In the European Journal of Cancer Prevention [5(3):153-158, 1996.] Roger Coghill wrote about the link between electric field exposure and a number of childhood diseases, such as asthenia, headache, depressive illness, and other non-cancer conditions.
The possible association between EMF exposure and childhood leukemia has been indicated by a number of epidemiologic studies. In a more general sense, there are many studies which suggest that EMF can have an effect on various components of the immune system, in some cases activating reactions and in other cases suppressing an immune system response.
Larger scale studies have examined an association between presumed magnetic field exposure and childhood leukemia and recently there has been renewed interest in electric fields as a risk factor, especially in the UK.
