Suppose the maximum safe average intensity of microwaves for human exposure is taken to be 1.00 w/m2. if a radar unit leaks 10.0 w of microwaves (other than those sent by its antenna) uniformly in all directions, how far away must you be to be exposed to an average intensity considered to be safe? assume that the power spreads uniformly over the area of a sphere with no complications from absorption or reflection.

at r= 0.56 m far away must you be to be exposed to an average intensity considered to be safe

Explanation:

The maximum safe average intensity of microwaves for human exposure is taken to be 1.00 W/m^2

heat leaked by radar P= 10.0 W

uniformly in the all directions.

Intensity at a distance a r is given by

for safe exposure I= 2.5 W/m^2

and P= 10 W

on calculating we get

r= 0.56 m

at r= 0.56 m far away must you be to be exposed to an average intensity considered to be safe

i would say

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
