Electromagnetic fields (EMF) are invisible lines of energy force present everywhere in our environment. EMF, in regards to environmental health exposure, refers to extremely low frequency electric and magnetic fields, ranging from 3 to 3,000 Hz. This range includes power-frequency (50 or 60 Hz) fields. These fields can induce currents within the human body which, if sufficient, can produce a range of effects such as heating and electrical shock. However, to produce such extreme health effects, the fields outside the body would have to be much stronger than present in normal environments.
Common sources of EMF exposure include power lines, appliances and mobile phones. Short-term exposure to very high levels of electromagnetic fields can be harmful to health and is typically applicable to power industry workers. To date, no adverse health effects from low level, long-term exposure to radiofrequency or power frequency fields have been confirmed; however scientists continue to conduct research in this field. Some previous studies had indicated an association between elevated exposure and childhood leukemia.
FACS can provide EMF surveys for homeowners and businesses concerned about EMF exposure. Additionally, FACS can conduct hazard assessments for workers in power, radio, or other industries where exposure to high levels of electromagnetic fields can be expected.
