Introduction: Extremely low frequency magnetic field is a part of electromagnetic spectrum with frequency range from 30-300 Hz, which effects on the mental and physical health. In the current conditions, some of the labor affairs authorities believe that psychological problems are the main problem among the workers. The present study was designed to assess general health and depression in worke...
The objective of this paper is to survey the results of studies on the biological effects of electromagnetic fields on fish. First, the basic concepts of electromagnetism and electromagnetic spectrum and the importance of studying it in the case of fish are discussed. Then a summary of the results obtained on the effects of extremely low frequency electromagnetic fields (ELF-EMFs) and radiofreq...
OBJECTIVE To characterize the exposure to electric fields and magnetic fields of non-ionizing radiation in the electromagnetic spectrum (15 Hz to 100 kHz) in the dwellings of children from the Spanish Environment and Childhood-"INMA" population-based birth cohort. METHODOLOGY The study sample was drawn from the INMA-Granada cohort. Out of 300 boys participating in the 9-10 year follow-up, 123...
Fracture-healing is a highly complex and timely orchestrated process. Non-healing fractures are still major clinical problem treatment remains difficult. A 16 Hz extremely low-frequency pulsed electromagnetic field (ELF-PEMF) was identified as non-invasive adjunct therapy supporting bone-healing by inducing reactive oxygen species (ROS) Ca2+-influx. However, ROS Ca2+-influx may stimulate neutro...
Introduction: Electromagnetic field emitted by laptops are known as extremely low frequency (ELF) Waves. The aim of this study was to investigate the intensity of electric and magnetic field with extremely low frequency emitted by common laptops. . Material and Method: Intensity of electric and magnetic field were measured on four sides of 40 common by used laptop at the distance of 30, 60 and...
