High energy EM radiation is able to ionize atoms through the photoelectric effect. Cellphone radiation is unable to do this because it doesn't have enough energy. This is strictly the case because energy in these scales are quantized.
By high energy you mean low wavelength, right? Because also large wavelengths could transmit a high amount of energy.
Could you explain the connection between these two statements?
Yes the OP doesn't understand the first one therefore the second one might be false.
QED.
If you see something absurd in a HN comment, it's worthwhile to check their comment history. You aren't missing anything or miscomprehending - it's just a troll.
If you don’t like the theoretical explanation given in the sibling comment regarding energy carried by photons, try an experimental approach and get back to us with your results.
