Abstract: The radiation from mobile towers affect tissues in the human body. The electrons are stripped away from atoms by splitting some chemical links. In our paper the shielding performance of various materials like aluminum sheet, mumetal, and super-alloy with different thickness is evaluated in terms of reflection loss (RL), re-reflection factor (RRF) and absorption loss (AL). Aluminum acts as a good corrosive in marine, and atmospheric environment. This is very appropriate for the decorative applications, due to its high reflective property. The composition of the particular material contains 16% iron, 5% copper, 2% chromium, and 77% nickel. The soft ferromagnetic alloy of mumetal contains the nickel iron with high permeability, and it is suitable for shielding against low-frequency magnetic fields. It contains 32%-67% iron, 15%-22% chromium, and 9%-38% nickel. The power density values obtained from the shielding effectiveness are converted into specific absorption rate and it is compared with the ICNIRP standard value to show the effectiveness of shielding material. While comparing with the other materials, it is observed that aluminum sheet is the most radiation absorption and protective shielding material against the radiation from cell towers.
