Jan 1, 2025
This case-control study in Mexico City (2017–2022) evaluated residential ELF-MF and device-use proxies for RF exposure in relation to childhood CNS tumor risk. Elevated residential ELF-MF (≥0.4 μT) was associated with approximately doubled odds of CNST, while cell phone use showed no association. Prolonged tablet…

Jan 1, 2025
This population-based case-control study in Montréal (2008–2011) evaluated occupational extremely low-frequency magnetic field (ELF-MF) exposure and postmenopausal breast cancer risk using a job-exposure matrix linked to lifetime job histories. Overall, it reports no association between occupational ELF-MF exposure…
Carcinogenicity of extremely low-frequency magnetic fields: A systematic review of animal studies
Research
RF Safe Research Library
Jan 1, 2025
This PRISMA-based systematic review evaluated 54 animal studies on the carcinogenicity of extremely low-frequency (ELF) magnetic fields. The authors report very little evidence that ELF magnetic fields alone are carcinogenic. Findings on co-carcinogenicity (ELF MFs combined with other agents) are inconclusive, and…

Jan 1, 2023
This in vitro study exposed human osteosarcoma (MG-63) cells to 2 mT extremely low-frequency magnetic fields with sinusoidal, triangular, or pulsed waveforms under continuous (3 h) or fractionated (3 days) conditions. The authors report significant decreases in proliferation and shape index in exposed cells versus…

Nov 3, 2015
This Danish case-control study assessed residential extremely low-frequency magnetic fields (ELF-MF) calculated from 50 6400 kV facilities and risk of childhood leukaemia, CNS tumour, and malignant lymphoma from 1968 62003. For 1987 62003, the RR for the combined outcome at 0.4 bcT vs
Occupational exposure to extremely low-frequency magnetic fields and electrical shocks and acute myeloid leukemia in four Nordic countries

Jan 1, 2015
This Nordic case-control study evaluated whether occupational exposure to extremely low-frequency magnetic fields (ELF-MF) or risk of electrical shocks is associated with acute myeloid leukemia (AML). It included 5,409 AML cases and 27,045 matched controls across four countries, with exposures assigned using…
Extremely low-frequency magnetic fields of transformers and possible biological and health effects

Jan 1, 2014
This study measured leakage extremely low-frequency (ELF) magnetic fields around a transformer located on the bottom floor of a three-floor apartment building in Istanbul. The measurements were evaluated against international exposure standards, and the authors report exposures higher than the IARC threshold magnetic…
Effects of low frequency electromagnetic fields on the chondrogenic differentiation of human mesenchymal stem cells.

Jan 1, 2011
This in vitro study examined whether extremely low-frequency magnetic fields affect chondrogenic differentiation of human mesenchymal stem cells in pellet culture. Cells exposed for 3 weeks to a homogeneous sinusoidal 5 mT magnetic field showed increased collagen type II expression (significant at passage 6) and…
