UVBsäteily

UVB radiation, also known as medium-frequency ultraviolet radiation, is a type of ultraviolet light emitted by the sun and artificial sources like tanning beds. It has a wavelength range of approximately 280 to 315 nanometers. UVB rays are a significant contributor to sunburn and are also known to play a role in the development of skin cancer. However, UVB is essential for the skin's production of vitamin D, a vital nutrient for bone health and immune function. The Earth's ozone layer absorbs a substantial portion of UVB radiation, protecting life on the surface. Factors such as the time of day, season, latitude, and altitude influence the intensity of UVB exposure. High altitudes and tropical regions generally experience higher levels of UVB. Protective measures against excessive UVB exposure include the use of sunscreen, protective clothing, and seeking shade, especially during peak sunlight hours.
