The erythemal ultraviolet exposure for humans in greenhouses.
A spectrum evaluator has been employed to evaluate the erythemal exposure in late spring and late summer at three sites and five orientations at each site inside a glass greenhouse with black shadecloth over the glass roof. The maximum in the erythemal irradiance in the greenhouse is not necessarily at noon. Over a day, the maximum erythemal exposure occurred on the eastern side of the greenhou...
متن کاملSpatiotemporal exposure modeling of ambient erythemal ultraviolet radiation
BACKGROUND Ultraviolet B (UV-B) radiation plays a multifaceted role in human health, inducing DNA damage and representing the primary source of vitamin D for most humans; however, current U.S. UV exposure models are limited in spatial, temporal, and/or spectral resolution. Area-to-point (ATP) residual kriging is a geostatistical method that can be used to create a spatiotemporal exposure model ...
متن کاملThe facial distribution of erythemal ultraviolet exposure in south-east Queensland.
This paper presents a method for the evaluation of the distribution of the facial erythemal UV exposure and the erythemal UV exposure per unit area of the face using only eight dosimeters located on the vertex of the head, forehead, nose, chin, left and right ears and left and right cheeks. An overall picture of the parts of the face receiving high UV exposures is provided. The distribution of ...
متن کاملQuantitative evaluation of the personal erythemal ultraviolet exposure in a car.
Erythemal ultraviolet (UV)-radiation exposure to the right hand, mid-arm, shoulder, chin, nose and left and right sides of the face has been evaluated in a car from a large family class and a car from a small car class. In the small car, the site with highest exposure received 2.2 times more radiation than the site with the highest exposure in the larger car. In both cars, highest erythemal exp...
متن کاملErythemal irradiances of filtered ultraviolet radiation.
A spectrum evaluator (3 cm x 3 cm) employing four passive dosimeters has been used to evaluate the time averaged spectrum to allow calculation of the erythemal exposures resulting from the predominantly UVA component of filtered solar ultraviolet radiation. An exposure interval of approximately 20 min to autumn and spring sunshine was required for the spectrum evaluator to allow evaluation of t...
