Do Compartment Phone Actually Reason
Brain Cancer?
The
cell phone today is more ubiquitous than ever, and scientific studies continue
to try to distinguish the relationship between cellular phones and cancer.
A
recent study from the National Institutes of Health showed increased brain
activity in participants exposed to cell phone radiation. The Brain Cancer
study used PET scans to measure the brain's sugar level, and found increased
activity in regions closest to the phone's antenna after 50 minutes of
exposure. Although the increased activity isn't directly linked to harmful
effects, the human brain's evident sensitivity to the phone's electromagnetic
waves does raise further questions.
In
May 2011, the World Health Organization reclassified cell phone radiation
exposure as "possibly carcinogenic," a label that places it in the
same category as chloroform and lead. The most extensive case control study of
cellular phones and cancer, the Inter phone study, conducted across 13 countries
for a decade found that the highest grade of mobile phone users-those who used
their phones for 30 minutes a day over 10 years or more- were twice as likely
to develop gloom, a malignant brain tumor. These results are alarming,
particularly because the study failed to take into account that children and
young adults are far more susceptible to cell phone radiation than adults.
Cellular
phone radiation testing conducted by manufacturers also underestimates the
amount of radiation that users are exposed to. A recent paper published in the
journal Electromagnetic Biology and Medicine revealed that industry testing is
done on a mannequin modeled after a 6'2", 200 pound man with the phone
held one inch from the mannequin's ear. The study estimates that 97 percent of
the population deviate from this unrealistic model of usage and experience
greater exposure.
The
Federal Communications Commission requires a mobile phone to have a Specific
Absorption Rate (CHAR), a measure of the peak of electromagnetic radiation level
in a model, of less than 1.6 watts per kilogram. However, the peak SAR may not
represent the actual SAR levels of a typical phone call. A cellular phone with
a lower SAR may expose the user to more radiation on average than one with a
higher SAR. A study conducted by a bioengineering research professor, Dr. Henry
Lai, found effects of memory loss in rats exposed to SAR levels as low 0.0006
to 0.06 watts per kilogram.
As
of 2010, there are over 223 million mobile phone users in the US over the age
of 13 and the numbers are constantly growing. According to the CTIA, the
Wireless Association, the total minutes of cell phone use in America in 2009
was 2.3 trillion minutes. Cellular phone users are also starting at younger
ages. Given the indispensable role of cell phones in our lives and the
increasing concern about an association between cell phone use and cancer,
regulatory agencies should carry out more thorough investigations, and cell
phone users should exercise caution and take steps to lower their exposure to
cell phone radiation.
