Coolpad TATTOO Health/Safety/Warranty Guide 35
This is due to the interval between exposure time to a cancer-causing agent and the rate for
which tumors develop - if they do. This could take several years into the future. The
interpretation of epidemiological studies is hampered by difficulties in measuring actual RF
exposure during day-to-day use of wireless phones. Many factors affect this measurement, such
as the angle at which the phone is held, or which model of phone is used.
7. What has the FDA done to measure the Radio Frequency energy coming from
wireless phones?
The Institute of Electrical and Electronic Engineers (IEEE) is developing a technical standard for
measuring the Radio Frequency (RF) energy exposure from wireless phones and other wireless
handsets with the participation and leadership of FDA scientists and engineers. The standard,
“Recommended Practice for Determining the Spatial-Peak Specific Absorption Rate (SAR) in
the Human Body Due to Wireless Communications Devices: Experimental Techniques”, sets
forth the 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
