Where does the radiation come from? Electricity machinery have radiation,

Electromagnetic waves and radioactive substances produced by the radiation, due to their different energies, according to the material atoms or molecules can be directly or indirectly caused by the ionizing effect and will be divided into two major types of ionizing radiation and non-ionizing radiation. Radioactive decay of particles such as alpha particles, beta particles, X-rays, R-rays and neutrons belong to ionizing radiation, ultraviolet radiation, infrared radiation, radiofrequency electromagnetic fields and microwaves belong to non-ionizing radiation. Radiation is everywhere! Household appliances: television, refrigerator, air conditioning, microwave ovens, vacuum cleaners, computers, etc. Office equipment: cell phones, computers, copiers, electronic instruments, medical equipment, etc. Home decoration: marble, composite flooring, wallpaper, paint, etc. Surrounding environment: high-voltage lines, power substations, television (radio) signal transmission towers, etc. Natural environment: sunspots, etc.
