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 magnetic field exposure among women in Stockholm County, Sweden.
BACKGROUND Most epidemiological studies on adverse health effects among women in relation to occupational magnetic field exposure have been based on information about men's exposure. AIMS To create a job-exposure matrix for occupational exposure to extremely low frequency magnetic fields among women. METHODS AND RESULTS Measurements were performed using personal magnetic field meters (Emdex...
متن کاملHealth risk assessment of occupational exposure to a magnetic field from magnetic resonance imaging devices.
Health care staff who operate magnetic resonance imaging (MRI) devices are exposed to a static magnetic field of significant spatial heterogenity always produced by MRI magnets during the whole shift. They can also be exposed to pulses of a time-varying magnetic field (gradient field) present only during patients' examinations. The level of the workers' exposure depends both on the type of the ...
متن کاملThe Inhibitory Effects of Static Magnetic Field on Escherichia coli from two Different Sources at Short Exposure Time
This study was intended to investigate the effectiveness of static magnetic field on the growth of Escherichia coli (E. coli) provided from two sources, the urine samples of patients with urinary tract infections and the reference strain E. coli ATCC 25922. Bacterial samples in Nutrient Broth were subjected to a range of magnetic intensities (2, 4, 6, 9, 14, 16, 18, and 20 mT) at various exposu...
