Is there a radiation inside the substation? The secondary substation equipment is mechanical, but now all the integrated circuits, plus several computers? Solution
Radiation this concept is too broad, in broad terms, all the electromagnetic waves can be classified as electromagnetic radiation, such as sunlight, cell phone signals and so can be called radiation, since the human began to use electromagnetic communication since the electromagnetic radiation began to increase in nature, The subject of the place must have a radiation.
As far as the impact on health depends on the energy density of radiation, the radiation of the integrated circuit (unless it is specifically used to transmit the signal) is almost negligible because a very important principle in circuit design is to do electromagnetic compatibility and avoid mutual interference ; Especially in the design of high-frequency circuit is even more so, otherwise the circuit is prone to clutter and space parasitic loop, so that the device function is affected.
Buy some electrical basis and power transmission technology books to see.
In fact, to achieve the extent of the impact on the human body, the radiation source power needs to reach a large value can be, to achieve this level is probably only some high-power radar and other antenna equipment. And the attenuation of electromagnetic radiation and frequency, the daily power system frequency 50Hz is a very low frequency, the propagation range is also very small.
In addition, many media intentionally or unintentionally confuse the difference between electromagnetic radiation and nuclear radiation (presumably a common problem for the layman, and of course there are some senseless and unspeakable writers). The carrier of nuclear radiation is mainly matter particles (such as α particles, high-speed electrons, neutrons) and high-energy electromagnetic waves (γ-ray), the electromagnetic radiation carrier is electromagnetic waves, the energy density of the two can not be made, for example, Radiation is equivalent to out of the shells, and electromagnetic radiation is equivalent to easily throw out the paper group, the destructive power is clearly different, of course, the impact on human health is also very different.
