The World Health Organization (WHO), through its International EMF Project, has conducted a number of reviews of possible health effects from exposure to fields from various parts of the electromagnetic spectrum. These fields can be grouped into radiofrequencies (RF), intermediate frequencies (IF) and the static and extremely low frequencies (ELF). In addition, there have been substantial revie...

Background Exposure to electro-magnetic fields is a risk factor for abortion. We aimed to review the relationship between exposure to magnetic fields during pregnancy and the risk of abortion. Materials and Methods: Two independent researchers screened the articles with related keywords including: "Radiofrequency", "RF", "RF-EMFs",...

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

The critical arguments for radiofrequency radiation exposure limits are currently based on the principle that radio frequencies (RF) and electromagnetic fields (EMFs) non-ionising, their even 100-fold lower than those emitted from Sun in whole RF-EMF spectrum. Nonetheless, this argument has been challenged by numerous experimental theoretical studies diverse biological effects of at much power ...

This paper describes the current science-based approach to ensuring public safety from RF-EMF base stations. It acknowledges that a degree of concern persists despite fact dose limits are seldom if ever approached in practice. One plausible contributor discord is tendency within parts academia and by some planning authorities pursue technocratic policy siting wherein concerns attributed scienti...

Quickly changing technologies and intensive uses of radiofrequency electromagnetic field (RF-EMF)‑emitting phones pose a challenge to public health. Mobile phone users and uses and exposures to other wireless transmitting devices (WTDs) have increased in the past few years. We consider that CERENAT, a French national study, provides an important addition to the literature evaluating the use of ...

We investigated the association between exposure to radio-frequency electromagnetic fields (RF-EMFs) from broadcast transmitters and childhood cancer. First, we conducted a time-to-event analysis including children under age 16 years living in Switzerland on December 5, 2000. Follow-up lasted until December 31, 2008. Second, all children living in Switzerland for some time between 1985 and 2008...

Human exposure to background radiofrequency electromagnetic fields (RF-EMF) has been increasing with the introduction of new technologies. There is a definite need for the quantification of RF-EMF exposure but a robust exposure assessment is not yet possible, mainly due to the lack of a fast and efficient measurement procedure. In this article, a new procedure is proposed for accurately mapping...
