The primary point of focus has been the possibility of damage to human tissue from the RF energy. Many real and false concerns have been expressed. The major true concern is the potential for tissue damage from exposure from RF energy. RF energy is present in many forms in our daily lives. Each presents varying levels of possible exposure.
Exposure has one common denominator - the amount of RF energy and the distance from the human body.
For example, we are constantly potentially exposed to the RF microwave energy in the home microwave oven. These units are usually installed so the door and viewing glass is eye level - so the user can look into a cavity about I cubic foot or less in size containing active RF energy of 500 to 1200 RF Watts. While the eye is one of the most RF sensitive organs, few, users of microwave ovens have the necessary annual inspections of the units. Even less perform daily cleaning of the seals around the door and fewer still have a readily available tester to conduct weekly tests for leakage of RF energy from the oven. Few people are aware that the common TV sets use 23,000 to 25,000 RF Volts of energy sprayed by electron guns to cause the red, blue and green phosphor dots on the interior of tube face to glow, painting the picture they enjoy.
