distribution (22-24). Groups of 10 rats each were exposed to 2.4 GHz at 10, 100, and 1000 µW/cm2, 8
hours/day for 3 months. At the end of the exposure period, the animals were sacrificed and the levels of
copper, manganese, nickel and molybdenum in the major organs were determined by optical
spectroscopy. Changes in the level and distribution of all four elements were found (Table 8.4). The
copper level decreased in both liver and kidney, possibly as a result of increased synthesis of
ceruloplasmin-this would be consistent with the observed increase of copper in blood. There was,
generally, an increase in copper in those organs that use the element in hemopoiesis and redox
processes, possibly indicating a basic compensatory response to EMF radiation. The copper content of
hard tissue was virtually unchanged by the field.
