Analysis of Radiation Emitted from the Smart Mobiles Screens in the Dark Rooms

The required radiation analysis of the smart mobiles screens which have become associated with us as a fundamental and important communication implement in facilitating with our daily lives. Despite the many types of smart phones sold in the local markets, the study was dedicated to the selection of mobiles common to use by the people of Iraq for the purpose of analysis radiation emitted from these mobiles screens are (A). SAMSUNG Galaxy, (B). SAMSUNG-S7 edge) C). HUWAEI. (D). I Phone The emitted radiation spectra of these mobiles screens analyzed the UV-Visible Spectrophotometer, manufactured by LABOMED, INC. American origin located in the central laboratories at the University of Basra, Iraq. The results obtained after determining the wavelengths emitted from the mobiles screens covering the majority of the UV region and the whole visible area are ( 190, 200, 300, 400, 500 600, 700 nm). The spectra are recorded by the device detector where the absorption of UV and visible regions are ranged between (0.257) as the lowest value and (2.175) as the highest value for the mobiles under study, while the absorption of the source of the device are ranged between (0.008) as the lowest value and (0.121) for the highest value. The UV radiation region is recorded the highest value of (6.53 eV) at the wavelength (190 nm). The results of this work confirm the emission of harmful UV radiation on human health, especially when using smart mobiles in the dark rooms at night and near the eyes of the users.
