- Humans have always existed in an environment full of energy transmissions. For most of our history, this energy has been amorphous, coming from sources such as cosmic radiation and lightning. Since the introduction of electrical devices (eg, telegraph, light bulb, radio), humans have been exposed to increasing amounts of electromagnetic energy. Today, the variety of devices and their respective energy transmissions seem endless, yet modern life would not exist without these products. However, since the beginning of the electronic age, there have been concerns about the health consequences of exposure to electromagnetic energy.
- The “wired world” envisioned in the 1990s is rapidly evolving into a “wireless world,” where the tether of copper and optical cable no longer binds us to a particular geographic location. Wireless devices are available with a dizzying array of features, from the basic cell phone to full-featured personal computers with many devices in between. In recent years some medical institutions have expressed concern over the impact on patient safety of these wireless devices. These concerns range from interference with medical electronics, decrease in clinical vigilance with the use of the devices, and the effect on the institution's bottom line.
