| Resumen |
Although there is no significant transfer of energy from power-frequency fields to biological systems, some animal cells and tissues respond to such fields in the laboratory. Whole-animal and human experiments have examined 5 categories of effect: on mood or behaviour; on physiological variables such as growth or respiration; on specific biochemicals such as hormones that regulate physiological and psychological functions; on biological rhythms; on the epidemiology of cancer, especially leukaemia and brain cancer. The results are complex and inconclusive, but the epidemiological evidence is beginning to provide a basis for concern about risks from chronic exposure. If power-frequency fields do pose a health risk, high-voltage transmission lines will not be the only source of concern: distribution lines, wall wiring, appliances and lighting fixtures also produce such fields, and are much more common than transmission lines. |
