Emotional identification during mobile RF Radiation

This paper presents emotional identification of 62 healthy subjects under Mobile Radio Frequency Radiation (MRFR). Electroencephalography (EEG) at awake and rest status with eyes closed, particularly on Alpha and Beta wave will be investigated. 31 subjects were strapped with mobile phone at the left ear, and name them as LE (Left Exposure) group, meanwhile, another 31 subjects were named as RE (Right Exposure) group with mobile phone on the right ear. Each group has 3 sessions of EEG recordings, such as Before, During and After Exposure of mobile phone, each session takes 5 minutes and 1 minute rest is applied between sessions. The study proposes index of human brain activities as an indicator of human emotion under mobile RF Radiation using EEG power spectrum, and brainwave signals were employed using nonparametric method. The results of the study established 2 types of indexes according to the trend of Frontal Hemispheric Energy Spectral Density (ESD) between 2 different sessions (from Before session to During session, and from During session to After session) which present human's brain activities.
