Kurzwellenstrahlung
Kurzwellenstrahlung refers to electromagnetic radiation with wavelengths shorter than those of visible light and longer than those of X-rays. This range of the electromagnetic spectrum encompasses ultraviolet (UV) radiation. UV radiation is produced by the sun and by artificial sources like tanning beds and germicidal lamps. It is typically divided into three sub-bands: UVA, UVB, and UVC, based on wavelength. UVA, with the longest wavelength, penetrates the skin most deeply and contributes to skin aging. UVB, with a shorter wavelength, is responsible for sunburn and plays a crucial role in the synthesis of vitamin D in the skin. UVC, with the shortest wavelength, is the most energetic and potentially damaging form of UV radiation, but it is largely absorbed by the Earth's ozone layer and therefore does not reach the surface in significant amounts. Exposure to excessive UV radiation, particularly UVB, can lead to skin cancer, premature aging of the skin, and eye damage such as cataracts. However, controlled exposure to UV radiation has therapeutic applications in medicine, such as for treating certain skin conditions like psoriasis and eczema, and its role in vitamin D production is essential for bone health.
