In the past, micmwave radiation is generally considered 'good' (hy photon energy of about
KT'^ICf^eV). However, in recent years many studies have shown vivo extremely sensitive to
micmwave and it may cause danger to human health, especially the central nervous system.
Survey results of micmwave radiation exposure eariy in 120 different locatkins in the Hanoi area
(the ama near the BTS) and about 38 handy of diffemnt mobile phone (during the call or hear) the
msults the rate of radiation exposum unstable (fmm 0 0049*C 0OB9mW/cm'), although the capacity is
smaller than a critical thmshold of the Vi/HO (1mW/cm^) and recommended ICNRP (for a 10MHz HF
radiation to 10GHz. SAR<80m WA(g body weight) [5.7] but also the expression is not good for health
(on the observed expression of the body for rabbits). Especially the older generation of phone shave
radiated power (in the first 5 seconds after call or listening to) is gmater than the threshold limit With
the call lasted about 15 minutes, can cause bad effects lo the central nervous system ( EEG
expression)
So we continue to study these issues In order to pmvkie safety measums tor tmusehokls and how
the BTS who frequent exposum to micmwave ..

From year 2000 u.Mo«. the discussions '^*'^' innuencing on living tissues are the
become more and animate, when the new "^^'"'"^ microwares from BTS and from the
mobile systems IMIS (Universal mobile mobile phones [ll-[4]. Based on the initial
telecommunication Svstcms) were penniued for "-^--searched results and on the practicable
