& Electromagnetic Radiation& Electromagnetic Radiation
• Cell phones emit radiofrequency energy
(radio waves), a form of
non-ionizing radiation.
• Electromagnetic radiation (EMR)
travels in space in the form of
oscillating electric & magnetic fields

3. Around 50% of cell phone radiation can be
absorbed by the head and body

4. Forms of EMRForms of EMR
• Near Field Intensity (NFI) is the energy which is less
than one wavelength from the source to the user.
• Far Field Intensity (FFI)Far Field Intensity (FFI) is defined as radiation more thanis defined as radiation more than
one wavelength away from the source. This energy form isone wavelength away from the source. This energy form is
required for communication with the cell tower.required for communication with the cell tower.
NoteNote - Exposure to NFI is the major cause for concern among physicians, scientists, &
lawmakers who believe this exposure to be a health hazard.

6. Conclusion
Basis these scientific studies and research reports,
we have come to understand that there isn't any co-relation
between marginal cell phone use and risk of cancer.
