Health Effects of Radio Frequency Radiation
Scientific Background
Cellular phones emit microwave radiation in the spectrum region of 800-900 MHz
The rate at which radiation is absorbed is measured by the Specific Absorption Rate (SAR).
Currently, it is difficult to measure the amount ELF absorbed by the fetus due to cellular phone use.
Base Station A typical base station transmit power levels from a few watts to 100watts or more depending on the size of the region or cell Typical Base station antenna is about 30cm wide and a metre long, mounted on building or towers of height of 15 to 50m above ground. Intensity at ground directly under antenna is low. RF field intensity increases slightly as moves away from the base station and then decreases at greater distances

How RF Transfers
What Radio Frequency Affects
Directly or indirectly, radiation affects the DNA in cells
DNA controls the cell’s function and ability to reproduce
Possible Effects
Destroy the DNA
Kill the cell
Damage the DNA; cell can:
Repair itself (most likely)
Not function or function improperly
Undergo uncontrolled division (cancer)
Possible Effects

Cell Sensitivity
Cells most affected:
Rapidly dividing cells:
(small intestines, bone marrow, hair, fetus)
Cells least affected:
Slowly dividing cells:
(brain, nerves)
Category of Effects
Acute Somatic
Immediate effects to the organism receiving the dose
Delayed Somatic
Effects that appear years later to organism receiving the dose
