Explanation:
Detailed explanation-1: -UVB rays have slightly more energy than UVA rays. They can damage the DNA in skin cells directly, and are the main rays that cause sunburns.
Detailed explanation-2: -Skin cancers are caused primarily by exposure to ultraviolet radiation (UVR), either from the sun or from artificial sources such as sunbeds.
Detailed explanation-3: -Indoor tanning equipment (e.g., beds, booths and lamps) emit ultraviolet (UV) radiation. Like UV radiation in sunlight, a tanning bed’s UV stimulates the skin to release a pigment called melanin. Melanin absorbs the UV, causing the skin to darken.
