Thanks Joanne,
At the start of your letter you refer to the magnetic component. It is absolutely vital that you grasp the point that the electric component of EMFs is the bioactive agent, not the magnetic component. Research focus only on the magnetic component is the disgraceful deception practised by the power utilities for decades, so that the true impact of exposure has been hugely understated. You will have heard of the electric chair, but never the magnetic chair!
That is why EPRI’s EMDEX meters never capture the electric field. They were deliberately designed to avoid epidemiological research into electric field effects, yet Ross Adey’s work on calcium efflux, Bary Wilson’s work on melatonin, and Dan Lyle’s work on lymphocyte competence, to name but a few, as well as the early Russian studies, were all reporting electric field effects, not magnetic. Our vital processes (heart beat rate, brain rhythms etc), are all electric processes, not magnetic, and through superposition (an established physical phenomenon) any other electric field will perturb them.
Please stop using the term magnetic when the culprit is electric. This EPRI deception must be halted if we are to make any progress in research evidence.

Moreover there is no fixed correlation between the two at ELF frequencies, so magnetic field measurements say nothing about electric field effects.

Safety of the magnetic field generated by a neuronal magnetic stimulator: evaluation of possible mutagenic effects
Objective: The possible mutagenicity of a magnetic stimulus was checked using the Ames test with Salmonella typhimurium TA98 and TA100 as tester strains.
Methods: Samples of these bacteria were exposed to a pulsed magnetic field, on the order of 1 T. The magnetic pulses were generated by a neuronal magnetic stimulator with a flat coil. The magnetic stimulus was a continuous sequence of slightly damped half sinusoids at a rate of 5 pulses/s. Exposure times were 2–5 and 15 min. Exposure position was such as to maximise the magnetic field and minimise the induced electric field. Room temperature was maintained at 28.5±0.5°C and the temperature was measured inside the samples.
Results: None of the exposure conditions showed any increase in mutation in either of the two bacterial strains.
Conclusions: These results are discussed in comparison with effects found in the literature. The magnetic stimulation used under the conditions of this study does not appear to have mutagenic effects. This does not apply to cases where both strong electric and magnetic fields are present.
