There have been many recent reports regarding the potential risks of UV emissions from compact fluorescent lamps (CFLs). In some of these reports, the robustness of the measurements was difficult to discern. We conducted round-robin measurements, involving three lamp manufacturers and two government research laboratories to gather reliable data on the UV emissions from commercially available CFLs. The initial sample of lamps consisted of 71 spiral-shaped CFLs purchased from local retailers. From the initial sample, 14 "high UV emitting" CFLs were chosen for further evaluation. We compared the UV emissions at a distance of 20 cm with the UV exposure limits (ELs) published by the International Commission on Non-ionizing Radiation Protection (ICNIRP). We found that the allowable exposure time for measured lamps ranged from 21 to 415 h. This indicates that the emissions would not exceed the short-term ELs that have been established by the ICNIRP for healthy individuals. We also evaluated the potential long-term risk and found it to be insignificant. There was a large variation in the UV emissions found, even for lamps from a single package, indicating that it is impossible to predict the UV output of a CFL based on its physical appearance and model designation.
最近有许多关于紧凑型荧光灯(CFL)紫外线辐射潜在风险的报告。在其中一些报告中,测量的可靠性难以辨别。我们进行了循环测量,涉及三家灯具制造商和两个政府研究实验室,以收集市售紧凑型荧光灯紫外线辐射的可靠数据。最初的灯具样本包括从当地零售商处购买的71个螺旋形紧凑型荧光灯。从最初的样本中,挑选出14个“高紫外线发射”的紧凑型荧光灯进行进一步评估。我们将距离灯具20厘米处的紫外线辐射与国际非电离辐射防护委员会(ICNIRP)公布的紫外线暴露限值(ELs)进行了比较。我们发现,被测灯具的允许暴露时间在21至415小时之间。这表明这些辐射不会超过ICNIRP为健康个体设定的短期ELs。我们还评估了潜在的长期风险,发现其微不足道。即使是同一包装中的灯具,其紫外线辐射也存在很大差异,这表明无法根据紧凑型荧光灯的外观和型号来预测其紫外线输出。
