Power adapter manufacturers believe that radiation is a hidden pollution, but all the time is not affecting our health. A lot of people have some concerns about the radiation of the power adapter, although the power adapter will sometimes be hot, and is directly connected to the 220V power grid, but this heat is thermal radiation, rather than electromagnetic radiation generated by heat. Nowadays, many high-quality power adapters use good radiation isolation measures, so basically does not produce the so-called radiation.
The essence of electromagnetic radiation is that changes in the electric field in space cause particles to radiate protons. Electromagnetic radiation has always existed, but in the last 100 years mankind is only found, before mankind only know that there is electromagnetic induction phenomenon, but did not think that in this induction phenomenon occurs in the process of material will still be excited and radiate energy. Electromagnetic radiation is not harmful to the human body, that is, and the voltage will not be harmful to the human body, but the current generated by the same will hurt people, radiation is only a kind of fluctuation. Radiation is merely a fluctuation, but this fluctuation causes physical particles to react when it passes through the body or the air.
Now consider the nature of this reaction. How the energy field leads to a positive charge is that too much energy causes an imbalance in the positive charge inside the particle, and because there are too many positive points, there is a partial spillover of the charge, which is the proton. Once the proton is overflow, its own is with the electrical energy, and the former material is to become a radioactive material. The excitation of this electromagnetic wave requires a certain amount of energy.
Digital circuits are the murderers who produce radiation. Many digital points are related to the clock signal, there are certain fluctuations in this signal, such as the use of computers when the main frequency of the CPU is actually a symbolic reflection. Digital circuits work in the clock state back and forth oscillation generates electromagnetic radiation is inevitable. This is also similar to cell phones or desktop computers will produce radiation. Power adapter radiation generated by the circuit thermal radiation, this radiation can now be felt, for example, near the stove is to feel the heat. And this radiation is harmless to the human body.
From the above content can be seen power adapter does not produce radiation on the human body, but the power adapter manufacturer warmly reminds: pregnant women and children in life or to avoid reducing the contact time with power adapters, chargers and other electronic products.
