Model		Occupational RF / ELF exposure of parents and correlations with brain tumors in children
Details		Children who died from brain cancer (1959-1978) were studied for correlations with parental occupation and exposure of all types (including microwaves / EM fields). Initial studies found significant correlations with paternal occupation in several industries (agriculture, construction, metal, and food and tobacco) and in several occupations (agriculture, construction work, electrical assembling / installing / repairing in the machinery industry, and transportation). In subsequent reports looking specifically at cases of neuroblastoma and electromagnetic fields (n = 110, children born 1942-1967) identified through the Columbus Children's Hospital Tumor Registry, the authors report a tentative correlation between paternal EM field exposure and neuroblastoma (OR between 1.6 - 1.9), although they caution that more work is necessary to confirm the result. In these studies, it appears that EM field exposure was simply inferred from limited occupational information statements on the birth certificates.
