Mokokchung, 14 October (MTNews): The bi-monthly seminar of Fazl Ali College, Mokokchung, was held on 12 October at the FAC Conference Hall with Nukshimoa, Assistant Professor in the Department of Physics, as the resource person. Nukshimoa spoke on the topic, “Electromagnetic Waves and the Science of Communication.”
In his presentation, he discussed the concept of radio waves and how they are used for communication purposes in mobile phones, radios, televisions, satellite navigation radars, and microwave ovens. He elaborated on how communication occurs through electromagnetic waves.
While explaining electromagnetic signal transmission from cell phone antennas, Nukshimoa mentioned that the increased use of cell phones has raised various concerns, including potential health hazards. He explained that electromagnetic radiation from cell phones generates heat and raises the temperature of the head.
”Experiments have shown that radiation penetrates the skull of an adult by 25%, 50% in 10-year-olds, and 75% in 5-year-olds,” he stated. “The younger the child, the deeper the penetration, as their skulls are thinner, and their brain cells contain more fluid than adults.” He also discussed additional points on how specific measures and precautions can be taken.
The seminar concluded with a question and answer session.
