How safe are cell phones ?
Cell phones are now so popular and convenient that they are
placed as the primary form of telecommunication for many people. But the question that emerged from the
statement is “Is Growing Cell Phone Use
Increasing Health Risks?” Nowadays , we need to admit that cell phone
use continues to grow, so does concern about the possible health risks of
prolonged exposure to cell phone radiation.
Do
Cell Phones Cause Cancer?
Studies on the health risks of cell phone use have produced
mixed results, but scientists and medical experts warn that people should not
assume no risk exists. Cell phones have been widely available for only the 10
years or so, but tumors may take twice that long to develop.
Because cell phones haven’t been around very long,
scientists haven’t been able to assess the effects of long-term cell-phone use,
or to study the effects of low-frequency radiation on growing children. Most
studies have focused on people who have been using cell phones for three to
five years, but some studies have indicated that using a cell phone an hour a
day for 10 years or more can significantly increase the risk of developing a
rare brain tumor.
What
Makes Cell Phones Potentially Dangerous?
Most RF (Radio Frequency) from cell phones comes from the
antenna, which sends signals to the nearest base station. The farther the cell
phone is from the nearest base station, the more radiation it requires to send
the signal and make the connection. As a result, scientists theorize that the
health risks from cell-phone radiation would be greater for people who live and
work where base stations are farther away or fewer in number.
How
to Protect Yourself from Cell Phone Radiation ?
“Precaution” seems to be the approach recommended by an
increasing number of scientists, medical experts and public health agencies,
from the French Health Ministry to the U.S. Food and Drug Administration (FDA).
General recommendations to minimize the potential health risks include talking
on cell phones only when necessary, and using a hands free device to keep the
cell phone away from your head.

cause of it.
Paragraph
2 : about studies of cell phones effect that can emerge in 10 years later but
tumor can be taken twice to emerge.
Paragraph
3 : about the research that focus on the people who using cell phones for three
to five years and using of cell phones for 10 years a day can easily get brain
tumor.
Paragraph

people who live in around the Radio Frequency base station will have a greater
influence to get the effect of the cell phones radiation.
Paragraph
5 : about the precaution of using cell phones by talking on cell phones if it
necessary and we can use hands free device to keep it away from our head when
talking.
