first 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 are 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
