Abstract
Mobile devices and internet have become the integral part of our everyday life. These devices are being used for many purposes such as for internet and telecommunication. The purpose of this study is to investigate the perception of tertiary institution students towards the hidden health dangers of mobile devices and internet usage. These devices emit harmful radiations which cause diseases like: male infertility, brain tumor, hearing impairment, fetus, and effect on eyes. This study investigated the perception of students towards the reality of some major diseases, such as, brain tumor, male infertility cancer, visual and hearing impairment and so on through wrong usage of mobile devices and internet. The survey was conducted on students from the Computer Science departments of the state-owned tertiary institutions in Lagos, Nigeria. The instrument used was validated at a reliability co-efficient value of 0.77.The result collected revealed that most students are either ignorant or non-challant about the imminent danger of the wrong usage of mobile internet devices to the human health. Recommendations suggested concerted effort to create an awareness to avert the latent danger posed to the Nigerian population through wrong usage of mobile internet devices in order to maintain healthy society
