It was well known that electric charge came in discrete units, and it was proposed that electrons associated with atoms and molecules had discrete energy based on orbitals and sub-orbitals. Electrons did not have continuous changes in energy. Chemistry was determined by the arrangements of the energies associated with electrons.

To affect chemistry one has to provide enough energy to move an electron from one energy level to another. Photons of X-rays can do this, and we use X-rays to destroy cancer cells. X-rays can cause cancer too. The photons used for cell phone communication do not have the quantum of energy to affect chemistry and can not cause cancer. They can warm tissue, but the power of cell phones is negligible compared to ambient thermal energy.

I was deeply disappointed by the doctor who was on the News Hour and CNN explaining the WHO findings. Radiation is a powerful tool in modern medicine. One would presume that doctors would have some idea on how it works. Media people are idiots by nature.

A cell phone works at about 2 Watts of power. We have a bunch of 50,000 Watt radio stations radiating our brains all the time, not to mention TV stations. The Epidemiological studies reviewed by WHO do not provide accurate exposures. The Agent Orange scare was based on faulty measures of exposure. Sick people remember exposure more that healthy people. My argument above is absolute is is based on one of the greatest intellectual achievements of man.
