A new report from BanklessTimes (via AndroidCentral)
lists the smartphones that emit the most radio frequency (RF)
radiation. While the BanklessTimes notes that all smartphones release
some level of RF Radiation, it also points out that there is no proof
that such radiation can hurt humans.
The SAR score for the Motorola Edge surpasses FCC limits in the states according to this report
Bankless
Times rated handsets for RF radiation based on its SAR figures. This is
the specific absorption ratio which measures the rate at which the
human body absorbs radio frequency electromagnetic field (RF-EMF) waves.
The results are listed in watts per kilogram (W/Kg). The handset ranked
number one in radiation is the Motorola Edge with an SAR measurement of 1.79W/Kg which exceeds the FCC's maximum limit of 1.6W/Kg.
Behind the Edge is ZTE's Axon 11 5G with a SAR rating .20W/Kg less than that of the Edge AT 1.59W/Kg. Third is the OnePlus 6T
with a SAR rating of 1.55W/Kg. This is not a top ten list that phone
manufacturers are proud to be on, so we don't think that Sony executives
are turning cartwheels over the firm's placement of two phones in the
top ten. The Xperia XA2 Plus and Xperia XZ1 Compact finished at number four and number eight with SAR ratings of 1.41W/Kg and 1.36W/Kg respectively.
Three Google
Pixel models made the top ten as the Pixel 3 XL's SAR rate of 1.39W/Kg
placed it fifth followed by the 1.37W/Kg RF radiation rate belonging to
the Pixel 4a. The Pixel 3 was tied for ninth with the OnePlus 6. Both
handsets had a SAR rate of 1.33W/Kg.
The top ten smartphones with the highest SAR ratings
In various countries, regulatory agencies have set
maximum SAR ratings that devices are allowed to emit in order to reduce
the possibility that device toting consumers will get cancer. In the
U.S., the FCC limits cellphones to have a SAR no higher than 1.6W/Kg.
The only phone to top that figure on BanklessTimes' list is the Motorola
Edge
The report states that all cellphones
release some radiation, The factors that determine how much include the
type of handset, the model, the age, and how powerful its antenna is.
Also important is the distance of the phone from the closest cell tower.
Phones that emit RF radiation usually just warm up the area of the body
that is right next to the phone, although that is not enough radiation
to warm up the body significantly.
The FCC
suggests that to limit exposure to RF radiation, consumers should limit
their exposure to cellphones, use cellphones for shorter periods, and
use hands-free technology.
ZTE had two phones at the top of the list with the lowest SAR scores
The
data used by BanklessTimes comes from the German Federal Office for
Radiation. Other sources show conflicting data with one test of the Edge
(2020) coming in at .81W/Kg and the 2021 model weighing in at 1.00W/Kg,
both well under U.S. and EU limits.

Once again using data from the German Federal Office
for Radiation, the Android phones with the least amount of radiation
starts with the ZTE Blade V10 with an SAR rating of .13W/Kg. That is
followed by the ZTE Axon Elite and its .17W/Kg rating. The third safest
Android device is the Samsung Galaxy Note 10+ 5G (.19W/Kg) followed by
the Samsung Galaxy Note 10 (.21W/Kg), Samsung Galaxy A80 (.22W/Kg),
Samsung Galaxy A72 (.23W/Kg), the LG G7 ThinQ (.24W/Kg), and the Galaxy
S20 FE (.24W/Kg).
Rounding out the top ten is
the Samsung Galaxy M20 at number 9 and the Honor 7A at 10 with SAR
scores of .25W/Kg and .26W/Kg respectively. Motorola got some measure of
revenge thanks to the SAR rating of the Razr 5G which was .27W/Kg
giving it the 13th lowest SAR rating among the Android phones emitting
the least amount of radiation.
