Occupational exposure of dentists to extremely-low-frequency magnetic field.
OBJECTIVE To compare occupational exposure to extremely-low-frequency magnetic field (ELF-MF) between dentists practicing in dental clinics and those employed in hospitals. METHODS Thirty-two dentists who worked at clinics (n=15) and 33 dentists employed at hospital dental departments (n=7) voluntarily provided their informed consent to participate in this measurement study. The study dentist...
متن کاملOccupational exposure to extremely low-frequency magnetic fields and brain tumor risks in the INTEROCC study.
BACKGROUND Occupational exposure to extremely low-frequency magnetic fields (ELF) is a suspected risk factor for brain tumors, however the literature is inconsistent. Few studies have assessed whether ELF in different time windows of exposure may be associated with specific histologic types of brain tumors. This study examines the association between ELF and brain tumors in the large-scale INTE...
متن کاملEffect of occupational exposure to extremely low frequency electromagnetic fields on level of thyroid hormones effective on fatigue
Background: The aim of this study was to assess exposure to extremely low frequency electromagnetic fields (ELF-EMFs) and its effects on secretion of thyroid hormones associated with symptoms of fatigue on electric arc welding workers. Methods: This study was carried out on two groups including 35 welders (as exposed) and 35 non-welders (as control). Extremely low frequency electromagnetic fie...
متن کاملExposure of school employees to extremely low frequency magnetic fields.
This study was initiated to determine and compare daily occupational exposure (OE) and non-occupational exposure (NOE) of three employee groups of teachers, maintenance workers and secretarial staff in a Canadian school district. The time-weighted average (TWA) individual OE for subjects ranged from 0.4-3.8 milligauss (mG), and the TWA NOE ranged from 0.2-7.1 mG. TWA OE and NOE were 1.2 mG and ...
متن کاملOccupational exposure to extremely low frequency electric and magnetic fields and Alzheimer disease: a meta-analysis.
BACKGROUND Among potential environmental risk factors for Alzheimer disease (AD), occupational exposures have received some attention, including extremely low frequency electromagnetic fields (ELF-EMF). A systematic review and meta-analysis of published epidemiological studies on this subject was carried out. METHODS The search was concluded in April 2006. Bibliographic databases consulted in...
