[45] [failed verification] UVC is the highest-energy, most-dangerous type of ultraviolet radiation, and causes adverse effects that can variously be mutagenic or carcinogenic. [46] Despite the importance of the sun to vitamin D synthesis, it is prudent to limit the exposure of skin to UV radiation from sunlight [47] and from tanning beds. [48]
Prolonged exposure to ultraviolet radiation from the sun can lead to melanoma and other skin malignancies. [4] Clear evidence establishes ultraviolet radiation, especially the non-ionizing medium wave UVB, as the cause of most non-melanoma skin cancers, which are the most common forms of cancer in the world.

The location of 'far-UVC' radiation (200-235 nm) in the electromagnetic spectrum. Far-UVC is a type of ultraviolet germicidal irradiation being studied and commercially developed for its combination of pathogen inactivation properties and reduced negative effects on human health when used within exposure guidelines. [1] [2] [3] [4]
Phytophotodermatitis may be aggravated by the additional levels of ultraviolet light emitted by compact fluorescent light. Patients undergoing photodynamic therapy are at additional risk of adverse photosensitive reactions caused by compact fluorescent light. One cause of cataracts is exposure to ultraviolet light. Provided the level of UV ...
Actinic keratosis (AK), sometimes called solar keratosis or senile keratosis, [1] [2] is a pre-cancerous [3] area of thick, scaly, or crusty skin. [4] [5] Actinic keratosis is a disorder of epidermal keratinocytes that is induced by ultraviolet (UV) light exposure ().
A radiation burn is a damage to the skin or other biological tissue and organs as an effect of radiation. The radiation types of greatest concern are thermal radiation, radio frequency energy, ultraviolet light and ionizing radiation. The most common type of radiation burn is a sunburn caused by UV radiation.
Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [1] Symptoms can start within an hour of exposure, and can last for several months.
Photodermatoses is a skin condition resulting in abnormal skin reactions to ultraviolet (UV) radiation. [1] These abnormal skin reactions may develop into rashes. While reactions to UV radiation is common, true photodermatoses is considered when an abnormal reaction is caused by UV-A rays or radiation between 320 and 400 nm.
