鉴于通信服务的快速增长和互联社会的前景，监测普通人群可能暴露的非电离辐射（NIR）水平并将其与现行标准中规定的限值进行比较至关重要。大量人群会光顾购物商场，且这些地点通常在公众附近设有多个室内天线，因此这类场所必须进行评估。为此，本研究展示了在巴西纳塔尔市一家购物商场进行的电场测量结果。我们提出了六个测量点，遵循两个标准：人流量大的地方以及存在一个或多个分布式天线系统（DAS）且与WiFi接入点共站或非共站的地方。结果根据与DAS的距离（条件：近和远）以及商场内人流密度（场景：人少和人多）进行展示和讨论。测得的电场峰值最高分别为1.96和3.26 V/m，分别对应于国际非电离辐射防护委员会（ICNIRP）和巴西国家电信局（ANATEL）规定限值的5%和8%。
英文摘要
It is crucial to monitor the levels of Non-Ionizing Radiation (NIR) to which the general population may be exposed and compare them to the limits defined in the current standards, in view of the rapid rise of communication services and the prospects of a connected society. A high number of people visits shopping malls and since these locations usually have several indoor antennas close to the public, it is therefore a kind of place that must be evaluated. Thus, this work presents measurements of the electric field in a shopping mall located in Natal, Brazil. We proposed a set of six measurement points, following two criteria: places with great the flow of people and the presence of one or more Distributed Antenna System (DAS), co-sited or not with WiFi access points. Results are presented and discussed in terms of the distance to DAS (conditions: near and far) and flow density of people in the mall (scenarios: low and high number of people). The highest peaks of electric field measured were 1.96 and 3.26 V/m, respectively corresponding to 5% and 8% of the limits defined by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and the Brazilian National Telecommunication Agency (ANATEL).
