Suppose the maximum safe intensity of microwaves for human exposure is taken to be 1.48~\mathrm{watts/m^2}1.48 watts/m 2 . if a radar unit leaks 10.0~\text{watts}10.0 watts of microwaves (other than those sent by its antenna) uniformly in all directions, how far away must you be to be exposed to an intensity considered to be safe? recall that watts = joules/second = power = energy per unit time. assume that the power of the electromagnetic waves spreads uniformly in all directions (i. e. spreads out over the area of a sphere) and use the formula for the surface area of a sphere.
