UVA, UVB, UVC
From Domicella's wikiStyle
The sun gives off ultraviolet (UV) radiation that we divide into categories based on the wavelength. UVC radiation is absorbed by the atmosphere and does not cause skin damage. UVB radiation affects the outer layer of skin, the epidermis, and is the primary agent responsible for sunburns. UVB does not penetrate glass, and the intensity of UVB radiation depends on the time of day and the season. UVA radiation penetrates deeper into the skin and works more efficiently. The intensity of UVA radiation is more constant than UVB without the variations during the day and throughout the year. UVA is also not filtered by glass. [1]
UVB rays cause sunburn and skin cancer; UVA rays cause aging and likely skin cancer.[2]
Stay out of the midday sun (from 10 in the morning to 4 in the afternoon), which is the strongest sunlight.[2]
