| WHAT IS NON-IONIZING RADIATION,
AND HOW DOES IT DIFFER FROM IONIZING RADIATION?
The energy associated with electromagnetic radiation depends on its frequency (or wavelength); the greater the frequency (and shorter the wavelength), the higher the energy. Therefore, x-radiation and gamma radiation, which have extremely high frequencies, have relatively large amounts of energy; while, at the other end of the electromagnetic spectrum, ELF radiation is less energetic by many orders of magnitude. In between these extremes lie ultraviolet radiation, visible light, infrared radiation, and RF radiation (including microwaves), all differing in energy content. Of the various forms of electromagnetic radiation, x-radiation and gamma
radiation represent the greatest relative hazard because of their greater
energy content and corresponding greater potential for damage. In fact,
X-rays and gamma rays are so energetic that they can cause ionization
of atoms and molecules and thus are classified as "ionizing"
radiation. Ionization is a process by which electrons are stripped from
atoms and molecules, producing molecular changes that can lead to significant
genetic damage in biological tissue. Less energetic forms of electromagnetic
radiation, such as microwave radiation, lack the ability to ionize atoms
and molecules and are classified as "non ionizing" radiation.
It is important that the terms, "ionizing" and "non ionizing,"
not be confused when referring to electromagnetic radiation, since their
mechanisms interaction of the human body are quite different. Biological
effects of (non ionizing) RF radiation are discussed in a later section. WHAT BIOLOGICAL EFFECTS CAN BE CAUSED BY RADIATION? There is a relatively extensive body of published literature concerning the biological effects of RF radiation. The following discussion only provides highlights of current knowledge in this area. It has been known for some time that high intensities of RF radiation can be harmful due to the ability of RF energy to heat biological tissue rapidly. This is the principle by which microwave ovens cook food, and exposure to high RF power densities, i.e., on the order of 100 mW/cm² or more, can result in heating of the human body and an increase in body temperature. Tissue damage can result primarily because of the body's inability to cope with or dissipate the excessive heat. Under certain conditions, exposure to RF power densities of about 10 mW/cm² or more could result in measurable heating of biological tissue. The extent of heating would depend on several factors including frequency of the radiation; size, shape, and orientation of the exposed object; duration of exposure; environmental conditions; and efficiency of heat dissipation. Biological effects that result from heating of tissue by RF energy are often referred to as "thermal" effects. Two areas of the body, the eyes and the
testes, can be particularly susceptible to heating by RF energy because
of the relative lack of available blood flow to dissipate the excessive
heat load. Laboratory experiments have shown that short-term exposure
to high levels of RF radiation (100-200 mW/cm²) can cause cataracts
in rabbits. Temporary sterility, caused by such effects as changes in
sperm count and in sperm motility, is possible after exposure of the testes
to high level RF radiation. In addition to intensity, the electromagnetic frequency of RF radiation is important in determining the relative hazard. At a distance of several wavelengths from a source of RF radiation, whole body absorption of RF energy by humans will occur at a maximum rate when the frequency of the radiation is between about 30 and 300 MHz. Because of this "resonance" phenomenon, RF safety standards take this frequency dependence into account. Therefore, as discussed in a later section, the most stringent standards are in this frequency range of maximum absorption. At relatively low levels of exposure to RF radiation, i.e. , field intensities lower than those that would produce significant and measurable heating, the evidence for production of harmful biological effects is less clear . A number of reports have appeared in the Russian and East European literature claiming a wide range of low-level biological effects. The low-level effects on animals and humans reported in the Soviet and East European literature have included behavioral modifications, effects on the blood forming and immunological system, reproductive effects, changes in hormone levels, headaches, irritability, fatigue, and cardiovascular effects. However, further research is needed to confirm the existence of these effects and to determine whether they might constitute a health hazard, particularly with regard to long-term exposure. In recent years some Western scientists have also reported biological effects after exposure of animals and animal tissue to relatively low levels of RF radiation. These effects, often referred to as "non thermal" effects, have included changes in the immune system, neurological effects, behavioral effects, evidence for a link between microwave exposure and the action of certain drugs and compounds, and a "calcium efflux" effect in brain tissue (discussed below). Experimental results have also suggested that microwaves might be involved in cancer "promotion" under certain conditions. However, contradictory experimental results have also been reported in many of these cases, and further experiments are needed to determine the generality of these effects and whether they constitute a threat to human health. It is possible that "non thermal" mechanisms exist that could cause harmful biological effects in animals and humans exposed to RF radiation. However, whether this is the case remains to be proven. One
of the "non thermal" biological effects that appears to be reproducible
is the "calcium efflux" effect. This effect can be described
as the observation that the release of calcium ions from animal brain
tissue is enhanced after exposure to certain low intensities of RF radiation
under discrete conditions of frequency and signal modulation. This effect
has been observed at RF levels well below those necessary to produce heating
of tissue . The extent to which this effect might indicate a hazard is
not presently known, and further research is needed to determine the relevance,
if any, of this phenomenon to human health. There are also biological waves (Bioradiation) emitted & resonanced by plants, animals, viruses, bacteria etc. Human Body Frequencies Human Body Cell - 1,520,000 to 9,460,000 Hz * Refer to "Human Tolerance to Whole Sinusodal
