Eric van Rongen:
“Contrary to many 5G conspiracy theories, phone radiation heats the human body the equivalent of having a cup of hot tea every two hours.”
“The science is really straightforward — there’s simply no solid evidence that anything other than a small amount of body heating may result from exposure to 5G radiofrequency fields.”
Andrew Goldsworthy (Biologist) responds to ICNIRP’s Eric van Rongen’s post featured above:
There are two main mechanisms by which non-ionising radiation such as that from cell-phones can damage living organisms. One is the heating effect and the other is the effect of low-frequency modulation.
1 The heating effect.
We cannot assume that the heating effect is uniformly distributed through living cells. The cells themselves are highly conductive, whereas the cell membranes have a very high resistance. Therefore, for any given current flowing through a tissue, nearly all of the heat will be generated in the cell membranes. Since these membranes constitute only about one thousandth of the total diameter of a typical cell and virtually all of the heat is being generated in them, the ICNIRP Guidelines, which are based on the assumption that cells and tissues are uniformly conductive, are approximately one thousand times too high.
2 The effect of modulation.
Living cell membranes are electrically non-linear and have a voltage across them of approximately 70mV. They are pierced by countless ion channels that behave like electrically biased Schottky diodes capable of rectifying and so demodulating any alternating signal (including microwave frequencies) with the demodulated low frequency components appearing between the inside and outside of the cell. This is what does most of the damage and here is why:
The cell membrane is mainly made of a lipid bilayer only about 10nM thick, with proteins such as ion channels “floating” in it. The membrane itself is negatively charged because it has outwardly directed negatively charged phosphate groups and is normally stabilised by divalent positive calcium and magnesium ions that cross-link them. But the demodulated cell-phone signal makes the negative membrane and its protective divalent ions move in opposite directions. This destabilizes the membrane and makes it more likely to perforate and collapse the voltage gradient across it. This, in turn, opens voltage-gated calcium ion channels in the membrane that let huge numbers of calcium ions into the cell down a massive 10,000:1 electrochemical gradient.
In nature, this increase in the internal calcium concentration is taken as an indicator to the cell that its membrane (and by implication, the whole cell) has been damaged and sets in train a series of repair mechanisms, which uses a great deal of metabolic energy. If it succeeds, the cell is repaired, if not, the cell dies, but either way a great deal of energy is used. This may in large part explain the chronic fatigue syndrome that was found in early mobile phone users (Yuppie flu) and is now much more widespread in the community due to our constant exposure to cordless phones, their base stations, WiFi and all the other wireless devices that current ICNIRP guidelines regard as safe.
Lastly, the relationship between 5G and COVID-19.
We cannot assume that because the 5G radiation is mainly absorbed by the skin that it cannot damage the rest of our bodies. If the energy of the radiation is disproportionately absorbed by the skin, then the damage to the skin and the blood and lymph circulating through it will also be disproportionately large. The effects of 5G on lymphocytes could be particularly damaging. They too will have their energy drained by the calcium influx caused by the radiation, have less to spare to generate their protective antibodies and so make the immune system less efficient. So, I guess you could say that 5G can promote the spread of COVID-19. That said, most other forms of information carrying (i.e.modulated) frequencies may be even more dangerous, particularly WiFi with its extremely low frequency (10Hz) beacon signal being possibly the most dangerous.
