ABSTRACT |
Background: Mobile phone has become a very popular device used in everyday our lives. However, the possible hazard to human body such as brain tumor has been proposed intermittently. This unwanted possibility was calmed down due to the absence of definite evidence of hazard. This study was performed to see the effect of mobile phone use on the brain temperature. Methods: In 20 volunteers, We performed 4 steps of temperature measuring procedure. Four steps are pre-use (SI, basal state), wire-phone (S2, conventional telephone), PCS phone (S3, using 1,750~1,900MHz), cellular phone (S4, using 820 MHz) states. Brain temperatures were measured by radiothermometer at 10 sites (5 sites in each hemisphere) of the brain after 5 minutes of telecommunication through the phones. The final data were compared using paired t-test. Results: In PCS user group (Average; 35.73708 |
