Exposure for microwave EMF in the Ravne tunnels
People normally wear their mobile phones in their pockets. Mobile phones send «beacon signals» with intervals of few minutes to connect/maintain connection to the nearest base station (antenna).
Also, people more and more have their phones with broadband and wifi always on. Active WiFi equipment normally sends «beacon signals» ten times per second or more, searching for connections. Some even have Bluetooth always on. Some new equipment (iPhones) may have several mobilephone protocols (e.g. 3G and 4G) active at the same time.
When entering the Ravne tunnels, mobile phones will continue searching for contact to mobile base stations and wifi connections, and normally increase the emission power as contacts are not found. Where a group is together inside the tunnel, microwave signalling – and extremely low frequency signals which are part of microwave communication as so called «partial tones» – could reach significant levels.
This could be expected to create unneccesary exposure and biological strain to the carrier of the equipment itself, as well as to other people inside the Ravne tunnels, where they might, paradoxically, be for the opposite reason: to get healed because of the lack of exposure to various biological strains as well as the presence of other healing properties (negative oxygen ions, and more).
Many people – estimated to 5% or more and increasing in modern society – have physical reactions to microwave signals, like headache or dizziness or changed heartbeats, or else, without understanding what the cause might be.
A small test
To test the significance of such exposure, and to underpin my argument with data, I collected, on the 19. September 2017, exposure data by staying for approx. 1,25 hour (15:10 – 16:25) in the «Healing chamber» of the Ravne tunnels, noting the changing exposure measurements as people were passing by, sitting down for a while, og comming with a guide to get explanations about the ionized air and the chamber. I also did less systematic measurements over several hours the two following days while I was working with wheelbarrows around the «Healing chamber» to check that the findings were confirmed.
Measurements were done in a very simple way with my CORNET Electrosmog meter (100 MHz – 8 GHz). This meter has no detailed log, but registers current values and max values, and has a screen where levels and pulses are seen for about 20 seconds. As there was little light, I would mostly have to check for max values and reset at each change of persons. The time intervals between readings are therefore directed by people comming and going.
The measurement unit was microWatts per square meter (µW/m2), which means it was a measurement of exposure, not of emitted signal strength: as exposure decreases sharply with distance, the exposure would be very different if the source was close to the meter or in the opposite end of the «Healing chamber».
The intention was simply to see if exposure went up with higher numbers of people in the chamber, as one could suppose that a substantial amount of them would have their mobile phones on in their pockets. The hypothesis was that it would so, which is common sense, and hence should not require any advanced research procedure.
The hypothesis was confirmed, as can be seen from the log:
15:10, with just myself in the Healing chamber, the exposure measured was stable at 0,5 µW/m2.
15:12, while a friend of mine was first entering and swiching his mobilephone off, then leaving, 68 µW/m2 was registered.
15:14, four persons set down to meditate. Still 0,5 µW/m2.
15:20, one person passes by, leaves a pulse 50 µW/m2. (Decimals not noted from here onwards.)
15:27, this same person comes back and sits down, a pulse of 38 µW/m2 is soon seen.
15:32, three persons sit down and leave after three minutes, pulses of max 55 µW/m2. and 81 µW/m2. are registered.
… and so it continues with exposure values in this same range until a guide with four persons pass, and a max of 400 µW/m2 is measured (15:57). From then on, levels in the range of 33 to 56 µW/m2 are measured until a guide with a group of 15-20 persons (I could not tell the exact number) stayed for seven minutes in the Healing chamber (16:15 – 16:22). During those minutes I registered max values of 102, 110 and 1600 µW/m2 between each reset.
The test was discontinued to reach transport, but, as mentioned, continued less systematically the next to days, with similar results when groups came and stayed in the «Healing chamber». However, I also noticed readings of 140.000, 66,000, 131.000, 36.000, 56.000 and 77.000 µW/m2, that is significantly higher measurements.
Interpretation of findings
The result shows what was expected: pulses are measured from mobile phones, exposure rises to significant levels with groups of people who we should assume have mobile phones and other wireless equipment turned on while in the tunnels.
In 2011, the European council recommended the EU Commission to establish a long term goal of of 100 µW/m2 as maximum mean exposure for the public, while 1.000 µW/m2 was demanded urgently to be established as a maximum mean exposure in the short term. The recommendation was based upon a study of scientific results on negative health effects from microwave exposure.
Though not being mean exposures, but pulsed maximima, the measurements in the «Healing chamber» significantly exeed these recommendations. They are also completely unneccesary, as there is no coverage whatsoever inside the tunnels.
Conclusion and suggested measure to be taken
Everyone entering the Ravne tunnels should be asked, by signs and by their guides, to set their phones, notebooks or other electronic equipment i flight mode or to turn it off – for their own health, as well as for not polluting the Ravne tunnels and diminishing the beneficial health effects other guests might have from visiting the tunnels.
