Ultraviolet Radiation

Ultraviolet (UV) radiation is a type of electromagnetic radiation that comes from the sun and various artificial sources, such as tanning beds and black lights. It has a shorter wavelength and higher energy than visible light and is divided into three main types: UVA, UVB, and UVC.

Effects of Ultraviolet Radiation

UV radiation can have both positive and negative effects on living organisms. For example, it plays a crucial role in the production of vitamin D in the skin, but overexposure to UV radiation can lead to sunburn, premature aging of the skin, and an increased risk of skin cancer.

Protection from Ultraviolet Radiation

There are several measures that can be taken to protect oneself from the harmful effects of UV radiation, such as using sunscreen with a high SPF, wearing protective clothing, and seeking shade during peak sun hours.
