There have been many studies on the relationship between low-level radiation and cancer. Evidence has been found of relationships with multiple types of cancer including breast cancer, hematological cancers, general cancer, and brain cancer – as reported in the World Health Organization’s Environmental Health Criteria 238: Extremely Low Frequency Fields report.
Risk of hematological cancers (leukemia, lymphoma and multiple myeloma) has been associated with proximity to high voltage power lines. Studies also have shown an increase of brain cancer and acoustic neuroma associated with use of hair dryers and electric shavers. An excess of breast cancer was found among both males and females who have high occupational exposure to ELF (Extremely Low Frequency) and RF (Radio Frequency) fields.
