Reduce+celluar+radiation

There is big issue regarding the radiation from celluare antenna and celluar cell phones. The celluar service exists since 1985 and in the last 10 years there are a lot of discoveries and surveys dealling with the effects of the celluar radiation on pepole. I think that today we can't imagine our life without cell phones, but we need to know how to use it correctly. I mean that at home it is more safe and economic to use the regular phone. A lot of researchers check if there is a connection between too much exposure to celluar radiation and the Cancer illness. Pepole shouldn't use the cell phone when they don't realy need it.
