Adverse effects of ultraviolet radiation: A brief review

Abstract

Solar ultraviolet radiation (UVR) has always been part of the environment of man. UVB is required for the conversion of 7-deoxycholesterol to vitamin D, which is critically important in the maintenance of healthy bones and research is making clear that it has other potential roles in maintenance of human health. Exposure to UVR, whether of solar or artificial origin, also carries potential risks to human health. UVR is a known carcinogen and excessive exposure-at least to solar radiation in sunlight-increases risk of cancer of the lip, basal cell, and squamous cell carcinoma of the skin and cutaneous melanoma, particularly in fair skin populations. There is also evidence that solar UVR increases risk of several diseases of the eye, including cortical cataract, some conjunctival neoplasms, and perhaps ocular melanoma. Solar UVR may also be involved in autoimmune and viral diseases although more research is needed in these areas. Artificial UVR from tanning beds, welding torches, and other sources, may contribute to the burden of disease from UVR. This brief review will assess the human evidence for adverse health effects from solar and artificial UVR and will attempt to assign a degree of certainty to the major disease-exposure relationships based on the weight of available scientific evidence.

Comportamento relativo à exposição e proteção solar na população de 15 anos ou mais de 15 capitais brasileiras e Distrito Federal, 2002-2003

“…Vários estudos relacionam a exposição à radiação solar como uma das principais causas de câncer de pele tipo melanoma e não melanoma 1 . Particularmente no Brasil, dentre todas as localizações, o câncer de pele não melanoma é o mais freqüente, apresentando taxas brutas de incidên-cia estimadas, para o ano de 2006, de 68,1 e 68,9 por 100 mil entre homens e mulheres, respectivamente 2 .…”

Paparan Ultraviolet C Meningkatkan Diameter Pulpa Alba Limpa dan Indeks Mitotik Epidermis Kulit Mencit

“…Hewan uji yang digunakan adalah mencit galur Balb/C, betina, berjumlah Fenomena global warming yang berdampak pada 25 ekor, umur 2 bulan dan berat badan 20-30g. penipisan lapisan ozon di bumi dapat menyebabkan radiasi UV C sampai ke permukaan bumi dan berakibat Mencit dibagi menjadi 5 kelompok yaitu kontrol tanpa buruk terhadap makhluk hidup (4). Sinar UV C adalah sinar perlakuan dan empat kelompok perlakuan dengan dengan energi tertinggi, paling berbahaya diantara sinar pemaparan sinar ultraviolet C intensitas 15 menit (P1), 30 ultraviolet lainnya.…”

Influence of reflected UV irradiance on occupational exposure from combinations of reflective wall surfaces

“…[1][2][3][4] Conversely it can be detrimental in excessive quantities through an increased induction of erythema (sunburn), non-melanoma and melanoma skin cancer, ocular damage, DNA damage 5 and is linked to immunosuppression and photo aging. 6 Populations of UV sensitive people are generally at risk from damage due to UV radiation when living in areas of high ambient UV radiation, however that risk is increased in members of the population who occupationally spend working hours exposed to solar UV radiation [7][8][9] depending on skin type and individual factors.…”
