    reffects of mobile base stations on human health - Presentation Transcript

    1. Health Effects of Radio Frequency Radiation
    2. 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.
    3.  
    4. 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
    5. Water Weight - 65% H20 Dry Weight - 50% Carbon - 25% Oxygen - 10% Nitrogen - 15% All other elements combined We are made from the 4 most reactive elements in the Universe Body Mass
    6. How RF Transfers
    7. What Radio Frequency Affects
      • Directly or indirectly, radiation affects the DNA in cells
      • DNA controls the cell’s function and ability to reproduce
    8. 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)
    9. 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)
    10. Cell Sensitivity
      • Cells most affected:
        • Rapidly dividing cells:
        • (small intestines, bone marrow, hair, fetus)
      • Cells least affected:
        • Slowly dividing cells:
        • (brain, nerves)
    11. 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
      • Genetic
        • Effects that appear in offspring
      • 􀂉 SOMATIC:
      • they affect the health of the
      • irradiated person. They are mainly
      • different kinds of cancer (leukemia is the
      • most common, with a delay period of 2 -5
      • years, but also colon, lung, stomach
      • cancer…)
      • 􀂉 GENETIC:
      • they affect the health of the
      • offspring of the irradiated person. They
      • are mutations that cause malformation of
      • any kind (such as mongolism
    12. Delayed Somatic Effects
      • 1. Cancer: solid tumors
        • Increased risk
      • 2. Cancer: leukemia
        • Increased risk
      • 3. Degenerative effects
        • Life shortening
