Our Students namely P.Prasanth,V.S.Dinesh and J.S.Nandha kumar   explained the general public  how to use the mobile phone during night  and also  explained about the health issues of handling the mobile  phones for a long time. They educated the people  by  demonstrating on how low levels of RF radiation emitted by mobile phones could cause health problems such as headaches or brain tumours. It was a good experience for the students to motivate the public about the hazards of indiscriminate use of mobile phone.
