Detail Health Hazard Due To Non-Ionizing Radiation From Mobile Phones In Bangladesh   Oleh:  Hoque, A. K. M.Fazlul ; Hossain, M.S ; Zaman, M.A ; Mollah, A.S Jenis: Article from Proceeding Dalam koleksi: Asian Network for Quality (ANQ) Congress 2011, Ho Chi Minh City, Vietnam, 27-30 September 2011 Topik: Non-Ionizing Radiation; Maximum Power Density; Specific Absorption Rate (SAR) Fulltext: BD1 Dr_F_Hoque_Full Paper.pdf (144.0KB) Isi artikel In the work exposure to the non-ionizing electro-magnetic radiation from the antennas of some mobile cellular telephone operators of Bangladesh has been investigated. The frequency range covered in the investigation is 825 MHz to 960 MHz. Calculations were done for mean power at the aperture, maximum power density in the near- and far-fields, distance to the far field, specific absorption rate (SAR) and consequent rise of temperature in human tissues. Maximum power density value (for far field) observed is that for the BanglaLink operator (=1.27x10-6 W/m2). SAR values and the corresponding temperature rise were calculated for the eye, brain and nerve tissues exposed to RF fields, for the general public and occupational workers of Bangladesh for each of the mobile operators. Among the tissues, eye showed the highest and nerves the lowest SAR values. Of all the 4 operators Grameenphone possesses the highest SAR values (approximately 1.6 W/kg), still remaining within the FCC (Federal Communications Commission) and other safety limits (=1.6 W/kg). Temperature rise within 6 minutes time as a consequence of absorption of RF radiation from mobile operators is of the range 0.022 to 0.763 K.
