Safety Considerations (Model 1225)
Human exposures to RF Electromagnetic field - Biological effect: it
occurs when a change can be measured in a biological system after introduction
of some type of stimuli. Biological effect does not necessarily suggest the
existence of a biological hazard.
A Copy of the following document will be given to the trainee for further
reading: OET bulletin 56 4th edition: August 1999 Questions and answers about
biological effects and potential hazards of RF electromagnetic fields. This
document can be found at the FCC web site www.FCC.gov.
Consequence of employment
Awareness of potential for exposure
Exercise control over the exposure - Stop transmitting
SAR (Watts per kilogram): rate of energy absorbed by (dissipated in)
an incremental mass contained in a volume of dielectric materials such as
biological tissues.
