Radiation machines, used to treat tuners, produce in intesty [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 1.7 meters?
==============
They treat tumors, not tuners.
------
Intensity = k/d^2
---
I = 62.5*(3^2/1.7^2)
I =~ 194.64 mroentgen/hr
