A student walks into a research laboratory and happens to see a label stating that a bottle contains the radioactive isotope, 32P.  The student quickly moves to the far side of the lab.  Initially, the student was about 1 m from the radioactive source and now they are about 6 m away.  The student did a quick calculation and was relieved to know that they had reduced their exposure to 1/x of what it would have been if they had not moved.  Determine the value of x.

THE CORRECT ANSWER IS 25. He started 1 m away, and moved to 6 m away, so you have to do 6-1=5. 1/x = 1/25 >>>>>>>>>>>>>>>>>>>>>>>>> so the answer is: x = 25
