The Different Types of Wireless Radiation
The kinds of wireless and RF exposures to be aware of fall into three categories:
1) Wireless Technologies, 2) Dirty Electricity and 3) Radio Towers and Radar.
1. Wireless Technologies. The first exposure is what you would expect—wireless exposures from cell towers, cell phones, wireless routers and networks, wireless computer equipment (mice, printers, keyboards, etc.), microwave ovens, as well as wireless medical monitoring equipment, wireless energy management systems, “smart” utility meters and grids, etc. It also includes radiation emitted between the handset and base unit of a portable phone, though many people do not realize portable phones emit microwave radiation like cell phones.
2. Dirty Electricity. The second category of concern is radio frequency radiation (RF) that gets on the wiring in homes, offices and schools. One can think of it as radio frequency ‘noise’ superimposed upon a 60-hertz electrical current. This is called dirty power, dirty electricity or ‘high frequency transients.’ This noise is a result of various factors, including electronic equipment inside a building that must convert between alternating and direct current. Dirty electricity also gets onto wiring from high RF environments outside, and from dirty power associated with operation of cell towers in a neighborhood.
Compact fluorescent bulbs and dimmer switches also create dirty electricity, as do many other ‘green technologies,’ such as solar panels, though generally speaking the ‘green building’ field is mostly focused on ‘green materials’ and energy efficiency and not yet on electromagnetic fields. Dirty electricity is carried throughout the electrical circuit in a building irrespective of where it originated. So even if a compact fluorescent bulb is not being used in a given classroom, for example, or there is not electronic equipment in a room, if dirty electricity is being generated somewhere else along the electrical circuit serving that room from CFLs or electronics, children and teachers in that room are potentially impacted, as well.
3. Radio Towers and Radar. Finally, if you are near sources of radio transmission, such as emergency communications transmitters (police, fire, medical), a broadcast radio or TV tower, or even an amateur radio transmitter, it is important to check the levels of radio frequency exposure. Radar at airports, weather monitoring facilities, near highways or found aboard ferries, are also microwave sources to consider.
It is important to minimize all of the above types of fields because, other than the long-term effects not being fully understood, exposures have been linked to: ADD, memory difficulties, irritability, stress, interpersonal disorders, heart irregularities and much more.
