Influence of a constant magnetic field on human lymphocyte cultures.

The growing exposure to magnetic fields of a certain intensity could represent a serious hazard for our health. In the present note we analyze the effect of a 740 Gauss magnetic field on human lymphocyte cell cultures. From the analysis of our data it is possible to point out that this field produces an inhibition of the cell growth, while does not affect at all the sister chromatid exchange frequency of the chromosomes. Conversely we found a significant increase of chromosome aberrations in the exposed cells. The chromosome aberrations found were mostly gaps and breaks.
