Radiation machines, used to treat tumors, produce an intensity of radiation that varies
inversely as the square of the distance from the machine. At 3 meters, the radiation intensity is
62.5 milliroentgens per hour. What is the intensity at a distance of 3.3 meters?Radiation machines, used to treat tumors, produce an intensity of radiation that varies inversely as the squar?
so easy.....let it be x
x/62.5 = (3/3.3)^2
x = 51.65 milliroentgens/hr.
