There are numerous factors that make ELF-EMF exposure assessment complex and difficult. A substantial amount of research has been published on the relationship between ELF-EMF and adult cancers, but the overall evidence of ELF-EMF health risks remains contradictory or inconclusive. Currently, there are no mandated standards for ELF-EMF exposure in the US, only recommended exposure limits at very high levels as ceiling values. The current exposure assessment methods do not measure all the characteristics needed to act as surrogates for possible adverse health effects suggestive of needs for better exposure assessments and for the development of standardized ELF-EMF measurement protocols. While the research continues on health effects and better exposure assessment design and metric for exposure assessments, concerned individuals, especially workers and employers who work directly with high intensity ELF-EMF sources, can use appropriate combinations of controls to limit exposure.
