Occupational exposure to electromagnetic fields from medical sources
High exposures to electromagnetic fields (EMF) can occur near certain medical devices in the hospital environment. A systematic assessment of medical occupational EMF exposure could help to clarify where more attention to occupational safety may be needed. This paper seeks to identify sources of high exposure for hospital workers and compare the published exposure data to occupational limits in the European Union. A systematic search for peer-reviewed publications was conducted via PubMed and Scopus databases. Relevant grey literature was collected via a web search. For each publication, the highest...
Exposition aux champs électromagnétiques au travail
Objectifs: La caractérisation des expositions aux ondes électromagnétiques est indispensable dans le cadre de l'évaluation d'un possible risque et pour assurer le suivi adéquat des populations de travailleurs possiblement exposées. L'objectif de ce projet est de décrire les conditions d'exposition aux champs électromagnétiques pour différents postes de travail en bibliothèques et médiathèques. Méthodes: Le protocole permet des mesures discriminant les multiples fréquences aux...
Staff exposure to pulsed magnetic fields during depression treatment with transcranial magnetic stimulation
Introduction. Transcranial magnetic stimulation or repetitive transcranial magnetic stimulation (TMS/rTMS) are currently used in research and treatments of diseases of the central nervous system, such as recurring depression. Strong electric pulses are used to produce strong pulsed magnetic fields that are directed to the patient's cerebral cortex where the fields induce electric pulses. The pulses may be causing unnecessary exposure of the staff. Method. The MagVenture TMS/rTMS system was investigated, without patient presence, through measurements of magnetic field pulses at varying distances...
Health Effects of Electromagnetic Fields on Reproductive-Age Female Operators of Plastic Welding Machines in Fuzhou, China
Objective: The aim of this study was to investigate the health effects of electromagnetic fields (EMFs) among female operators of plastic welding machines. Methods: We examined 180 female operators in shoe factories as the exposed group, and 349 female workers from nearby supermarkets as the unexposed group. Results: The mean radiation levels in the vicinity of the welding machines ranged from 51.3 to 368.9?V/m. The prevalence of neurovegetative symptoms increased with higher EMFs exposures (P?<?0.05). The prevalence of menstrual disorder was 12.0% in the unexposed group, but was 26.8% and 33...
Exposure to MRI-related magnetic fields and vertigo in MRI workers
Objectives: Vertigo has been reported by people working around magnetic resonance imaging (MRI) scanners and was found to increase with increasing strength of scanner magnets. This suggests an association with exposure to static magnetic fields (SMF) and/or motion-induced time-varying magnetic fields (TVMF). This study assessed the association between various metrics of shift-long exposure to SMF and TVMF and self-reported vertigo among MRI workers. Methods: We analysed 358 shifts from 234 employees at 14 MRI facilities in the Netherlands. Participants used logbooks to report vertigo experienced...
Exposure to static magnetic fields and risk of accidents among a cohort of workers from a medical imaging device manufacturing facility
PURPOSE: To study the association between occupational MRI-related static magnetic fields (SMF) exposure and the occurrence of accidents. METHODS: Recent and career SMF exposure was assessed by linking a retrospective job exposure matrix to payroll based job histories, for a cohort of (former) workers of an imaging device manufacturing facility in the Netherlands. Occurrence of accidents was collected through an online questionnaire. Self-reported injuries due to accidents in the past 12 months, and the first (near) traffic accident while commuting to work and from work were analyzed with logistic...
Electromagnetic Fields (EMF) in the welding environment
The Electromagnetic fields (EMF) Directive (2013/35/EU) was adopted in June 2013. Member States are required to bring into force any laws, regulations and or administrative provisions necessary to comply with the Directive by July 1st, 2016. This research report considers various types of welding and the requirements of the Directive. The report provides: - A review of available literature using the TWI “Weldasearch” database and other sources - Measurements of the EMF emissions welders may be exposed to during the welding processes - Understanding where welding fits in with the requirements...
EU-New Directive to protect EU workers from harmful electromagnetic fields
The Directive clarifies the definitions of adverse effects on health, introduces an updated exposure limits system (frequencies that are recognised as having harmful effects on the human cardiovascular system or the central nervous system), as well as a number of provisions to make it easier for employers to carry out the risk assessments required by law. The directive was published in the Official Journal on 29 June 2013 and has to be transposed into national legislation by 1 July 2016. As employers are obliged to carry out risk evaluations, the proposal introduces detailed provisions to ensure...
