Solar radiation means that the sun transmits energy outward in the form of electromagnetic waves, and the sun emits electromagnetic waves and particle streams into space. The energy transmitted by solar radiation is called solar radiation energy.
Although the solar radiation energy received by the earth is only one-twentieth of the total radiation energy radiated by the sun to the universe, it is the main energy source of the earth's atmospheric movement and the main source of the earth's light and heat energy. On October 27, 2017, the list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization was initially collated and referenced, and solar radiation was included in the list of carcinogens of the first category.
