Hailed as the most significant gadget these days, there's still more to find out on cell phones. Considered as an all-encompassing tool, the cell phone has it all. Used for communication, connecting to people all around the globe is no longer impossible. An indispensable tool for people especially to those who are who on the go, the cell phone is now a necessity.
#CellularCountryReview's question is, what's at stake?
1. Cellular Country: Are Cell
Phones Good or Bad?
The Possible Health Effects of
Cell Phones
2. Purpose of the Study
• To know the possible health effects caused by
using cell phones
• To know if cell phones cause cancer?
• To answer if the risk of negative health effects
from cell phones greater if you live closer to a
tower?
• To compare the risk of negative health effects
from cell phones in children and adults
3. Energy from cell phones
• Radio frequency energy.
• Non-ionizing electromagnetic radiation.
• Heat that may damage the body.
4. Can RF energy cause cancer?
• Biological effects caused by RF energy are a result from the heating
of body tissue
• The effects are often referred to as "thermal" effects
• It has been known for many years that exposure to very high levels
of RF radiation can be harmful due to the ability of RF energy to
heat biological tissue rapidly (the principle by which microwave
ovens cook food)
• Tissue damage and cancer growth in humans could occur during
exposure to high RF levels because of the body's inability to cope
with or dissipate the excessive heat that could be generated
• At relatively low levels of exposure to RF radiation (levels lower
than those that would produce significant heating, which are what
cell phones emit) the evidence for production of harmful biological
effects is ambiguous and unproven
5. •This graph shows
that the number of
cell phone users has
dramatically
increased from
virtually zero users in
1985 to 110 million
users in 2001.
Therefore, if RF
energy truly does
yield harmful effects
to humans, more
people are going to
be affected.
6. Factors that affect the level
of exposure to RF energy
• Number of times of calls
• Length of calls
• Cell phone traffic
• Distance from nearest cell phone tower
• Size of the phone/antenna
7. Sources of RF Energy
• Environmental Sources
- broadcast antennas, medical devices, WiFi
• Occupational Sources
- radar installations
• Personal Devices
- cordless telephones, mobile phones/cell phones,
bluetooth
8. Does RF energy affect
children more than adults?
•Children have thinner skulls and developing nervous
systems.
• If RF energy does cause cancer, children would be at a
higher risk than adults.
9. FDA Recommendations
• Limit use of cell phones
• Use hands-free headsets
• Put cell phones far from your brain
