh sound, which sounds like a ghost. crying or a howling wolf? , coupled with the gloomy sky outside, it's still a little scary to think about it.

2. Load noise, as the name suggests, is caused by the blades carrying a large load.

3. Impulse noise is generated when the Mach number is close to 1. In this way, the impact of noise on the environment cannot be ignored.

Detailed information

Risk response measures:

1. The construction of a wind power plant requires preliminary planning. It should be far from feasible. residential areas and avoid environmentally sensitive areas.

2. Improve the design level of wind power generation so that it can be well integrated into the environment.

3. When developing wind energy production, the environmental effectsonal, economic and social issues must be taken into account comprehensively, and any one of them cannot be ignored. The impact on the environment must be reasonably taken into account in both its positive and negative aspects.

The influence of wind energy can cause cancer, and at the same time, radiation caused by wind energyNoise pollutionis also harmful.

Environmental carcinogenesis mainly includes three major factors: physical, chemical and biological factors. Radiation carcinogenesis is the wide-ranging effect of ionizing radiation, and the occurrence of carcinogenesis is a very complex process. Radiation carcinogenesis is the result of the interaction between radiation factors and the body. It is a progressive development process that includes une genome instability and abnormalities in the mechanisms of multiple signal transduction pathways linked to cell proliferation.

Ionizing radiation is a natural genotoxic agent that can directly penetrate tissues and cells and deposit energy randomly. Therefore, its genotoxic effect on the body is different from that of chemical agents. Any tissue or cell in the body can be attacked by ionizing radiation. The severity of damage and biological consequences are linked to the radiation dose.

Radiation triggers cancer cells by damaging DNA molecules. This is not the effect of a single gene or a radiation-specific gene. This appears to be random and multi-path. Some of the genetic mutations caused by radiation do not occur in the irradiated cells, but in the descendant cells of the irradiated cells, even dizent generations later. This type of mutation is not the result of the direct action of ionizing radiation. is genome instability.
