Ultraviolet (UV) radiation is an invisible form of light that is part of the electromagnetic spectrum. It is naturally emitted from the sun and is also found in artificial sources such as tanning beds and welding torches. UV radiation is divided into three categories based on wavelength: UV-A, UV-B, and UV-C. Of these, UV-A has the longest wavelength and is the least harmful, while UV-C has the shortest wavelength and is the most harmful (Ahrens, 2019).

The primary health concern associated with UV radiation is skin cancer. UV radiation damages the DNA in skin cells, which can lead to the development of skin cancer. It can also cause sunburns, premature aging, and eye damage (Korner et al., 2020). To reduce the risk of these adverse effects, individuals should limit their exposure to UV radiation by seeking shade, wearing protective clothing, and using sunscreen (Goh & Lim, 2020).

UV radiation is also used for a variety of beneficial purposes. For example, it can be used to disinfect drinking water and surfaces, kill bacteria, and produce Vitamin D in the body (Chamoli, Shrivastava, & Singh, 2019). Additionally, UV radiation is used in phototherapy to treat a variety of conditions, such as psoriasis, acne, and eczema (Carrington, 2019).

In conclusion, UV radiation can be both harmful and beneficial. Individuals should take precautions to limit their exposure to UV radiation to reduce the risk of skin cancer and other adverse health effects. However, UV radiation can also be used for a variety of beneficial purposes, such as phototherapy and disinfection.
