职场暴露于太阳紫外线（UV）会引起恶性黑色素瘤和非黑色素瘤皮肤癌。有关太阳紫外线暴露对于降低其他癌症风险的有益影响的证据正在增加。地球表面的紫外线辐射强度取决于纬度，但即使在北欧国家，户外工作引起皮肤癌的紫外线暴露也可能足够高。对于职业性太阳紫外线暴露的健康风险和益处的认识很差。已经确定了减少皮肤癌风险的行动，雇主应该认识到他们有责任积极管理这些风险。有证据表明，太阳紫外线暴露与乳腺癌、卵巢癌和结肠直肠癌等癌症的风险降低有关。本综述文章依据已发表的科学文章和旨在辅助识别保护工人免受太阳紫外线暴露的策略的材料。太阳紫外线暴露可能会有害。紫外线B波段的波长更有效地引起红斑和DNA损伤。太阳紫外线是大多数人维生素D的主要来源。皮肤癌的初级和二级预防有可能消除这些风险，但有效性证据有限。太阳紫外线暴露的潜在健康益处，特别是降低癌症风险。确定并传达最佳暴露以最大化健康益处。在温和纬度一些工人的非黑色素瘤皮肤癌的风险可能会增加一倍以上。暴露-反应流行病学研究；职业暴露于紫外线的健康益处研究；干预策略防止皮肤癌效果研究。在工作场所使用低成本紫外线传感器。©作者（们）2022年出版，牛津大学出版社发行。

Workplace exposure to solar ultraviolet (UV) causes malignant melanoma and non-melanoma skin cancer. The evidence for beneficial effects of solar UV exposure in reducing the risks for other cancers is increasing. The intensity of UV radiation at the Earth's surface is dependent on latitude, but even in northern European countries exposure can be high enough for outdoor work to cause skin cancer.Awareness of the health risks and benefits of occupational solar UV exposure is poor. Actions to reduce the risk of skin cancer have been identified and employers should recognize their responsibility to actively manage these risks. There is evidence for reduced risks for breast, ovarian and colorectal cancer and possibly other cancers linked to solar UV exposure.This narrative review draws on published scientific articles and material designed to assist identifying strategies to protect workers from solar UV exposure.Solar UV exposure can be harmful. Wavelengths in the UVB range are more effective in causing erythema and DNA damage. Solar UV is the main source of vitamin D for most people. Primary and secondary prevention for skin cancer can potentially eliminate these risks but the evidence for effectiveness is limited.Potential health benefits of UV exposure, particularly for reduced cancer risk. Determining and communicating optimal exposure to maximize health benefits. The risk of non-melanoma skin cancers may be more than doubled for some workers in temperate latitudes.Exposure-response epidemiological studies; studies of the health benefits of occupational UV exposure; studies of the effectiveness of intervention strategies to prevent skin cancer.
