what are the potential health issues associated with cellular telephone use?
Whether it’s the increased use of cell phones by children, or the overall increase in cell phone use by adults, human exposure to electromagnetic radiation is happening in ways never dreamed of before. Very young children are using them, teenagers live on them—and some even sleep with them on their pillows, as cell phones are often used as alarm clocks.
What do these exposures consist of and what do they mean for human health?
Whether cell phone use affects the human nervous system and reproduction, causes
DNA damage and behavioral changes, or creates addictive behavior, cell phones are now ubiquitous in our lives. Cell phone technology has changed quickly over time and continues to develop, which means that human exposures also change over time. This report explores what we know about cell phone use, exposures, and human health.

Electromagnetic Radiation
_ All cell phones emit a type of radiation called an electromagnetic field (EMF), composed of waves of electric and magnetic energy moving together through space. Different types of electromagnetic energy are categorized by their wavelengths and frequencies and comprise the electromagnetic “spectrum” (see next page).
_ Different radiation frequencies are used by different technologies.
Radio waves and microwaves emitted by transmitting antennas are a form of electromagnetic energy collectively referred to as radiofrequency (RF) energy or radiation.
_ The RF part of the electromagnetic spectrum consists of frequencies in the range of about 3 kilohertz (3 kHz) to 300 gigahertz (300 GHz). RF energy is used in telecommunications services, including radio and
