UV exposure is considered to be one of the most important risk factors in skin cancers, mainly in outdoor occupational or recreational activities. Outdoor athletes such as cyclists receive regular and significant solar UV erythemal radiation (UVER). The aim of this work was to quantify UVER exposure of amateur cyclists over the course of several days in their training schedules. To quantify UVER exposure of this group, dosimeters (Viospor) were attached at the top of the helmet in the course of their training. The study took place in Valencia, Spain, in June to July 2008 and February to March 2009, and involved a group of five cyclists over a period of 4 days for each period. The mean 2-day personal UV exposure was 32.24 +/- 4.14 SED (standard erythema dose) in summer and 11.30 +/- 5.36 SED in the winter period. One SED is defined as an effective radiant exposure of 100 J m(-2) when weighted with the International Commission on Illumination (CIE) erythemal response function. The mean exposure ratio (ER) of cyclists was 0.37 +/- 0.04 in summer and 0.40 +/- 0.11 in winter. The cyclists received the highest UVER exposure in the summer period, but in both training periods UVER exposure was in excess of occupational and recreational guidelines, indicating that protective measures are very necessary.
紫外线暴露被认为是皮肤癌的最重要危险因素之一，主要与户外职业或娱乐活动有关。户外运动员，如骑自行车的人，会受到定期且大量的太阳紫外线红斑辐射（UVER）的影响。这项工作的目的是量化业余自行车运动员在训练计划中几天内的 UVER 暴露量。为了量化该群体的 UVER 暴露量，在训练过程中，将剂量计（Viospor）贴在头盔顶部。该研究于 2008 年 6 月至 7 月和 2009 年 2 月至 3 月在西班牙瓦伦西亚进行，涉及一组五名自行车运动员，每个时期持续 4 天。夏季 2 天个人紫外线暴露的平均值为 32.24 +/- 4.14 SED（标准红斑剂量），冬季为 11.30 +/- 5.36 SED。一个 SED 定义为当用国际照明委员会（CIE）红斑反应函数加权时，100 J m(-2) 的有效辐射暴露量。夏季自行车运动员的平均暴露比（ER）为 0.37 +/- 0.04，冬季为 0.40 +/- 0.11。自行车运动员在夏季接受的 UVER 暴露最高，但在两个训练期间，UVER 暴露均超过职业和娱乐指南，表明非常有必要采取保护措施。
