Actually Veg, you appeared to indicate not that you were concerned about your child's health, but the health of all children at a Primary School, despite really not knowing the first thing about the subject - apparently.
Look around to see how many Radio Amateurs, of long standing, are also bee keepers. I think that they would have noticed if the bees went bonkers when they were nattering to their mates on the other side of the country/world. Some of them use Morse code because it's a well known fact that bees don't read Morse and so you can talk about them quite freely.
Concerning your child's health and that of other children, I take it that until he or she is of a much less tender age, then ownership of a mobile phone will be well out of the question? No big-M beefburgers either?
Do you get concerned when other young children in your child's class have mobile phones at all, and what if anything do you do about it? This presents a more realistic problem than phone masts which if anything radiate well above the ground and the significant radiation envelope gets to ground level a significant distance from the mast.
Do you have a wifi router operating in your living room at all? Frequency slightly under that of your microwave. You might be paranoid if you thought your microwave was leaking despite it running for only a few minutes at a time, but does your router run 24x7 like mine? Is it a concern to you at all.
I firmly believe that all people that feel mobile phone masts might be risky should have their mobile phone service terminated pronto. How big an outcry would there be then I ask myself.
I have two phone masts 50m from my front door and still we don't get to glow in the dark.
I once read that you can hang a large piece of meat at the hive entrance and the bees will ignore it. If I were you, I wouldn't try exposing meat near the bees in a bid to prove the theory one way or the other
