Human Exposure to Filtered Solar Ultraviolet Radiation
The erythemal exposure due to filtered ultraviolet radiation has been evaluated with a dosimetric spectrum evaluator in a glass enclosure to simulate a sun-room with glass roof and walls, in a greenhouse and in a small and large car. The ratio expressed as a percent of the erythemal irradiances to the shoulder of a person in an upright position inside each of the environments to those measured ...
متن کاملVascular endothelial growth factor promotes sensitivity to ultraviolet B-induced cutaneous photodamage.
Acute ultraviolet B (UVB) irradiation of the skin results in erythema, vasodilation, edema, and angiogenesis, which is associated with the expression of vascular endothelial growth factor (VEGF) by epidermal keratinocytes. It is unclear, however, whether VEGF is required for the damage or repair process that occurs in the skin on UVB exposure. We subjected transgenic mice that overexpress VEGF,...
متن کاملOutdoor Exposure to Solar Ultraviolet Radiation and Legislation in Brazil.
The total ozone column of 265 ± 11 Dobson Units in the tropical-equatorial zones and 283 ± 16 Dobson Units in the subtropics of Brazil are among the lowest on Earth, and as a result, the prevalence of skin cancer due to solar ultraviolet radiation is among the highest. Daily erythemal doses in Brazil can be over 7,500 J m. Erythemal dose rates on cloudless days of winter and summer are typicall...
متن کاملAssociation between cutaneous melanoma incidence rates among white US residents and county-level estimates of solar ultraviolet exposure.
BACKGROUND Recent US studies have raised questions as to whether geographic differences in cutaneous melanoma incidence rates are associated with differences in solar ultraviolet (UV) exposure. OBJECTIVES We sought to assess the association of solar UV exposure with melanoma incidence rates among US non-Hispanic whites. METHODS We assessed the association between county-level estimates of a...
متن کاملPatterns in Surface Distribution of Human Exposure to Solar Ultraviolet
A method for the three dimensional representation of erythemally effective ultraviolet radiation (UVery) incident to the human body has been developed from a series of polysulphone dosimeter (PS) measurements to the face, neck, arms, legs and hands of a manikin model. The technique has been used to represent a series of human UVery exposure patterns in the solar zenith angle (SZA) range 30-50 m...
