Resumen |
Study carried out to determine the quantity of energy absorbed when the field intensity remains stable while the other parameters of the field and the dimensions and location of the biological model vary. Basing his work on the theory of quasi-stationary fields and the theory of electric circuits, the author constructed an electrical scheme equivalent to cylindrically-formed biological models placed in parallel to the line of forces of the high frequency field. He calculated the mean value of the absorption coefficient in the 0.1 to 100MHz frequency range for models 1.8, 1.5 and 0.18m in length, and demonstrates that this coefficient is dependent rigorously on the geometry of the model and its location in relation to the source of the field. He concludes that knowledge of the intensity and frequency of fields is not in itself sufficient to enable their biological effects on man to be measured exactly for the purpose of declaring electromagnetic fields to be harmful to man or not. |
