Measurement of UVA exposure to solar radiation.
Exposure to solar UVA (320-400 nm) radiation can damage DNA and lead to skin disorders. Conventional dosimetry using a single piece of polysulfone or diglycol carbonate (CR-39) cannot provide accurate measurement of the biologically effective irradiance for erythema for the UVA waveband. A package employing four dosimeters (polysulfone, nalidixic acid, 8-methoxypsoralen and phenothiazine) has b...
متن کاملHuman 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 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 کاملImpact of climate change on occupational exposure to solar radiation.
Occupational exposure to solar radiation may induce both acute and long-term effects on skin and eyes. Personal exposure is very difficult to assess accurately, as it depends on environmental, organisational and individual factors. The ongoing climate change interacting with stratospheric ozone dynamics may affect occupational exposure to solar radiation. In addition, tropospheric levels of env...
متن کاملDrinking Water Disinfection by Solar Radiation
A primary concern of developing countries throughout the world is that of obtaining safe drinking water. Waterborne diseases are still common in developing countries since drinking water sources are contaminated and the conventional rural water treatment plants are often inefficient to produce safe drinking water. This situation in developing countries is a major problem in terms of preventing ...
