All electrical products produce electromagnetic radiation. Generally, the electromagnetic radiation generated by electrical appliances can be ignored when it is 1-2 meters away. Nowadays, people often confuse ionizing radiation with electromagnetic radiation. , alpha rays, beta rays and gamma rays are produced, which are more harmful to the human body, especially X-rays that radiate over long distances. The main effect of electromagnetic radiation on the human body is to generate heat, which is less harmful.
Fluorescent computer screens use cathode ray tubes, which can also produce x-rays, but LCD screens do not produce x-rays.
What are the energy sources which have nothing to do with solar radiation?
The generators have completely closed outer pots, and the magnetic field and coThe current they generate is in their closed shell. At the same time, for the low frequency of 50 Hz, the radiation generated outside the body is very weak. It took almost two hundred years from the invention of communication to its current use. There are countless studies and reports on alternating radiation-related illnesses among workers at power plants, substations, and switching stations. The radiation of alternating current is much weaker than that of sunlight, light bulbs, fires, etc. to which we are exposed.
Types of energy that are not related to solar radiation are:
1 Fossil fuels: Fossil fuels are the energy produced. by organisms inside the earth for millions of years. Formed by the compression and decomposition of coal, oil and natural gas. The generation ofThese energy sources are independent of solar radiation because they are not directly converted from solar energy.
2. Nuclear Energy: Nuclear energy is produced using the energy released during the fission or fusion of atomic nuclei. Although solar energy comes from nuclear fusion, nuclear energy on Earth does not directly depend on solar radiation. Radioactive isotopes on Earth can release nuclear energy on their own, and this energy has been used in areas such as power generation and scientific research.
3. Hydropower: Hydraulic power is energy generated by the use of water resources such as currents, water levels, or tides. The production of this energy has nothing to do with solar energy, but relies on the gravitational potential energy of the Earth and the movement of water.
4. Wind power :Wind power is energy generated by using wind energy to operate wind turbines (wind generators). Although the formation of wind is affected to a certain extent by solar energy, wind energy is not directly converted from solar energy, but is a manifestation of the thermodynamic process of solar energy in the Earth's atmosphere.
The main dangers of solar radiation:
1. Skin Cancer: The most direct harm of excessive sunlight to the skin is causing skin cancer. Long-term exposure to strong sunlight can cause skin cells to mutate, leading to skin cancer. Skin cancer is a common malignancy with a high incidence rate worldwide.
2. Eye Damage: The damage caused to the eyes by excessive solar radiation cannot be ignored. The strong light of theSun can damage the cornea and retina, causing visual problems such as snow blindness. Prolonged exposure to the sun can also increase the risk of eye diseases such as cataracts.
3. Climate Change: Solar radiation also impacts the Earth's climate and environment.Significant influence. Increased solar radiation can cause the Earth's temperature to increase, triggering climate changes such as global warming. Global warming will lead to rising sea levels and an increase in extreme weather events, which will have widespread impacts and damages on human society and the natural environment.
