I found your video most interesting – and a cause for concern.
One query: You stated that CFLs give off microwave radiation (I assume that this means electromagnetic radiation at a frequency above 1 GHz). Why is this? As I understand it, as CFL uses and inverter (perhaps running at a few hundred kHz, so where does the microwave radiation come from?
I’m guessing its because of the switching effect…they save electricity by turning on and off at around 100,000 times a second.
CFLs create not just RF radiation but also UVs and dirty electricity…the evidence is laid out here https://www.electricsense.com/1437/are-cfls-safe-to-use-in-your-home/
Thanks for your reply.
I don’t doubt that CFLs give off RF electromagnetic radiation – and I was interested to read about the UV hazards (though I beleive that halogen lights – especially desk lights – have the potentila to be much worse in this respect).
My issue was with the statement that CFLs give off microwave radiaiton. You confirmed my suggetsion that the inverter in a CFL runs at around 100 kHz (i.e. 0.1 MHz), so I would find it hard to imagine them producting microwave radiation (i.e. at a frequency of over 1000 MHz – or, taking the rather lower figure from Wikipedia, 300 MHz). I would expect harmonics from the inverter to run up to a few MHz (which is why there is audible interference on an AM radio) – but not in the microwave spectrum.
This makes a signifcant difference to the amount of RF energy emitted – as I recall from my school physics class, E=h.f (i.e. energy per ‘packet’ equals Planck’s constant times the frequency) – so one hundredth the frequency corresponds to one hundredth the energy per packet. See http://searchcio-midmarket.techtarget.com/definition/Plancks-constant Whether the related low frequency RF emitted is a problem or not is open to investigation – but it’s not microwaves.
Not trying to be picky, but I think you raise some valid concerns throughout your website (I’m about to invest in some air tune headsets for mobilke and cordless phones), but I’m concerned that this kind of erroneous statement may reduce overall credibility of your important message.
Hope this is helpful
I can see what you are getting at here. RF radiation is how Professor Magda Havas describes the EMFs emitted from CFLs when in fact (as you say) they are in the 100 KHz frequency range and so can’t be RF radiation (according to the WHO RF radiation is in the range 10MHz to 300 GHz). The terminology is confusing…strictly speaking the correct explanation is that CFLs create intermediary frequencies (IFs) (in the 300Hz to 10MHz)…I stand corrected, IFs not microwave radiation would have been the more accurate term to use in this video. The point is IFs are considered dangerous.
Hi Lloyd, will this meter be enough to test my home devices? In your book you mention a few. I am trying to be as economic as possible…
And I am about to start getting my home environment sorted because my symptoms are getting increasingly worse and it is getting more difficult to live a “normal” life….
Thank you for your advice and for doing the research to make this process easier…. I am trying to educate myself but finding it difficult, like learning a new language.
Unfortunately no one meter can test for the presence of EMFs on all frequencies. This is a good 1st meter, it will help you get readings for magnetic and electric fields. A dedicated RF meter is the next step.
Thanks again, I shall be putting the order in for one today.
Could you tell me what you mean by a dedicated RF meter?
Also, could you explain briefly what radiation is and if all of the fields you talk about are radiation?
I was talking with my step Dad last night and he was saying that household appliances etc don’t give off radiation but I don’t believe that to be true especially microwaves and mobile phones.
Thanks again, I am getting through your book on audio and made my first entry into my ES diary today!!
A dedicated RF meter….what I am saying is a meter with a higher level of precision and sensitivity for RF radiation than the Trifield…if your budget is tight the ED75 is a good buy. ‘Radiation’ and ‘electromagnetic fields’ are different ways of talking about energy….the lower frequency fields we call ‘magnetic and electrical fields’ and the higher frequency fields are termed ‘radio frequency radiation’.

What meter would you recommend for measuring power lines, proximities to power lines and in the home.
Thanks in advance,

In order of preference and cost:
– the Trifield 100 XE
– the Gigahertz ME3030B
– the Cornet ED78S: has the advantage of also measuring RF radiation (cell towers, WiFi etc)
