Power Density

Definition:  

"Above 30 MHz, the usual unit of measurement is power density, though electric and magnetic fields can also be measured. It is usually expressed in milli- or microwatts per square centimetre (mW/cm2 or uW/cm2), and is defined as the amount of power per unit area in a radiated microwave field or other type of electromagnetic field."

"Research from abroad, partially replicated (and in some instances expanded on) by scientists in English speaking countries, indicates many potential benefits in health, wellbeing and work productivity can be obtained from developing a more comprehensive understanding of potential EMF bio-effects. They also indicate ways in which present communications systems, and the electromagnetic nature of the microenvironments individuals occupy, can be improved to benefit all. It is suggested that the potential cost benefits of adopting improved EMF-hygiene protocols and developing new generations of technology that can actually improve biological functioning and human performance is immense, makes tremendous commercial sense and present enormous commercial opportunities.

"As can be seen in the following table, both beneficial and detrimental biological effects are indicated at exposure levels far lower than those required for 'thermal effects', the traditional marker used to set many guidelines on presently 'acceptable' power density levels.: . . ."
