光和电磁场(EMF)对松果体功能的影响可能会导致乳腺癌、生殖异常或抑郁症的长期风险。对新生儿重症监护病房(NICU)的医护人员进行了访谈，以确定他们工作环境中的任务、工作地点和做法以及为婴儿提供的护理。在第一次访问后，开发了测量整个NICU的照度、亮度和宽带合成磁场的方法。对一个托儿所进行了白天(下午1：00)的测量。还有一个晚上(凌晨12：30)参观。对护士和NICU中的早产儿进行相关测量。有些措施不能完成，以免干扰护士在NICU的工作。白天和夜间测量的平均照度分别为184和34勒克斯(IX)，远低于NICU中其他照度研究中报告的照度，最大照度为747 IX。峰值水平可能与那些被认为抑制褪黑素的水平一致。电磁场水平有很高的变异性，在某些医院设备附近超过1,000毫克，但在护士工作站平均为1-2毫克。孵化器内的场超过10毫克。(C)1996年Wiley-Liss，Inc.
Effects of light and electromagnetic fields (EMFs) on pineal function could have implications for long-term risk of breast cancer, reproductive irregularities, or depression. Health-care workers in a neonatal intensive care unit (NICU) were interviewed to determine the tasks, work locations, and practices in their work environment as well as the care provided to the infants. After an initial visit, methods for measuring illuminance, luminance, and broadband resultant magnetic fields throughout the NICU were developed. Measurements were made of one nursery during a daytime (1:00 p.m.) and a nighttime (12:30 a.m.) visit. Measurements relevant to both nurses and premature infants in the NICU were made. Some measurements could not be completed so as not to interfere with nurses' duties in the NICU. Illuminances measured during the daytime and nighttime averaged 184 and 34 lux (Ix), respectively, much lower than those reported in other studies of illuminance in NICUs, with a maximum illuminance of 747 Ix. Peak levels may be consistent with those thought to suppress melatonin. There was a high degree of variability in EMF levels, which exceeded 1,000 mG close to certain hospital equipment but averaged 1-2 mG at the nurses' workstation. Fields within incubators exceeded 10 mG. (C) 1996 Wiley-Liss, Inc.
