"This workshop covered issues such as the exposure from mobile phone base stations and other wireless networks, future wireless technologies, review of possible health consequences from the above, risk communication to the public related to radio base stations exposure, and response from governments and other stakeholders. The aim of the conference was to review the current state of knowledge and opinions of the conference participants and propose ways forward on this issue. The meeting was convened by the WHO International EMF Project as part of the scientific review process to determine biological and health effects from exposure to EMF. The purpose of these workshops is to bring together expert scientists so that established health effects and gaps in knowledge requiring further research can be identified."

"With the fast increase of mobile telecommunication and wireless internet also concern is growing. Can exposure to radiofrequency electromagnetic fields lead to adverse health effects? The Health Council of the Netherlands regularly report on this. In the report published today the council concludes: there is no established association between long-term and frequent use of a mobile telephone and an increased risk for tumours in the brain or head and neck area. But such association can also not be fully excluded. The council therefore recommends to keep exposures as low as reasonably possible and to continue investigating effects"

"Depuis les années 1990, les antennes-relais ont vu leur nombre augmenter considérablement en Belgique. Il s'agit d'une conséquence directe de la multiplication des technologies de communication à distance. Depuis longtemps, ces antennes sont employées pour la radiodiffusion, la télévision et les systèmes de radiocommunication mobile utilisés par de nombreuses professions (dont les services de secours). Désormais, s'y ajoutent les réseaux de téléphonie mobile, les équipements portables Wi-Fi, les systèmes de commande à distance, etc. Autant d'applications qui connaissent une croissance constante.
Au sein du public, certaines inquiétudes s'expriment quant aux potentiels effets des « ondes » sur la santé humaine et sur l'environnement. Et cela, d'autant que les antennes ont été progressivement placées de plus en plus près des lieux de vie (habitations, espaces de travail et de loisirs, etc.).
Ce Courrier hebdomadaire examine les cas d'exposition aux « champs composés », c'est-à-dire les cas d'exposition simultanée aux rayonnements radiofréquences émis par plusieurs antennes. Plus spécifiquement, il éclaire les problèmes qui se posent aux ingénieurs chargés de vérifier que les législations prises en la matière par les différentes Régions du pays sont bien respectées.
Avant qu'une nouvelle antenne soit construite, il semble en effet logique que l'administration s'assure, avant de délivrer une autorisation, que le champ électromagnétique qui sera généré, ajouté à ceux déjà produits par les antennes existantes, n'entraînera pas un dépassement des normes édictées. Mais dans les faits, effectuer correctement une telle vérification représente souvent une tâche complexe, voire impossible. Des solutions doivent donc être trouvées. Le problème se pose essentiellement à Bruxelles et en Flandre, la Wallonie ayant adopté une législation qui permet d'éviter les difficultés pratiques liées au calcul du cumul des rayonnements émis par plusieurs antennes."

"The use of the radiofrequency part of the electromagnetic spectrum for mobile telecommunication purposes offers many benefits for daily life. The associated exposure to electromagnetic fields, however, also leads to concerns, for instance on an increased risk of cancer.

The Electromagnetic Fields Committee of the Health Council has performed systematic reviews of the epidemiological data and the data from animal experiments on the relation between exposure to radiofrequency electromagnetic fields and cancer. A report that was published in June 2013 discussed the epidemiological data. The current report Mobile phones and cancer. Part 2. Animal studies on carcinogenesis contains the analysis of the studies on animal experiments. The Committee concludes from this evidence that it is highly unlikely that exposure to radiofrequency electromagnetic fields can cause or stimulate the development of cancer in animals."

"In order to eludicate any health effects from the use of mobile phones, in particular tumours in the head, much research has already been performed. Currently data is available for up to 13 year mobile phone usage. It shows no clear evidence that using a phone for such a time period results in an increased risk for brain tumours or other tumours in the head. Nothing can be said about any risks associated with longer use: for this we need studies running for a longer time. This is what the Health Council of the Netherlands writes in an advisory report that has been presented to the State Secretary for Infrastructure and the Environment.

Weak and inconsistent evidence

The conclusions in the report result from an elaborate search and evaluation of the evailable epidemiological studies into a possible association between the incidence of certain tumours in the head and exposure to the radiofrequency electromagnetic fields from mobile telephones. The strong and weak points of the studies have been analysed and the results have been weighted.

Only for gliomas (malignant brain tumours) weak and inconsistent indications for an association with longterm use of a mobile phone were found. A the same time no increase of this type of brain tumour was observed in the cancer statistics of the Netherlands.

Indications for possible associations with meningiomas (tumours of the meninges), acoustic neuromas (tumours on the acoustic nerve) and parotid gland tumours were even weaker.

Importance of continuation of research

More information will have to be provided by epidemiological studies performed over a longer time period, and by following the cancer statistics for a longer time. For it is possible that the socalled latency time (in this case: the time period between the exposure and the manifestation of the tumour) is (much) longer than 13 years. If that would be the case, studies would show any association after an extended time period only.

"Depuis 1980, la technologie d'identification par radiofréquence (RFID) a connu un fort développement, lié dans un premier temps au besoin grandissant en matière de traçabilité. Face aux avancées technologiques et à la réduction des coûts, le champ d'application de la RFID s'est largement étendu et de multiples secteurs d'activité bénéficient aujourd'hui de cette technologie.Le travail de veille technologique synthétisé dans ce document confirme l'étendue des applications de la RFID à la prévention des risques professionnels en entreprise ; de la gestion des EPI (équipements de protection individuelle) jusqu'aux interrupteurs "de sécurité", en passant par les dispositifs "de sécurité" ou "d'avertissement" dédiés à la détection de personnes.Conscients du potentiel de cette technologie et de ses nombreuses applications possibles, les industriels et les chercheurs travaillent au développement de cette technologie en optimisant les performances, les coûts et les moyens de production ; mais également en intégrant la RFID dans des systèmes plus globaux permettant d'assurer des fonctions plus complexes."

"This document addresses the current scientific evidence concerning exposure to high frequency electromagnetic fields (EMF) and the resulting consequences for health. The following review was conducted by the ICNIRP Standing Committees in cooperation with its Consulting Members. It covers all scientific aspects relevant in this area which include numerical dosimetry, measurements, biological laboratory investigations in vitro and in vivo, as well as epidemiological findings. This review was motivated by the needs of the World Health Organization's International EMF Project and ICNIRP's own agenda of reviewing its guidance and advice on the health hazards of EMF exposure. Since the 1998 publication of the ICNIRP guidelines on limiting exposure to electromagnetic fields, there have been important studies published, that need detailed analysis and discussion to determine their implications for health. This review only addresses high frequency EMFs from 100 kHz to 300 GHz. It aims at providing input to the respective health risk assessment currently undertaken by the World Health Organization (WHO)."
