OBJECTIVE This pilot study aimed to estimate annual occupational ultraviolet radiation (UVR) exposures based on 5 consecutive months of dosimetry measurements in Croatian construction workers and assess its relationship with the environmental data collected during the same period. METHODS Four male construction industry workers from the vicinity of Zagreb (lat. 45.8° N, alt. 128 m) participated in the study. The study was a part of the GENESIS-UV project, attempting to collect long-term dosimetry data for outdoor occupations across Europe. Workers wore personal dosimeters (model X2012-10, Gigahertz, Tuerkenfeld, Germany) on the left upper arm during working hours in the period from June to October 2017. Median exposure assessment period was 57 working days. RESULTS Estimates of annual occupational UVR exposure ranged from 76 SED to 976 SED per worker, reflecting large differences in patterns of workers' exposure. Daily UVR doses received by the workers were comparable to the values of other studies at similar latitudes, reaching up to 12 SED in summer months. Measurements of workers with high exposure values (estimated >600 SED/year) showed moderate to high associations with environmental UVR and insolation data (Spearman's correlation coefficient ranging from 0.57 to 0.73). CONCLUSIONS The results confirmed high occupational exposure of tested Croatian construction workers to solar UVR. However, more data are needed to explain the between-worker variability and develop prediction models with respect to specific work tasks. The use of environmental UVR for predicting long-term exposure should be considered, especially for high exposure tasks.

个人紫外线辐射剂量学及其与环境数据的关系：克罗地亚建筑工人的纵向试验研究。

目的这项初步研究旨在基于克罗地亚建筑工人连续5个月的剂量学测量估算年度职业紫外线辐射（UVR）暴露，并评估其与同期收集的环境数据之间的关系。方法来自萨格勒布（纬度45.8°N，高度128 m）附近的四名男性建筑业工人参加了研究。这项研究是GENESIS-UV项目的一部分，旨在收集整个欧洲户外职业的长期剂量数据。在2017年6月至2017年10月的工作时间内，工人在左上臂佩戴了个人剂量计（型号X2012-10，Gigahertz，德国图肯费尔德）。中位暴露评估期为57个工作日。结果每年每名工人的职业UVR暴露估计在76 SED到976 SED之间，反映了工人暴露方式的巨大差异。工人每天接受的UVR剂量与纬度相似的其他研究的值相当，在夏季达到12 SED。对具有高暴露值（估计> 600 SED /年）的工人进行的测量显示，与环境UVR和日照数据的关联度为中度至高度关联（Spearman的相关系数范围为0.57至0.73）。结论该结果证实了受测试的克罗地亚建筑工人在高强度紫外线照射下的职业暴露。但是，需要更多的数据来解释工人之间的差异并针对特定的工作任务开发预测模型。
