Ocular Damage by Environmental Radiant Energy and Its Prevention,. The cornea absorbs ultraviolet energy of wavelengths shorter than 300 nm and can be damaged by it (photokeratitis). Another target of UV damage is the DNA in the nuclei of corneal epithelial cells. Repair of the DNA is quite rapid, however, as is the replacement of damaged cells (Pitts ., 1986). U

Ultraviolet Radiation and Skin Cancer: Epidemiological Data from Australia,nal Australians are rarely affected by skin cancer. From first settlement until the midtwentieth century, inhabitants of Australia were almost entirely of British descent, with high proportions of Irish and Scots. Their migration and settlement signified a shift from northern latitudes of 51 ° to 59

Ultraviolet Radiation and Skin Cancer: Epidemiological Data from Scandinavia,x, 1982). Scandinavia is located at high latitudes (>54°N) and therefore receives relatively small annual exposures of ultraviolet (UV) radiation from the sun. In spite of this, skin cancer (cutaneous malignant melanoma, squamous cell carcinoma, and basal cell carcinoma) is more frequent than any ot

Ultraviolet Radiation and Skin Cancer: Epidemiological Data from the United States and Canada,th America, and each has therefore been the subject of numerous investigations. This chapter reviews the descriptive and analytic epidemiology of melanoma and nonmelanoma skin cancer. The data reviewed are based primarily on populations in the United States and Canada; the (largely parallel) results

Ultraviolet Radiation and Its Effects on Organisms in Aquatic Environments,the impact of UVR on terrestrial plants. The major reasons for this are that spectral irradiance changes dramatically with depth in the water column and that most aquatic organisms will be moving up and down in the upper water column, either through active motility processes or by physical mixing pr

Effects of Ultraviolet-B Radiation on Terrestrial Plants, a result of scattering, internal reflection, and absorption, none of which occurs in a uniform way. Methods which have been employed to estimate the penetration of radiation into plant tissues have included theoretical calculations, measurements of whole leaf or epidermal reflectance and absorptanc
