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...
