Most cellular 'phone systems work around 600Mhz - in the region of 1m wavelengths. Electromagnetic radiation doesn't have the energy required to displace electrons (i.e. what we'd call "ionising radiation") until you get up to ultraviolet light (that's why it causes sunburn) up at around 400nM wavelength - around 21 octaves higher frequency. That's why TV/Radio/mobiles DON'T cause cancer.Now that's not to say EM radiation can't cause trouble at lower frequencies, but if it does it's chiefly from inducing heating effects; microwave ovens that operate in the 1cm wavelengths. Radar technicians and broadcast engineers have a device that monitors their body temperature as you may not notice the slow increase before it becomes dangerous (the frog in slowly boiling water).
In modern technology world cellular telephone towers is a safe installing in school. This is completely approaching by school board. I appreciate with because it is well being of students. Completely we use the sunlight for this project.
