i'm a high school student in the Phils. we have this investigatory project due in three weeks and unfortunately, our first topic which we have been studying for 5 months now cannot be tested because the equipment is not available here in our country. so our group thought of a new topic and that is to find out a coating which can be applied to cellphones which can lessen the persons exposure to UV coming from cellphones.can anyone suggest and give me background on this matter. i was thinking if it would be possible if you guys give a possible liquid UV curable substance for our study( maybe a substance which is not used for this purpose but has potential to be used as such. or any other liquid substance which has potential. the substance must by the way be UV curable in the first place)

UV is part of the light spectrum (short wave just beyond violet). It is given off by the sun, welding torches and UV lights. Cell phones do not give off UV radiation. While there are UV curable coatings putting one on a cell phone will probably ruin it and accomplish nothing good in the process. You are probably thinking of microwave radiation (long wavelength compared to light). A UV curable coating is transparent to this.

I'm pretty sure you don't get UV radiation from cellphones - just IR (if it heats up a lot) and radio/microwave in the safe parts of the spectrum. That should be the first thing you check out before proceeding.

Have to agree with the others! UV is invisible light and if you try to sheild a person using a cell phone with metal will damage the cell phone eventually.
