Hi Pphius, the School and university projects/Polytechnic of Namibia project page is not the place to write Wikipedia content. Please do that in your user space, see help here. I copied the text you submitted below, but please consider that there already is extensive coverage on cell phones and their perceived health danger on Wikipedia.

''Cell phones have become indispensable devices in our daily life. These phones operate between 400 MHz and 2000 MHz frequency bands and emit radiofrequency electromagnetic waves (EMW). Reports of potential adverse effects of radiofrequency EMWon brain, heart, endocrine system, and DNA of humans and animals are widely reported in the literature. Electromagnetic waves alter brain electroencephalographic activity and cause disturbance in sleep (1); cause difficulty in concentration, fatigue, and headache (2); and increase reaction time in a time-dependent manner (3). They increase the resting blood pressure (4) and reduce the production of melatonin (5). REFERENCES 1. Huber R, Graf T, Cote KA, Wittmann L, Gallmann E, Matter D, et al.
