Exposure to UV Radiation in Lifeguards on Barcelona's Beaches: An Underestimated Occupational Risk

Abstract

BackgroundThe development of skin cancer is closely related to high exposure to UV radiation. Lifeguards are at an increased risk of excessive sun exposure. ObjectivesThe main objective of this study was to measure the exposure of Barcelona's beach lifeguards to UV radiation. MethodsMeasurements in the work chair were taken every 30min on a typical working day from 10:45 am to 19:15 pm. These measurements were carried out on four different days. These data were used to calculate the erythematous doses received during working hours, as well as those potentially received throughout the summer season. Vitamin D production was also estimated for the four days that the radiation received was measured, and the amount generated was calculated for the entire summer season. ResultsExposure to UV radiation among Barcelona lifeguards far exceeds safety limits. In some locations, the exposure to UVB radiation is more than 16 times the minimum erythematous dose for phototype II skin. LimitationsThis study assessed the radiation received during only four days. However, is a much higher number than most of the published papers. ConclusionAlthough the health risks of excessive exposure to UV radiation are known, Barcelona's beach lifeguards are insufficiently protected.
