In response to the demand from a growing number of people concerned about the possible impact of RF-EMF on health, the French National Frequency Agency (ANFR) has published a standardized protocol for in-situ measurements of radiofrequency electromagnetic fields (RF-EMF). This protocol was based on the search for the point of highest field strength and the use of spot measurement.

In the framework of an epidemiological study, such spot measurements were implemented in the homes of 354 participants located in urban areas within 250 meters of a mobile-phone base station (MPBS) and in the main beam direction of the antenna. Among the participants, more than half accepted to be enrolled in a longer-term study, among whom 152 were equipped with a personal exposure meter (PEM) for 48 hours and 40 for seven continuous days. Both spot and PEM measurements quantified downlink field strengths, i.e. FM, TV3-4-5, TETRA I-II-III, 2GHz-5GHz Wi-Fi, WiMax, GSM900, GSM1800, UMTS900, UMTS 2100, LTE800, LTE1800, and LTE2600.

Spot measurements showed a mean/median field strength of 0.58/0.44 V/m for total RF-EMF and 0.43/0.27 V/m from the MPBS. RF-EMF from the MPBS was the dominant source of exposure in 64% of households. Exposure to RF-EMF was influenced by the position of the windows with respect to the MPBS, in particular line-of-site visibility, the distance of the antenna and the floor of the apartment. The PEM surveys showed the measured exposure to be higher during outings than at home and during the day than at night, but there was no difference between the weekends and working days. There was a strong correlation between exposure quantified by both spot and PEM measurements, although spot measures were approximately three times higher than those by PEMs.

This study is the first to assess exposure to RF-EMF of people living near a MPBS in urban areas in France. These preliminary results suggest the value of using spot measurements to estimate the impact of the evolution of the mobile-phone network and technology on the exposure of populations to RF-EMF. The low levels of RF-RMF expressed as mean values do not necessarily rule out possible health effects of this exposure.

法国手机基地附近居民的射频辐射

为了满足越来越多的人对RF-EMF对健康的影响的关注,法国国家频率局(ANFR)发布了用于现场测量射频电磁场(RF-EMF)的标准化协议。该协议基于对最高场强点的搜索和光斑测量的使用。

在流行病学研究的框架内,在354名参与者的家中进行了这种现场测量,这些参与者位于距离移动电话基站(MPBS)250米以内的城市地区以及天线的主波束方向上。在参与者中,超过一半的人接受了参加长期研究,其中152人配备了48小时的个人暴露测试仪(PEM),连续40天则配备了40个人。点和PEM测量都量化了下行链路场强,即FM,TV3-4-5,TETRA I-II-III,2GHz-5GHz Wi-Fi,WiMax,GSM900,GSM1800,UMTS900,UMTS 2100,LTE800,LTE1800和LTE2600 。

斑点测量显示,总RF-EMF的平均/中值场强为0.58 / 0.44 V / m,MPBS的平均/中值场强为0.43 / 0.27 V / m。来自MPBS的RF-EMF是64%的家庭暴露的主要来源。窗户相对于MPBS的位置,特别是工地可见性,天线与公寓楼板的距离,对RF-EMF的影响受到影响。PEM调查显示,郊游期间测得的暴露水平要比在家中和白天要高,而夜间则要高于夜间,但周末和工作日之间没有差异。尽管现场测量比通过PEM进行的测量大约高三倍,但通过现场测量和PEM测量所量化的暴露之间存在很强的相关性。

这项研究是首次评估法国市区MPBS附近居民暴露于RF-EMF的情况。这些初步结果表明,使用现场测量来评估移动电话网络和技术的发展对人口暴露于RF-EMF的影响具有价值。以平均值表示的低水平RF-RMF并不一定排除该暴露可能对健康造成的影响。
