Thank you, Maurice. I am thinking how I will be getting my second tap from you. Have a good day.

Maurice, your statement I'm quoting below is just wrong. "Here's how the harm happens. There are two methods. 1 Combining of a low energy 2GHz photon and a high energy cosmic photon at the same time and place. The high energy photon might not have quite enough energy to do the ionizing action. The low energy photon adds just enough to do the job, like Michael Jordan holding up a one year old to touch a basket while standing flat footed [maybe he'd need a two year old but you know what I mean]. 2 A little bit of heat to topple a chemical reaction into carcinogenicity. Suppose a benzene molecule is tootling through the brain along with the blood carrying it. It bumps into a myeloid leukaemia opportunity but is lacking a little bit of energy to make the connection. Along comes a phone call and dumps a photon handily right on the spot, banging the molecules together just a little bit harder which tips the balance and hey presto, a new myeloid leukaemia is on its way." 1. Photons of very different frequency do not interact or combine. They go through each other and through most matter unless that matter has a specific mechanism to interact with the photon. If a photon has the same frequency as the difference between electronic, vibrational or rotational levels of a molecule it can promote that molecule into a higher electronic, vibrational or rotational energy state; its energy can be absorbed. The frequency of the lowest kind of ionizing radiation is on the order of a million GHz. An ionizing photon doesn't even see a cell phone photon, much less interact or combine. 2. The kind of chemical reactions you are talking about take a great deal of energy. Cell phone photons carry very little energy, not even enough to make molecules spin faster. In fact one cell phone photon carries on the order 10^-24 Joules. (that's 23 zeroes after a decimal point before you get to the 1) That means to get 1 Watt of heating 10^24 photons have to arrive and get absorbed in one second. GHz photons can (quite inefficiently) excite collective oscillations of materials which is the source of heating one gets from 500+ Watt microwave ovens. But cell phones have max powers only on the order of milliwatts and their broadcasts are of very short duration. There is no means for a single molecule to absorb a GHz photon that would promote any kind of specific chemical reaction. Further, there simply isn't enough heat available through excitation of collective molecular motions to disrupt or promote biochemical reactions. Hope this helps, ku
