Emette raggi UV-A e a tal proposito:
There are 3 types of UV rays:
UVA: A stands for Aging.
UVA radiation penetrates deep into the skin and is responsible for
premature aging of the skin and skin cancer. Tanning beds can emit 2 to 5 times more UVA radiation than the sun.
UVB: B stands for Burning.
UVB radiation is stronger than UVA radiation. It mainly affects the outer layers of the skin, causing sunburns, premature aging of the skin, and skin cancer. These rays are strongest during the summer months – especially between 11 am and 4 pm.
UVC: UVC radiation is the strongest, most dangerous form of UV light. However, they are stopped by the earth’s atmosphere and do not reach earth’s surface.
