Radiation, some radioactive elements will emit strong rays, such as iridium ~ plutonium and so on. , can cause genetic variation and abnormal proliferation in human body, such as cancer.
Electromagnetic radiation is that the electric field and magnetic field oscillate in the same direction and are perpendicular to each other. It transmits momentum and energy in space in the form of waves, and its propagation direction is perpendicular to the plane formed by the electric field and magnetic field. The interaction between electric field and magnetic field produces electromagnetic waves, which are emitted or propagated into the air to form electromagnetic radiation. Electromagnetic radiation consists of electric energy and magnetic energy which are jointly transmitted in space, and this energy is generated by the movement of electric charges. For example, moving charges from a radio frequency antenna transmitting signals will generate electromagnetic energy. The electromagnetic "spectrum" includes all kinds of electromagnetic radiation, from extremely low frequency electromagnetic radiation to extremely high frequency electromagnetic radiation. There are also radio waves, microwaves, infrared rays, visible light and ultraviolet rays between them. The radio frequency part of the electromagnetic spectrum is generally defined as radiation with a frequency of about 3 khz to 300 GHz. Some electromagnetic radiation has certain influence on human body.
