Exposure to solar ultraviolet (UV) radiation is the main causative factor for skin cancer. Outdoor workers are at particular risk because they spend long working hours outside, may have little shade available and are bound to take their lunch at their workplace. Despite epidemiological evidence of a doubling in risk of squamous cell carcinoma (SCC) in outdoor workers, the recognition of skin cancer as an occupational disease remains scarce.
To assess occupational solar UV doses and their contribution to skin cancer risk.
A numerical model (SimUVEx) was used to assess occupational and lunch break UV exposure, and to characterize exposure patterns and anatomical distribution. Risk of SCC was estimated from an existing epidemiological model.
Horizontal body locations received 2.0-2.5 times more UV than vertical locations. The dose associated with having lunch outdoors every day was similar to that from doing outdoor work 1 day per week, but only half that of a seasonal worker. Outdoor work is associated with an increased risk of SCC and also with frequent acute episodes.
Occupational solar exposure contributes greatly to overall lifetime UV dose, resulting in an excess risk of SCC. The magnitude of the estimated excess in risk supports the recognition of SCC as an occupational disease.
暴露于太阳紫外线（UV）辐射是皮肤癌的主要致病因素。户外工作者面临特别的风险，因为他们长时间在户外工作，可能几乎没有遮荫的地方，而且必须在工作场所吃午餐。尽管有流行病学证据表明户外工作者患鳞状细胞癌（SCC）的风险增加了一倍，但将皮肤癌确认为职业病的情况仍然很少。
评估职业性太阳 UV 剂量及其对皮肤癌风险的影响。
使用数值模型（SimUVEx）评估职业和午休时的紫外线暴露，并描述暴露模式和解剖分布。使用现有的流行病学模型估算 SCC 的风险。
水平身体部位接收到的 UV 比垂直部位多 2.0-2.5 倍。每天在户外吃午餐的剂量与每周户外工作一天的剂量相似，但只有季节性工人的一半。户外工作与 SCC 的风险增加以及频繁的急性发作有关。
职业性太阳照射对总寿命紫外线剂量有很大贡献，导致 SCC 的风险增加。估计的风险增加幅度支持将 SCC 确认为职业病。
