Solar ultraviolet radiation: properties, characteristics and amounts observed in Brazil and South America.

Abstract in brief

• This article discusses the dual nature of solar UV radiation, highlighting its beneficial role in vitamin D production and its harmful effects like skin cancer, especially in Brazil where local data is scarce.
• It emphasizes the importance of understanding UV properties specific to Brazil and South America, as they differ significantly from European and American data, which can influence protective measures.
• The article provides detailed, accessible information on UV radiation and UV index, summarizes recent regional measurements, and compares them internationally to improve awareness and health risk assessments related to sun exposure.]
