Abstract
Description
Investigation of possible presence of radiofrequency radiations from mobile at distance not less
than 20cm was carried out within Covenant University, Ota, using ten different handsets. Radiation
measurement was carried out using a cell sensor manufactured by Action Electronic, USA that is
optimized to measure radiofrequency and extremely low frequency radiation. The average power density
from the handsets was 0.10mW/cm2 and 0.45mW/cm2 with highest value from both NOKIA 1100 and
SAGEM My X5 and lowest from SAGEM My X1 at distance not less than 20cm. These results show
that those using handsets are exposed to radiation beyond the background levels but are within the limit
set by the Federal Communication Commission (F.C.C)
