Not a problem !
At that range the "microwave" effect of your radar is not a problem to do any damage a person would have to be within about 50 feet ( if my memory serves me correctly ).
However I am told that the BA ground engineers at LHR "killed" a police radar speed gun that was being used on the ramp by giving it one or two sweeps of the WX radar from a 757.
I can only think that the gun was looking for an RF return of about 0.075W and got 200W from the 757 !.
