Power adapter manufacturers believe that radiation is a hidden pollution, but all the time affect our health. Many people have certain concerns about the radiation of the power adapter, although the power adapter will sometimes be hot, and is directly connected to the 220V grid, but this heat is thermal radiation, rather than electromagnetic radiation generated by heat. And now a lot of high quality power adapter internal use of good radiation isolation measures, so that basically will not produce the so-called radiation.
The essence of electromagnetic radiation is the change in the electric field of space causes particles to radiate protons. Although electromagnetic radiation has always existed, but in the last 100 years mankind only discovered, before mankind only know the existence of electromagnetic induction phenomenon, but did not think in the process of this induction phenomenon will still be excited and radiated energy.
Electromagnetic radiation is not harmful to the human body, which is the same as voltage will not be harmful to the human body, but the current generated will hurt people, radiation is only a fluctuation. But this fluctuation will cause some physical particles to react when passing through the body or air.
Now consider the nature of this reaction. How does the energy field lead to the generation of positive charge? In fact, too much energy leads to the imbalance of positive charge inside the particle, because the positive point is too much so that there will be a part of the charge overflow, which is the proton. Once the proton is overflowing, it has its own electrical energy, and the previous material is to become a radiator. The excitation of this electromagnetic wave requires a certain amount of energy to assist.
Digital circuitry is the killer of radiation generation. Many digital points are related to the clock signal, this signal exists a certain fluctuation, for example, when using the computer CPU main frequency is actually a symbolic reflection. Digital circuits work in the clock state back and forth from the oscillation of electromagnetic radiation is inevitable. This is also similar to cell phones or desktop computers will produce radiation reasons. Power adapter generated by the radiation is mostly circuit thermal radiation, this radiation is now also can be felt, for example, near the stove people are able to feel the heat. And this radiation is harmless to the human body.
From the above we can see that the power adapter does not produce radiation to the human body, but power adapter manufacturers warmly remind: pregnant women and children in life or to avoid reducing contact time with power adapters, chargers and other electronic products.
