the sum average wave intensity due to superposition of natural unpolarized waves is the sum of individual average intensities each one depending on the square amplitude of individual electric field (Eq. 7), the sum electric field from an infinite number of individual waves (as e.g. with natural light), is zero:

This is why series of parallel RF/microwave antennas are often used to produce high-intensity beams in certain directions18

the wave intensity depends upon the square of the electric field intensity

Solar EMR intensity incident upon a human body ranges normally between 8 and 24 mW/cm2 (depending on season, atmospheric conditions, geographical location, etc) while corresponding intensity from a digital mobile phone handset upon a human head during “talk” emission is normally less than 0.2 mW/cm2  (Refs.  6,12,13

Table 1: Cell renewal rates in different tissues of the human body. Values are rounded to one significant digit. Giving context through daily life replacement processes, we note that hair elongates at about 1 cm per month (BNID 109909) while fingernails grow at about 0.3 cm per month (BNID 109990), which is about the same speed as the continental spreading in plate tectonics that increases the distance between North America and Europe (BNID 110286).

there are about 3×1013 red blood cells to infer that about 100 million new red blood cells are being formed in our body every minute!

In our bodies, this carbon gets incorporated into the DNA of every nascent cell and the relative abundance of carbon-14 remains stable as the DNA is not replaced through the cell’s lifetime.
