Radiation on Human Cells

All scientists agree that cell phone radiation and its affect are something to look after [6]. Although cell phone companies insist that there product are safe, the critics fight that this is precisely what the tobacco companies said before its was widely accepted that smoking is a direct factor of lung cancer[3]. All cell phones emit some kind of electromagnetic radiation. When using a cell phone, both sending and receiving calls emit a tiny amount of energy. The cell phone emits non-ionizing radiation and is considered safe. It causes heating in general and some examples of non-ionizing radiation are visible light, radio frequency and microwave radiation [7]. “A radio wave in space is characterized by its frequency, intensity of electric and magnetic fields, direction, and polarization” [66]. The interaction of external radio waves with different body tissues produces internal electric and magnetic fields. These fields can be calculated knowing the different parameters and boundary conditions using Maxwell’s equations. This becomes a difficult problem, since biological bodies are diverse and vary in shape. This makes an exact solution impossible. The boundary conditions are also extremely complicated to calculate since they change dramatically depending on the situation [66]. Scientists are generally interested in how external fields combine with biological bodies to create internal fields. These internal fields will be the ones to interact with the membrane of the nucleus and the DNA it contains. Internal field strength is increasing proportionally with the external field strength. The problem rises when the internal field is not uniform to the external field, which adds complexity to the problem [66]. The magnetic permeability ({m}r =1)of most tissues is equal to that of free space. This means that most tissues are non magnetic. Both electric (E) and magnetic (H) fields decrease exponentially with distance from the boundary of a tissue because of energy loss after reflection.
