Exposure to ultraviolet (UV) radiation is a risk factor for skin cancer and other diseases. The risk increases when sunlight, the natural source of UV radiation, is combined with artificial sources such as UV lamps for medical therapy, among others. Detecting and measuring UV exposure in different environments was the scope of a research project conducted in Brazil at the São Paulo Federal Institute of Education, Science and Technology (IFSP) in collaboration with the University of São Paulo Physics Institute (IF-USP).
