Electromagnetic radiations and cancer. Cause and prevention.
The various types of electromagnetic radiation differ considerably in their ability to induce cancer. The potential of radiofrequency or microwave radiation and low-frequency electromagnetic radiation to alter DNA is very limited, because their energy is too low to produce substantial ionizations. They are therefore unlikely to be carcinogenic by any direct mechanism. Epidemiologic studies of the carcinogenicity of microwave radiation are basically negative. Studies of workers with relatively high exposures to low-frequency electromagnetic fields have suggested that such persons may be at somewhat elevated risk for leukemia, especially of the acute myeloid type, but the studies have had methodologic weaknesses and mixed results. The association is not proven at this point, but neither can it be ruled out. For ionizing radiation, which is clearly carcinogenic, major questions pertain to how to define the magnitude of risk from low doses and low dose rates, how to identify subgroups of people who are especially susceptible to the effects of ionizing radiation, and how to minimize radiation exposure. When fortuitous radiation exposure from manmade sources, such as radioactive releases from nuclear power plants, are examined in the context of the total exposure people receive from natural sources, medical irradiation, etc., they are almost always found to be small by comparison. Quantitatively, two sources of radiation provide the greatest opportunities for exposure reduction: abatement of radon levels in homes, and reduction in medical radiation exposures.
