SCENIHR is the European Union’s Scientific Committee on Emerging and newly Identified Health Risks. They issue “Opinions” on EMFs every few years, the last having been 2009. On 4 February 2014, they issued a new preliminary Opinion, which is open for consultation until 14 April.
On ELF (ie power-frequency) fields, their main conclusions are:
“The new epidemiological studies are consistent with earlier findings of an increased risk of childhood leukemia with long-term average exposure to magnetic fields above 0.3 to 0.4 μT. However, as stated in the previous opinions, no mechanisms have been identified that could explain these findings. The lack of experimental support and shortcomings identified for the epidemiological studies prevent a causal interpretation.
Studies investigating possible effects of magnetic fields (MF) exposure on the power spectra of the waking EEG, behavioural outcomes and cortical excitability are too heterogeneous to enable drawing any conclusion.
While most studies investigating the effects of ELF MF exposure on symptoms have not found any effects, two experimental studies have identified individual participants who may reliably react to exposure. Replication of these findings is essential before weight is given to these results.
Recent results do not show an effect of ELF MF exposure on reproductive function in humans.”
