Electromagnetic fields and the risk of childhood cancer

Transmission, distribution and use of electricity gives rise to electric and magnetic fields in the extremely low frequency band (ELF-EMF). Such fields are ubiquitous in modern industrialized society. Although there is no biologically established mechanism by which they could play a role in the development of cancer, this topic has become a focus of public concern and scientific debate. This presentation focuses on some of the methodological issues surrounding epidemiological research into the possible relation between ELF-EMF exposure and childhood cancer. Existing data are reviewed, and some ongoing projects are described
