Analysis of Erythemal UVB Dose Received Inside a Car in Valencia, Spain

Continuous exposures to ultraviolet radiation can lead to harmful effects on human skin. Professional drivers may spend more than 8h per day inside a vehicle. This study describes an analysis of the UVER (erythemal ultraviolet radiation) received by a driver and passenger inside a vehicle. A three-door Peugeot 206 was used for the study. VioSpor Blue Line dosimeters (with a response profile close to that of human skin) were used to measure the erythematic dose of UV radiation (able to produce erythema on human skin). Four dosimeters were placed in the driver's position and another four in the passenger's position. Daily irradiance was analyzed for a day in April using PMA radiometers. The measurements were obtained on relatively clear days from February to December 2009 between 9:30 A.M. and 3 P.M. Additionally, a prediction was made of the time required to produce an erythema on the driver's skin. UVER exposure, in some of the driver's positions, exceeds the Exposure Limits given by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). Skin protection measures should be taken into account by professional drivers to prevent the harmful effects of UVER radiation.
