Commonly used power adapter to the body will produce radiation
- Oct 20, 2017 -

Radiation is a kind of invisible pollution, but it affects our health all the time. Many people have some concerns for the radiation problem of the power adapter, although power adapter will be fever sometimes, and direct access in the power grid of 220V, but the heat is not heat radiation, electromagnetic radiation generated by heat. And now a lot of high quality power adapter internal use of good radiation isolation measures, so basically won't produce so-called radiation.

The essence of electromagnetic radiation is that the change of space electric field leads to particles emit protons

Although the electromagnetic radiation has always been there, but in the last 100 years, the human is found before humans only know the existence of the phenomenon of electromagnetic induction, but did not think in the process of the induction in the material will be excited and emit energy. Electromagnetic radiation is not harmful to the human body, that is, and the voltage does not harm the human body, but the current generated by it will hurt people, radiation is just a kind of fluctuation. But this fluctuation causes physical particles to react when they pass through the body or the air. present

Think about the nature of this reaction.

How the energy field leads to the generation of positive charges is, in fact, excessive energy leading to the imbalance of the positive charge inside the particles, because it is too much, so there is a part of the charge overflow, which is the proton. Once the proton is out of circulation, it itself is equipped with electrical energy, and the former material is become a radiation. The excitation of this electromagnetic wave requires a certain amount of energy.

Digital circuits are the killers of radiation

A lot of digital points are related to clock signals, and there is a certain fluctuation in this signal, for example, the main frequency of CPU is actually a symbolic reflection when using a computer.  Digital circuit work in the clock state back to the concussion, the electromagnetic radiation is inevitable. It's also the cause of the radiation that happens on a cell phone or desktop computer.

The radiation generated by the charger is mostly thermal radiation of the circuit

The radiation generated by the charger is often the thermal radiation of the circuit, and this radiation can also be felt now, for example, people close to the stove can feel the heat. And this radiation is harmless to the human body.
