Safety
consistent test methodology for measuring the rate at which RF is
deposited in the heads of wireless phone users. The test method uses a
tissue-simulating model of the human head. Standardized SAR test
methodology is expected to greatly improve the consistency of
measurements made at different laboratories on the same phone. SAR is
the measurement of the amount of energy absorbed in tissue, either by the
whole body or a small part of the body. It is measured in watts/kg (or
milliwatts/g) of matter. This measurement is used to determine whether a
wireless phone complies with safety guidelines.
9. What steps can I take to reduce my exposure to Radio Frequency energy
from my wireless phone?
If there is a risk from these products — and at this point we do not know
that there is — it is probably very small. But if you're concerned about
avoiding even potential risks, you can take a few simple steps to minimize
your exposure to Radio Frequency (RF) energy. Since time is a key factor in
how much exposure a person receives, reducing the amount of time spent
using a wireless phone will reduce RF exposure. If you must conduct
extended conversations by wireless phone every day, you could place more
distance between your body and the source of the RF, since the exposure
level drops off dramatically with distance. For example, you could use a
headset and carry the wireless phone away from your body or use a
wireless phone connected to a remote antenna. Again, the scientific data
does not demonstrate that wireless phones are harmful. But if you're
concerned about the RF exposure from these products, you can use
measures like those described above to reduce your RF exposure from
wireless phone use.
10. What about children using wireless phones?
The scientific evidence does not show a danger to users of wireless
phones, including children and teenagers. If you want to take steps to
lower exposure to Radio Frequency (RF) energy, the measures described
above would apply to children and teenagers using wireless phones.
Reducing the time of wireless phone use and increasing the distance
between the user and the RF source will reduce RF exposure.
