Recently,some schools in the classroom have installed cell phone jammers in the classroom to prevent  the students from calling, playing with phone so as to improve the quality of teaching .
But many parents worry about whther the long-term using of a cell phone jammer will do harm to the health of the students, because they said that electromagnetic radiation will have student health hazarded.
the experts said, "these small jammers will  not hazard the student body at all..."They pointed out that Jammers will only jam the signal between the phone and base station link,  the base station and other electronic devices won't be jammed , and there is not any effect on the surrounding environment .Moreover, experiences they maded have showed that the phone can be used normally in the stairs and playground.
However,some parents thought that what some experts have said is very irresponsible.in an interview, The inventor of mobile phone signal jammers have pointed out that mobile phone signal jammer works for the long hours,
students are subjected to a longer period of microwave radiation,  the self-immunity of the body can not keep up working, and the health will be endangered in the long time.
As well as I'm concerned ,both of them are reasonable.The topic will be controversial for a long time.
