Radiation from wind power can cause cancer, and thenoise pollution caused by wind poweris 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 developmental process that includes genome instability and abnormalities in the mechanisms of multiple signal transduction pathways related to cell proliferation.
Ionizing radiation is a natural genotoxic agent that can directly penetrate tissues and cells and deposit energy randomly. Therefore, hisgenotoxic 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. They appear to be caused by multiple pathways and are random. 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 dozens of generations later. This type of mutation is not the result of the direct action of ionizing radiation. is genome instability.
Wind power can produce renewable energy, but it can also cause noise pollution.
There is radiationnts which can cause ionization and cause cancer.
Ionization occurs when electrons are knocked out of their electron shell by ionizing radiation, making atoms positively charged. Since cells are made of atoms, ionization can cause cancer. A cell is made up of approximately billions of atoms. The likelihood of ionizing radiation causing cancer depends on the radiation dose rate and the body's susceptibility to receiving the radiation.
Terrestrial satellite communications stations, large power plants, energy transmission and transformation equipment, high and ultra-high voltage transmission lines, subway trains and trains Electrics, as well as most household appliances, can generate various shapes and frequencies. , sources of electromagnetic radiation of different strengths.
Detailed information:
The main sources and effects of radiation:
1. Electromagnetic waves are composed of electric and magnetic fields that oscillate in phase and are perpendicular. Some as waves in space, its direction of propagation is perpendicular to the plane formed by the electric field and the magnetic field, effectively transferring energy and momentum.
2. Radar systems, television, mobile phone and radio transmission systems, radio frequency induction and medium heating equipment, radio frequency and microwave medical equipment, various electrical processing equipment, subway trains and electric trains, and most of household appliances. household appliances, etc. They can all produce various shapes, different frequencies and different strengths.degree of electrical radiation sourcetromagnetic.
3. Electromagnetic radiation fills space, is colorless, odorless and invisible and can penetrate many materials, including the human body. If the human body is exposed to a radiation dose that exceeds safety for a long time, cells will be damaged or killed over a large area.

What are the dangers of wind power plants?
Wind power can produce renewable energy, but it can also cause noise pollution, harming the health of local residents. Faced with growing public doubts, Health Canada decided to launch an in-depth study and establish a team of experts to study the relationship between low-frequency noise from wind energy and human health. Canadian Health Minister Leona Aglukkaq announced that Ottawa would lead the study in response to concerns from residents nears wind farms. Canada will spend $1.8 million to train a team of more than 25 acoustic and medical experts, including four international consultants, to investigate the situation of 2,000 residences living near 8 to 12 wind turbines.
Residents were forced to hide in basements to sleep.
“Currently, there is insufficient evidence to prove the relationship between noise from wind turbines and the adverse effects on human health, but Health Canada and certain scientific publications have in fact documented certain nuisance problems caused by the production of wind energy in communities," the ministry said in a press release. However, Sherri Lange , CEO of the North American Platform Against Wind Energy, claimed that low-frequency noise and vibrations produced by wind turbines can cause sleep disturbances, headaches, depression, anxiety andé and even blood pressure problems.“The house vibrated like a guitar resonance,” Lange said
, residents were forced to flee into basements to sleep or sleep in the yard. To his knowledge, 40 families in Ontario have left wind farms because of this. This . There are currently 140 wind farms equipped with wind turbines across Canada, most of which are located in Ontario and Quebec.

1. Wind power generation will harm the local ecological environment, e.g.example by destroying vegetation, changing the topography and causing damage to the 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 wind farm 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 a phase shift signal, which may impact the FM radio system. The material the blades are made of will also interfere with electromagnetic waves. If the blades are made of metal materials, it will cause damage.e 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 consumption 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 driver of 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 relativelyt high, a huge tail of water vapor will condense behind the wind turbine, which can affect the local microclimate, 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 limited bending moment, torque, shear resistance and extrusion that the blade root can withstand, in severe cases the entire blade may 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 the blades to break, causing accidents and affectant 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.
Wind blade noise can be roughly divided into three categories.
1. Thick noise, produced by the compression of the air and the blades. In windy weather, when we close the doors 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, i.e. when the Mach number is produced near 1. In this way, the impact of noise on the environment cannot be ignored.

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 power generation, environmental, economic and social effects must be considered comprehensively, and one cannot ignore the other. The impact on the environment must be reasonably taken into account in both its positive and negative aspects.
